North America

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe.

In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands (most notably the Caribbean) are included.

North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago (the beginning of the Archaic or Meso-Indian period). The Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants. European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French and societies and states commonly reflect Western traditions.

Caspian Sea

The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. It is in an endorheic basin (it has no outflows) located between Europe and Asia. It is bounded to the northeast by Kazakhstan, to the northwest by Russia, to the west by Azerbaijan, to the south by Iran, and to the southeast by Turkmenistan. The Caspian Sea lies to the east of the Caucasus Mountains and to the west of the vast steppe of Central Asia. Its northern part, the Caspian Depression, is one of the lowest points on Earth. The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness and large size.

The sea has a surface area of 371,000 km² (143,200 sq mi) (not including its detached lagoon of Garabogazköl Aylagy) and a volume of 78,200 km³ (18,800 cu mi). It has a salinity of approximately 1.2% (12 g/l), about a third of the salinity of most seawater.

Etymology

The word Caspian is derived from the name of the Caspi, an ancient people who lived to the south-west of the sea in Transcaucasia.Strabo wrote that "to the country of the Albanians belongs also the territory called Caspiane, which was named after the Caspian tribe, as was also the sea; but the tribe has now disappeared". Moreover, the Caspian Gates, which is the name of a region in Iran's Tehran province, possibly indicates that they migrated to the south of the sea. The Iranian city of Qazvin shares the root of its name with that of the sea. In fact, the traditional Arabic name for the sea itself is Bahr al-Qazwin (Sea of Qazvin).

America (advertisement)

"America" is an American political advertisement released by the 2016 presidential campaign of Bernie Sanders. It premiered on January 21, 2016 via YouTube, and to air on television in Iowa and New Hampshire shortly before the Democratic Iowa caucus and New Hampshire primary.

Content

The advertisement features "America," a song recorded by Simon & Garfunkel for their album Bookends (1968).

The ad starts with scenes of everyday American life over soft humming and gentle guitar strumming. As the line, "let us be lovers, we'll marry our fortunes together" plays in the background, a middle-aged couple dances at a small Bernie Sanders for President rally. Then Sanders is seen speaking to a few people in a backyard. As the ad continues, the crowds grow larger and more enthusiastic. A montage of many Sanders supporters appear, as the words "They've all come to look for America" flash on the screen. Sanders is then seen addressing a large outdoor gathering, interacting one-on-one with supporters, appearing before more energetic crowds, finally ending in a large auditorium filled to capacity with cheering people.

North

North is a noun, adjective, or adverb indicating direction or geography. North is one of the four cardinal directions or compass points. It is the opposite of south and is perpendicular to east and west.

Etymology

The word north is related to the Old High German nord, both descending from the Proto-Indo-European unit ner-, meaning "down" (or "under"). (Presumably a natural primitive description of its concept is "to the left of the rising sun".)

The Latin word borealis comes from the Greek boreas "north wind, north", which, according to Ovid, was personified as the son of the river-god Strymon, the father of Calais and Zetes. Septentrionalis is from septentriones, "the seven plow oxen", a name of Ursa Maior. The Greek arktikos is named for the same constellation, and is the derivation of the English word "Arctic".

Other languages have sometimes more interesting derivations. For example, in Lezgian, kefer can mean both 'disbelief' and 'north', since to the north of the Muslim Lezgian homeland there are areas formerly inhabited by non-Muslim Caucasian and Turkic peoples. In many languages of Mesoamerica, "north" also means "up". In Hungarian the word for north is észak, which is derived from éjszaka ("night"), since above the Tropic of Cancer, the Sun never shines from the north.

The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.
