It is bounded by the Yucatán Peninsula of Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the north coast of South America.The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts, are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about 2,754,000 km² (1,063,000 sq. mi.). The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,220 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién, Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras.

History

The name "Caribbean" is derived from the Caribs, one of the dominant Native American groups in the region at the time of European contact during the late 15th century. After the discovery of the West Indies by Christopher Columbus in 1492, the Spanish term Antillas was assigned to the lands; stemming from this, "Sea of the Antilles" is a common alternative name for the Caribbean Sea in various European languages. During the first century of development, the Spanish dominance was The Caribbean Sea was an unknown body of water to the populations of Eurasia until 1492, when Christopher Columbus first sailed into Caribbean waters on a quest to find a sea route to Asia. At that time the Western Hemisphere in general was unknown to Europeans. Following the discovery of the islands by Columbus, the area was quickly colonised by several Western cultures (initially Spain, then later Portugal, England, the Dutch Republic, France and Denmark). Following the colonisation of the Caribbean islands, the Caribbean Sea became a busy area for European-based undisputed.

Geology


The Caribbean Sea is an oceanic sea largely situated on the Caribbean Plate. The Caribbean Sea is separated from the ocean by several island arcs of various ages. The youngest of them stretches from the Lesser Antilles to the Virgin Islands to the north east of Trinidad and Tobago off the coast of Venezuela. This arc was formed by the collision of the South American Plate with the Caribbean Plate and includes active and extinct volcanoes such as Mount Pelee, the Quill (volcano) on Sint Eustatius in the Caribbean Netherlands and Morne Trois Pitons on Dominica. The larger islands in the northern part of the sea Cuba, Haiti, Jamaica and Puerto Rico lie on an older island arc. The geological age of the Caribbean Sea is not known with certainty but is estimated to have an age between 160 and 180 million years and was formed by a horizontal fracture that split the supercontinent called Pangea in the Mesozoic Era. It is assumed that the proto-caribbean basin existed in the Devonian period. In the early Carboniferous movement of Gondwana to the north and its convergence with the Euramerica basin decreased in size.
