Mountain range

A mountain range (also mountain barrier/belt/system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.

Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.

Wondrous Ranges

Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera along the Pacific Coast, the Aleutian Range, on through Kamchatka, Japan, Taiwan, the Philippines, Papua New Guinea, to New Zealand. The Andes is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system.

Mountain

A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges.

High elevations on mountains produce colder climates than at sea level. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing.

The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft).

Bob Ross

Robert Norman "Bob" Ross (October 29, 1942 – July 4, 1995) was an American painter, art instructor, and television host. He was best known as the creator and host of The Joy of Painting, an instructional television program that aired from 1983 to 1994 on PBS in the United States, and also aired in Canada, Latin America and Europe.

Biography

Early life

Ross was born in Daytona Beach, Florida, and raised in Orlando, Florida. He had a half-brother, Jim, whom he mentioned in passing on his show. While working as a carpenter with his father, Ross lost part of his left index finger, but it did not affect the way he held his palette while painting.

Personal life

Ross had two sons, Bob and Steven, with his first wife, Lynda Brown. Steven occasionally appeared on The Joy of Painting and became a Ross-certified instructor. The last episode of Season 1 was a question-and-answer forum in which Steven read a series of general "how-to" questions sent in by viewers during the season, and Bob answered them one at a time, technique by technique, until he had completed an entire painting.

Tibetan Plateau

The Tibetan Plateau (Tibetan: བོད་ས་མཐོ།, Wylie: bod sa mtho ), also known in China as the Qinghai–Tibet Plateau or the Qingzang Plateau (Chinese: 青藏高原; pinyin: Qīngzàng Gāoyuán) or Himalayan Plateau, is a vast elevated plateau in Central Asia and East Asia, covering most of the Tibet Autonomous Region and Qinghai Province in western China, as well as part of Ladakh in Jammu and Kashmir state of India. It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. With an average elevation exceeding 4,500 metres (14,800 ft), the Tibetan Plateau is sometimes called "the Roof of the World" and is the world's highest and largest plateau, with an area of 2,500,000 square kilometres (970,000 sq mi) (about five times the size of Metropolitan France). Sometimes termed the "Third Pole", the Tibetan Plateau is the headwaters of the drainage basins of most of the streams in surrounding regions. Its tens of thousands of glaciers and other geographical and ecological features serve as a "water tower" storing water and maintaining flow. The impact of global warming on the Tibetan Plateau is of intense scientific interest.
