Oeschinen Lake in the Swiss Alps

A lake is a body of relatively still fresh or salt water of considerable size, localized in a basin, that is surrounded by land apart from a river, stream, or other form of moving water that serves to feed or drain the lake. Lakes are inland and not part of the ocean and therefore are distinct from lagoons, and are larger and deeper than ponds.^[1][2] Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.

Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.

Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.

Etymology, meaning, and usage of "lake"[link]

Lake Tahoe on the border of California and Nevada

The Caspian Sea is either the world's largest lake or a full-fledged sea.^[3]

The word lake comes from Middle English lake ("lake, pond, waterway"), from Old English lacu ("pond, pool, stream"), from Proto-Germanic *lakō ("pond, ditch, slow moving stream"), from the Proto-Indo-European root *leg'- ("to leak, drain"). Cognates include Dutch laak ("lake, pond, ditch"), Middle Low German lāke ("water pooled in a riverbed, puddle"), German Lache ("pool, puddle"), and Icelandic lækur ("slow flowing stream"). Also related are the English words leak and leach.

There is considerable uncertainty about defining the difference between lakes and ponds, and no current internationally accepted definition of either term across scientific disciplines or political boundaries exists.^{[citation needed]} For example, limnologists have defined lakes as water bodies which are simply a larger version of a pond, which can have wave action on the shoreline or where wind-induced turbulence plays a major role in mixing the water column. None of these definitions completely excludes ponds and all are difficult to measure. For this reason there has been increasing use made of simple size-based definitions to separate ponds and lakes. One definition of lake is a body of water of 2 hectares (5 acres) or more in area,^[4]:331[5] however others^[who?] have defined lakes as waterbodies of 5 hectares (12 acres) and above,^{[citation needed]} or 8 hectares (20 acres) and above^{[citation needed]} (see also the definition of "pond"). Charles Elton, one of the founders of ecology, regarded lakes as waterbodies of 40 hectares (99 acres) or more.^[6] The term lake is also used to describe a feature such as Lake Eyre, which is a dry basin most of the time but may become filled under seasonal conditions of heavy rainfall. In common usage many lakes bear names ending with the word pond, and a lesser number of names ending with lake are in quasi-technical fact, ponds.

In lake ecology the environment of a lake is referred to as lacustrine. Large lakes are occasionally referred to as "inland seas," and small seas are occasionally referred to as lakes, such as Lake Maracaibo, which is actually a bay.

Distribution of lakes[link]

The Seven Rila Lakes are a group of glacial lakes in the Bulgarian Rila mountains.

Wayanad District Kerala India

The majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes. Canada, with a deranged drainage system has an estimated 63,504 lakes.^[7] Finland has 187,888 lakes of which 60,000 are large.^[8]

Most lakes have at least one natural outflow in the form of a river or stream, which maintain a lake's average level by allowing the drainage of excess water.^[9] Some lakes do not have a natural outflow and lose water solely by evaporation or underground seepage or both. They are termed endorheic lakes.

Many lakes are artificial and are constructed for hydro-electric power generation, aesthetic purposes, recreational purposes, industrial use, agricultural use or domestic water supply.

Evidence of extraterrestrial lakes exists; "definitive evidence of lakes filled with methane" was announced by NASA^{[citation needed]} as returned by the Cassini Probe observing the moon Titan, which orbits the planet Saturn.

Globally, lakes are greatly outnumbered by ponds: of an estimated 304-million standing water bodies worldwide, 91 percent are 1 hectare (2.5 acres) or less in area (see definition of ponds).^[10] Small lakes are also much more numerous than large lakes: in terms of area, one-third of the world's standing water is represented by lakes and ponds of 10 hectares (25 acres) or less.^{[citation needed]} However, large lakes account for much of the area of standing water with 122 large lakes of 1,000 square kilometres (390 sq mi, 100,000 ha, 247,000 acres) or more representing about 29 percent of the total global area of standing inland water.^{[citation needed]}

Origin of natural lakes[link]

A portion of the Great Salt Lake in Utah, United States

Salt crystals, on the shore of Lake Urmia, Iran

There are a number of natural processes that can form lakes. A recent tectonic uplift of a mountain range can create bowl-shaped depressions that accumulate water and form lakes. The advance and retreat of glaciers can scrape depressions in the surface where water accumulates; such lakes are common in Scandinavia, Patagonia, Siberia and Canada. The most notable examples are probably the Great Lakes of North America.

Lakes can also form by means of landslides or by glacial blockages. An example of the latter occurred during the last ice age in the U.S. state of Washington, when a huge lake formed behind a glacial flow; when the ice retreated, the result was an immense flood that created the Dry Falls at Sun Lakes, Washington.

Salt lakes (also called saline lakes) can form where there is no natural outlet or where the water evaporates rapidly and the drainage surface of the water table has a higher-than-normal salt content. Examples of salt lakes include Great Salt Lake, the Aral Sea and the Dead Sea.

Small, crescent-shaped lakes called oxbow lakes can form in river valleys as a result of meandering. The slow-moving river forms a sinuous shape as the outer side of bends are eroded away more rapidly than the inner side. Eventually a horseshoe bend is formed and the river cuts through the narrow neck. This new passage then forms the main passage for the river and the ends of the bend become silted up, thus forming a bow-shaped lake.

Crater lakes are formed in volcanic craters and calderas which fill up with precipitation more rapidly than they empty via evaporation. Sometimes the latter are called caldera lakes, although often no distinction is made. An example is Crater Lake in Oregon, located within the caldera of Mount Mazama. The caldera was created in a massive volcanic eruption that led to the subsidence of Mount Mazama around 4860 BC.

Gloe Lakes are freshwater lakes that have emerged when the water they consists of has been separated, not considerably long before, from the sea as a consequence of post-glacial rebound.

Some lakes, such as Lake Jackson in Florida, USA, come into existence as a result of sinkhole activity.

Lake Vostok is a subglacial lake in Antarctica, possibly the largest in the world. The pressure from the ice atop it and its internal chemical composition mean that, if the lake were drilled into, a fissure could result that would spray somewhat like a geyser.

Most lakes are geologically young and shrinking since the natural results of erosion will tend to wear away the sides and fill the basin. Exceptions are those such as Lake Baikal and Lake Tanganyika that lie along continental rift zones and are created by the crust's subsidence as two plates are pulled apart. These lakes are the oldest and deepest in the world. Lake Baikal, which is 25-30 million years old, is deepening at a faster rate than it is being filled by erosion and may be destined over millions of years to become attached to the global ocean. The Red Sea, for example, is thought to have originated as a rift valley lake.

Types of lakes[link]

Many lakes can have tremendous cultural importance. The West Lake of Hangzhou has inspired romantic poets throughout the ages, and has been an important influence on garden designs in China, Japan and Korea.^[11]

These kettle lakes in Alaska were formed by a retreating glacier.

Ephemeral 'Lake Badwater', a lake only noted after heavy winter and spring rainfall, Badwater Basin, Death Valley National Park.

• Periglacial lake: Part of the lake's margin is formed by an ice sheet, ice cap or glacier, the ice having obstructed the natural drainage of the land.
• Subglacial lake: A lake which is permanently covered by ice. They can occur under glaciers, ice caps or ice sheets. There are many such lakes, but Lake Vostok in Antarctica is by far the largest. They are kept liquid because the overlying ice acts as a thermal insulator retaining energy introduced to its underside by friction, by water percolating through crevasses, by the pressure from the mass of the ice sheet above or by geothermal heating below.
• Glacial lake: a lake with origins in a melted glacier, such as a kettle lake.
• Artificial lake: A lake created by flooding land behind a dam, called an impoundment or reservoir, by deliberate human excavation, or by the flooding of an excavation incident to a mineral-extraction operation such as an open pit mine or quarry. Some of the world's largest lakes are reservoirs like Hirakud Dam in India.
• Endorheic lake, terminal or closed: A lake which has no significant outflow, either through rivers or underground diffusion. Any water within an endorheic basin leaves the system only through evaporation or seepage. These lakes, such as Lake Eyre in central Australia or the Aral Sea in central Asia, are most common in desert locations.
• Meromictic lake: A lake which has layers of water which do not intermix. The deepest layer of water in such a lake does not contain any dissolved oxygen. The layers of sediment at the bottom of a meromictic lake remain relatively undisturbed because there are no living aerobic organisms.
• Fjord lake: A lake in a glacially eroded valley that has been eroded below sea level.
• Oxbow lake: A lake which is formed when a wide meander from a stream or a river is cut off to form a lake. They are called "oxbow" lakes due to the distinctive curved shape that results from this process.
• Rift lake or sag pond: A lake which forms as a result of subsidence along a geological fault in the Earth's tectonic plates. Examples include the Rift Valley lakes of eastern Africa and Lake Baikal in Siberia.
• Underground lake: A lake which is formed under the surface of the Earth's crust. Such a lake may be associated with caves, aquifers or springs.
• Crater lake: A lake which forms in a volcanic caldera or crater after the volcano has been inactive for some time. Water in this type of lake may be fresh or highly acidic, and may contain various dissolved minerals. Some also have geothermal activity, especially if the volcano is merely dormant rather than extinct.
• Lava lake: A pool of molten lava contained in a volcanic crater or other depression. Lava lakes that have partly or completely solidified are also referred to as lava lakes.
• Former: A lake which is no longer in existence. Such lakes include prehistoric lakes and lakes which have permanently dried up through evaporation or human intervention. Owens Lake in California, USA, is an example of a former lake. Former lakes are a common feature of the Basin and Range area of southwestern North America.
• Ephemeral lake, intermittent lake, or seasonal lake: A seasonal lake that exists as a body of water during only part of the year.
• Shrunken: Closely related to former lakes, a shrunken lake is one which has drastically decreased in size over geological time. Lake Agassiz, which once covered much of central North America, is a good example of a shrunken lake. Two notable remnants of this lake are Lake Winnipeg and Lake Winnipegosis.
• Eolic lake: A lake which forms in a depression created by the activity of the winds.
• Vlei, in South Africa, shallow lakes which vary considerably with seasons.
• Epitshelf Lakes, unique lakes which exist on top of a dense saltwater body and are surrounded by ice. These are mostly found in the Arctic.

Characteristics[link]

Lake Päijänne is one of tens of thousands of lakes in Finnish Lakeland.

Lake Mapourika, New Zealand

Lakes have numerous features in addition to lake type, such as drainage basin (also known as catchment area), inflow and outflow, nutrient content, dissolved oxygen, pollutants, pH, and sedimentation.

Changes in the level of a lake are controlled by the difference between the input and output compared to the total volume of the lake. Significant input sources are precipitation onto the lake, runoff carried by streams and channels from the lake's catchment area, groundwater channels and aquifers, and artificial sources from outside the catchment area. Output sources are evaporation from the lake, surface and groundwater flows, and any extraction of lake water by humans. As climate conditions and human water requirements vary, these will create fluctuations in the lake level.

Lakes can be also categorized on the basis of their richness in nutrients, which typically affect plant growth. Nutrient-poor lakes are said to be oligotrophic and are generally clear, having a low concentration of plant life. Mesotrophic lakes have good clarity and an average level of nutrients. Eutrophic lakes are enriched with nutrients, resulting in good plant growth and possible algal blooms. Hypertrophic lakes are bodies of water that have been excessively enriched with nutrients. These lakes typically have poor clarity and are subject to devastating algal blooms. Lakes typically reach this condition due to human activities, such as heavy use of fertilizers in the lake catchment area. Such lakes are of little use to humans and have a poor ecosystem due to decreased dissolved oxygen.

Due to the unusual relationship between water's temperature and its density, lakes form layers called thermoclines, layers of drastically varying temperature relative to depth. Fresh water is most dense at about 4 degrees Celsius (39.2 °F) at sea level. When the temperature of the water at the surface of a lake reaches the same temperature as deeper water, as it does during the cooler months in temperate climates, the water in the lake can mix, bringing oxygen-starved water up from the depths and bringing oxygen down to decomposing sediments. Deep temperate lakes can maintain a reservoir of cold water year-round, which allows some cities to tap that reservoir for deep lake water cooling.

Lake Teletskoye, Siberia

Since the surface water of deep tropical lakes never reaches the temperature of maximum density, there is no process that makes the water mix. The deeper layer becomes oxygen starved and can become saturated with carbon dioxide, or other gases such as sulfur dioxide if there is even a trace of volcanic activity. Exceptional events, such as earthquakes or landslides, can cause mixing which rapidly brings the deep layers up to the surface and release a vast cloud of gas which lay trapped in solution in the colder water at the bottom of the lake. This is called a limnic eruption. An example is the disaster at Lake Nyos in Cameroon. The amount of gas that can be dissolved in water is directly related to pressure. As deep water surfaces, the pressure drops and a vast amount of gas comes out of solution. Under these circumstances carbon dioxide is hazardous because it is heavier than air and displaces it, so it may flow down a river valley to human settlements and cause mass asphyxiation.

The material at the bottom of a lake, or lake bed, may be composed of a wide variety of inorganics, such as silt or sand, and organic material, such as decaying plant or animal matter. The composition of the lake bed has a significant impact on the flora and fauna found within the lake's environs by contributing to the amounts and the types of nutrients available.

A paired (black and white) layer of the varved lake sediments correspond to a year. During winter, when organisms die, carbon is deposited down, resulting to a black layer. At the same year, during summer, only few organic materials are deposited, resulting to a white layer at the lake bed. These are commonly used to track past paleontological events.

Limnology[link]

Lake Billy Chinook, Deschutes National Forest, Oregon.

Lake Cugun, Kirsehir, Turkey.

Limnology is the study of inland bodies of water and related ecosystems. Limnology divides lakes into three zones: the littoral zone, a sloped area close to land; the photic or open-water zone, where sunlight is abundant; and the deep-water profundal or benthic zone, where little sunlight can reach. The depth to which light can reach in lakes depends on turbidity, determined by the density and size of suspended particles. A particle is in suspension if its weight is less than the random turbidity forces acting upon it. These particles can be sedimentary or biological in origin and are responsible for the color of the water. Decaying plant matter, for instance, may be responsible for a yellow or brown color, while algae may cause greenish water. In very shallow water bodies, iron oxides make water reddish brown. Biological particles include algae and detritus. Bottom-dwelling detritivorous fish can be responsible for turbid waters, because they stir the mud in search of food. Piscivorous fish contribute to turbidity by eating plant-eating (planktonivorous) fish, thus increasing the amount of algae (see aquatic trophic cascade). The light depth or transparency is measured by using a Secchi disk, a 20-cm (8 in) disk with alternating white and black quadrants. The depth at which the disk is no longer visible is the Secchi depth, a measure of transparency. The Secchi disk is commonly used to test for eutrophication. For a detailed look at these processes, see lentic ecosystems.

A lake moderates the surrounding region's temperature and climate because water has a very high specific heat capacity (4,186 J·kg⁻¹·K⁻¹). In the daytime a lake can cool the land beside it with local winds, resulting in a sea breeze; in the night it can warm it with a land breeze.

How lakes disappear[link]

The lake may be infilled with deposited sediment and gradually become a wetland such as a swamp or marsh. Large water plants, typically totos, accelerate this closing process significantly because they partially decompose to form peat soils that fill the shallows. Conversely, peat soils in a marsh can naturally burn and reverse this process to recreate a shallow lake. Turbid lakes and lakes with many plant-eating fish tend to disappear more slowly. A "disappearing" lake (barely noticeable on a human timescale) typically has extensive plant mats at the water's edge. These become a new habitat for other plants, like peat moss when conditions are right, and animals, many of which are very rare. Gradually the lake closes and young peat may form, forming a fen. In lowland river valleys where a river can meander, the presence of peat is explained by the infilling of historical oxbow lakes. In the very last stages of succession, trees can grow in, eventually turning the wetland into a forest.

Some lakes can disappear seasonally. These are called intermittent lakes, ephemeral lakes, or seasonal lakes and can be found in karstic terrain. A prime example of an intermittent lake is Lake Cerknica in Slovenia or Lag Prau Pulte in Graubünden. Other intermittent lakes are only the result of above-average precipitation in a closed, or endorheic basin, usually filling dry lake beds. This can occur in some of the driest places on earth, like Death Valley. This occurred in the spring of 2005, after unusually heavy rains.^[12] The lake did not last into the summer, and was quickly evaporated (see photos to right). A more commonly filled lake of this type is Sevier Lake of west-central Utah.

Sometimes a lake will disappear quickly. On 3 June 2005, in Nizhny Novgorod Oblast, Russia, a lake called Lake Beloye vanished in a matter of minutes. News sources reported that government officials theorized that this strange phenomenon may have been caused by a shift in the soil underneath the lake that allowed its water to drain through channels leading to the Oka River.^[13]

The presence of ground permafrost is important to the persistence of some lakes. According to research published in the journal Science ("Disappearing Arctic Lakes", June 2005), thawing permafrost may explain the shrinking or disappearance of hundreds of large Arctic lakes across western Siberia. The idea here is that rising air and soil temperatures thaw permafrost, allowing the lakes to drain away into the ground.

Some lakes disappear because of human development factors. The shrinking Aral Sea is described as being "murdered" by the diversion for irrigation of the rivers feeding it.

Extraterrestrial lakes[link]

At present the surface of the planet Mars is too cold and has too little atmospheric pressure to permit the pooling of liquid water on the surface. Geologic evidence appears to confirm, however, that ancient lakes once formed on the surface. It is also possible that volcanic activity on Mars will occasionally melt subsurface ice, creating large lakes.^{[citation needed]} Under current conditions this water would quickly freeze and sublimate unless insulated in some manner, such as by a coating of volcanic ash.

Only one world other than Earth is known to harbor lakes, Saturn's largest moon, Titan. Photographs and spectroscopic analysis by the Cassini–Huygens spacecraft show liquid ethane on the surface, which is thought to be mixed with liquid methane.

Jupiter's small moon Io is volcanically active due to tidal stresses, and as a result sulfur deposits have accumulated on the surface. Some photographs taken during the Galileo mission appear to show lakes of liquid sulfur on the surface.^[14]

There are dark basaltic plains on the Moon, similar to lunar maria but smaller, that are called lacus (singular lacus, Latin for "lake") because they were thought by early astronomers to be lakes of water.

Notable lakes[link]

Round Tangle Lake, one of the Tangle Lakes, located 2,864 feet (873 m) above sea level in interior Alaska

• Lake Michigan-Huron is the largest lake by surface area: 117,350 km². It also has the longest lake coastline in the world: 8,790 km. If Huron and Michigan are considered two lakes, Lake Superior is the largest lake, with 82,414 km². However, Huron still has the longest coastline at 6,157 km (2980 km excluding the coastlines of its many inner islands). The world's smallest geological ocean, the Caspian Sea, at 394,299 km² has a surface area greater than the six largest freshwater lakes combined, and it's frequently cited as the world's largest lake.
• The deepest lake is Lake Baikal in Siberia, with a bottom at 1,637 m. Its mean depth is also the greatest in the world (749 m).
  It is also the world's largest lake by volume (23,600 km³, though smaller than the Caspian Sea at 78,200 km³), and the second longest (about 630 km from tip to tip).
• The longest lake is Lake Tanganyika, with a length of about 660 km (measured along the lake's center line).
  It is also the second largest by volume and second deepest (1,470 m) in the world, after lake Baikal.
• The world's oldest lake is Lake Baikal, followed by Lake Tanganyika (Tanzania).
• The world's highest lake, if size is not a criterion, may be the crater lake of Ojos del Salado, at 6,390 metres (20,965 ft).^[15]
• The highest large (greater than 250 square kilometers) freshwater lake in the world is the 290 km² Pumoyong Tso (Pumuoyong Tso), in the Tibet Autonomous Region of China, at 28-34N 90-24E, 5,018 metres (16,463 ft) above sea level.^[16]

• The northernmost named lake on Earth is Upper Dumbell Lake in the Qikiqtaaluk Region of Nunavut, Canada at a latitude of 82°28'N. It is located only 5.2 kilometers southwest of Alert, the northernmost settlement in the world. There are also several small lakes located north of Upper Dumbell Lake, but they are all unnamed and only appear on very detailed maps.

Largest by continent[link]

The largest lakes (surface area) by continent are:

• Australia – Lake Eyre (salt lake)
• Africa – Lake Victoria, also the third-largest freshwater lake on Earth. It is one of the Great Lakes of Africa.
• Antarctica – Lake Vostok (subglacial)
• Asia – Lake Baikal (if the Caspian Sea is considered a lake, it is the largest in Eurasia, but is divided between the two geographic continents)
• Oceania – Lake Eyre when filled; the largest permanent (and freshwater) lake in Oceania is Lake Taupo.
• Europe – Lake Ladoga, followed by Lake Onega, both located in northwestern Russia.
• North America – Lake Michigan-Huron, which is hydrologically a single lake. However, lakes Huron and Michigan are often considered separate lakes, in which case Lake Superior would be the largest.
• South America – Lake Titicaca, which is also the highest navigable body of water on Earth at 3,821 m above sea level. The much larger Lake Maracaibo is considered by some to be the second-oldest lake on Earth, but since it lies at sea level and nowadays is a contiguous body of water with the sea, others consider that it has turned into a bay.

Richard Mark Hammond (born 19 December 1969) is an English broadcaster, writer, and journalist most noted for co-hosting the car programme Top Gear with Jeremy Clarkson and James May, as well as presenting series 1–4 of Brainiac: Science Abuse on Sky 1. Since 2009, Hammond has co-hosted Total Wipeout with Amanda Byram on BBC One which has since been cancelled.

Hammond is currently presenting Planet Earth Live alongside Julia Bradbury.

Early life[link]

Hammond was born in Solihull and is the grandson of workers in the Birmingham automobile industry.^[3][4] In the mid-1980s Hammond moved with his family (mother Eileen, father Alan, and younger brothers Andrew, writer of the 'Crypt' Series, and Nicholas) to the North Yorkshire cathedral city of Ripon where his father ran a probate business in the market square. Originally a pupil of Solihull School, a fee-paying boys' independent school, he moved to Ripon Grammar School, and from 1987 to 1989 attended Harrogate College of Art and Technology. After his graduation he worked for several radio stations, including Radio Cleveland, Radio York, Radio Cumbria, Radio Leeds, Radio Newcastle and Radio Lancashire, before auditioning for Top Gear.^[5]

Top Gear[link]

Hammond became a presenter on Top Gear in 2002, when the show began in its present format. He is sometimes referred to as "Hamster" by fans and his co-presenters on Top Gear due to his name and comparatively small stature.^[6] His nickname was further reinforced when on three separate occasions in series 7, Hammond ate cardboard,^[7] mimicking hamster-like behaviour. A running gag is Hammond's supposed use of teeth whitener.^[8] In a series 7 episode, co-presenter Jeremy Clarkson claimed to have found a pack of teeth whiteners in a Marcos TSO GT2 that Hammond had tested. Hammond objected, claiming it was a set-up. In a series 10 episode that featured the Peel P50, Clarkson was seen supposedly talking to Hammond on the phone about him considering a tooth whitening treatment costing £4000. Later, during a series 13 episode that featured the presenters in their office searching for car insurance prices, a teeth whitening kit was pictured on his desk. It was staged to appear that he was caught looking at a website on teeth whiteners on Richard Hammond's 5 O'Clock Show.

In the first episode of series 9 broadcast on 28 January 2007, having recovered from his high speed crash Hammond returned to a hero's welcome, complete with dancing girls, aeroplane style stairs and fireworks. The show also contained images of the crash, which had made international headlines, with Hammond talking through the events of the day after which the audience broke into spontaneous applause. Hammond then requested that the crash never be mentioned on the show again, though all three Top Gear presenters have since referred to it in jokes during the news segment of the programme. He told his colleagues, "The only difference between me now, and before the crash, is that I like celery now and I didn't before".^[9]

During the third episode of series sixteen, Hammond suggested that no one would ever want to own a Mexican car, since cars are supposed to reflect national characteristics and so a Mexican car would be a "lazy, feckless, flatulent, overweight oaf." Hammond finished with the remark "I'm sorry, but can you imagine waking up and remembering you're Mexican?!"^[10] Following complaints, the BBC defended the broadcast of this segment on the grounds that such national stereotyping was a "robust part" of traditional British humour.^[11]

Brainiac: Science Abuse[link]

In 2003, Hammond became the first presenter of Brainiac: Science Abuse; he was joined by Jon Tickle with Charlotte Hudson joining in series 2.^[12] After the fourth series it was announced that Hammond was no longer going to present the Sky1 show after he signed an exclusive deal with the BBC. Vic Reeves took his place as main presenter.^[13]

Other television work[link]

Early in his career, as well as his radio work, Hammond presented a number of daytime lifestyle shows and motoring programmes such as Motor Week on Men & Motors.

He presented the Crufts dog show in 2005, the 2004 and 2005 British Parking Awards, and has appeared on School's Out, a quiz show on BBC One where celebrities answer questions about things they learned at school. He has also presented The Gunpowder Plot: Exploding The Legend.^[14] Along with his work on Top Gear, he presented Should I Worry About...? on BBC One, Time Commanders on BBC Two and the first four series of Brainiac: Science Abuse on Sky One. He was also a team captain on the BBC Two quiz show, Petrolheads, in which a memorable part was one where Hammond was tricked into smashing his classic Ferrari while trying to parallel park blindfolded in another car.

From 3 January 2006 until 10 February 2006, Hammond was the eponymous star of Richard Hammond's 5 O'Clock Show with his co-star Mel Giedroyc of Light Lunch fame.^[15] The programme, which discussed a wide range of topics, was shown every weekday on ITV between 17:00 and 18:00.^[15]

While in New Zealand for Top Gear Live 2009, Hammond filmed several television commercials for Telecom New Zealand's new XT UTMS mobile network. Telecom claimed that the new network was "faster in more places", compared to its competitors and its existing CDMA network. After the network repeatedly failed in late 2009 and early 2010, Hammond became the butt of a joke when he did not return to New Zealand for Top Gear Live 2010. His fellow Top Gear co-hosts said he was too embarrassed to come back to New Zealand, and in a supposed live feed back to Hammond, the feed suddenly drops out as the "XT Network had crashed".^[22] Hammond was later given the right of reply to his colleagues during an interview with Marcus Lush on RadioLIVE's breakfast show in New Zealand.^[23]

Hammond is currently hosting the UK version of the US series Wipeout, called Total Wipeout. It takes place in Argentina, and is co-presented by Hammond and Amanda Byram.

Personal life[link]

Hammond has been married to Amanda Etheridge (mostly known as Mindy)^[31] since May 2002; the couple have two daughters.^[3] The family lives in a mock castle in Herefordshire and also has an apartment in London. Hammond also plays the bass guitar, on which he accompanied the other Top Gear presenters when they performed alongside Justin Hawkins on Top Gear of the Pops for Comic Relief in 2007. Hammond likes to ride his bicycle in cities, for which he is mocked mercilessly by fellow presenter Jeremy Clarkson.^[32]

Hammond is a fan of Porsche 911s and claims the Pagani Zonda to be the ultimate supercar. He once owned a 1982 Porsche 911 SC (sold in the mid-2000s),^[33][34] and later purchased a 2006 Porsche 911 (997) Carrera S.^[35] In 2004, Hammond purchased a Porsche 928 for the purpose of daily driving.^[36] Much unlike Clarkson and May, he also has an interest in American muscle cars. Hammond has owned a 1969 Dodge Charger R/T,^[36] a 1967 Ford Mustang GT 390,^[37] and a 2008 Dodge Challenger SRT-8 (which was purchased in the United States on a Series 12 episode of Top Gear).^[38]

Hammond had also owned a Morgan AeroMax, in which he was involved in a car accident on 9 August 2009. He also owns a Jaguar E-Type^[39] and is also a fan of monster trucks, having attended Truckfest '07.

An interview with The Sunday Times in February 2008 reported Hammond as having moved briefly from Gloucestershire to Buckinghamshire, then back again because he missed the country life.^[40]

Hammond is a keen motorcyclist^[41] and Land Rover Defender fan. He spent over £70,000 rebuilding his 110 "Buster" in 2008.^{[citation needed]}

During the news segment of Top Gear's 2010 USA Road Trip special, Hammond openly expressed his dislike of the band Genesis. This fact was later exploited by his co-presenters in two special episodes: during the Middle East Special, when they installed a secret second stereo unit in his Fiat Barchetta that only plays the band's Live over Europe 2007 concert; in the India Special, Clarkson played the same song used in the previous special through the megaphone mounted in his Jaguar XJS, despite Hammond driving a different car (a Mini Cooper Sport).

In October it was reported he had spent over £2 million buying Bollitree Castle which is situated near Weston under Penyard, Ross-on-Wye. It has been rumoured he has also bought a large house in the small town of Wantage, Oxfordshire^{[citation needed]}.^[42][43]

On Top Gear in 2007, Hammond went to Africa on an 'Epic Road Trip' across Botswana. While there he found a 1963 Opel Kadett, in which he drove across Botswana. Hammond named it Oliver. On Top Gear a week after the special was aired, Hammond announced during the news, that he had shipped Oliver back to the UK, where it was restored by a team from Practical Classics magazine. Oliver features on Hammond's children's science television show Richard Hammond's Blast Lab and in another episode of Top Gear as a kind of "Hill-holder" in the trailer truck challenge (after it acquired the personal plate "OLI V3R"). Oliver is also mentioned in Hammond's second autobiography As You Do.^{[citation needed]}

In 2010, Hammond was the President of the 31st Herefordshire Country Fair held at Hampton Court in Hope under Dinmore. His involvement caused unprecedented attendance with "nearly 15,000 people" drawn to the event to meet the presenter.^[45]

In 2010, Hammond gained a private pilot licence PPL(H) in an R44 helicopter.

During season 18 of Top Gear it was revealed that he owns a Fiat 500 TwinAir.

[edit] Vampire dragster crash

During filming of a Top Gear segment at the former RAF Elvington airbase near York on 20 September 2006, Hammond was injured in the crash of the jet-powered car he was piloting.^{[47][48][49]:1} Hammond was travelling at 288 mph (463 km/h) at the time of the crash.^[50]

His vehicle, a dragster called Vampire, was theoretically capable of travelling at speeds of up to 370 mph (595 km/h).^[48] The vehicle was the same car that in 2000, piloted by Colin Fallows, set the British land speed record at 300.3 mph (483.3 km/h).^[49]:3[51] The Vampire was powered by a single Bristol-Siddeley Orpheus afterburning turbojet engine producing 10000 hp (7.5 MW).^[48][50]

Some accounts suggested that the accident occurred during an attempt to break the British land speed record,^[47][52] but the Health and Safety Executive report on the crash found that a proposal to try to officially break the record was vetoed in advance by Top Gear executive producer Andy Wilman, due to the risks and complexities of such a venture.^[49]:4 (The report stated: "Runs were to be carried out in only one direction along a pre-set course on the Elvington runway. Vampire’s speed was to be recorded using GPS satellite telemetry. The intention was to record the maximum speed, not to measure an average speed over a measured course, and for [Hammond] to describe how it felt.")^[49]:1

Hammond was completing a seventh and final run to collect extra footage for the programme when his front-right tyre failed,^[49]:8[53] and, according to witness and first responder Dave Ogden, "one of the parachutes had deployed but it went on to the grass and spun over and over before coming to a rest about 100 yards from us."^[54] The emergency crew quickly arrived at the car, finding it inverted and partially embedded in the grass.^[52] During the roll, Hammond's helmet had embedded itself into the ground, flipping the visor up and forcing dirt into his mouth and left eye, damaging the eye. Rescuers felt a pulse and heard the unconscious Hammond breathing before the car was turned upright.^[52] Hammond was cut free with hydraulic shears, and placed on a backboard.^[49]:9 "He was regaining consciousness at that point and said he had some lower back pain".^[52] He was then transported by the Yorkshire Air Ambulance to the neurological unit of the Leeds General Infirmary.^{[47][49]:9[55]} Hammond's family visited him at the hospital along with Top Gear co-presenters James May and Jeremy Clarkson.^[54][55] Clarkson wished Hammond well, saying "Both James and I are looking forward to getting our 'Hamster' back", referring to Hammond by his nickname.^[47][54]
