The Caribbean physical map
Physiographically, the Caribbean region is primarily a chain of islands that surround the Caribbean Sea. To the north, the region borders the Gulf of Mexico, the Strait of Florida and the North Atlantic Ocean, which is to the east and northeast. To the south is the coast of the continent of South America.
Situated largely on the Caribbean Plate, the region comprises more than 700 islands, islets, reefs and cays. These islands generally form island arcs that delineate the eastern and northern edges of the Caribbean Sea. The Caribbean islands, consisting of the Greater Antilles on the north and the Lesser Antilles on the south and east (including the Leeward Antilles), are part of the somewhat larger West Indies grouping, which also includes the Lucayan Archipelago (comprising the Bahamas and Turks and Caicos Islands).
The geography and climate in the Caribbean region varies: Some islands in the region have relatively flat terrain of non-volcanic origin. These islands include Aruba (possessing only minor volcanic features), Curaçao, Barbados, Bonaire, the Cayman Islands, Saint Croix, the Bahamas, and Antigua. Others possess rugged towering mountain-ranges like the islands of Saint Martin, Cuba, Hispaniola, Puerto Rico, Jamaica, Dominica, Montserrat, Saba, Sint Eustatius, Saint Kitts, Saint Lucia, Saint Thomas, Saint John, Tortola, Grenada, Saint Vincent, Guadeloupe, Martinique and Trinidad and Tobago.
