Greater Antilles

The "Greater Antilles" refers to Cuba, Jamaica, Hispaniola (Haiti and the Dominican Republic), and Puerto Rico. The smaller islands in the vicinity of these four major islands are sometimes also treated as part of the group. This includes the smaller islands that surround the main islands, but are still part of the main island country (for instance, the Republic of Cuba consists of the island of Cuba, the Isle of Pines, and several smaller islands around them.) The Cayman Islands are also often included in the Greater Antilles because of their geographical proximity to Cuba. The Greater Antilles are made up of continental rock, part of North America, as distinct from that of the Lesser Antilles, which are mostly young volcanic or coral islands.
The Yucatan Channel separates the Greater Antilles from Mexico, and the Florida Straits separate them from the United States. To the South of the Greater Antilles, and completely surrounding Jamaica, is the Caribbean Sea.
