Describe the various mountains found throughout Middle America, The Caribbean, and South America

Middle America, the geographic realm between the United States and the continent of South America, consists of three main regions: the Caribbean, Mexico, and the Central American republics. The Caribbean region, the most culturally diverse of the three, consists of more than seven thousand islands that stretch from the Bahamas to Barbados. The four largest islands of the Caribbean make up the Greater Antilles, which include Cuba, Jamaica, Hispaniola, and Puerto Rico. Hispaniola is split between Haiti in the west and the Dominican Republic in the east. The smaller islands, extending all the way to South America, make up the Lesser Antilles. The island that is farthest south is Trinidad, just off the coast of Venezuela. The Bahamas, the closest islands to the US mainland, are located in the Atlantic Ocean but are associated with the Caribbean region. The Caribbean region is surrounded by bodies of salt water: the Caribbean Sea in the center, the Gulf of Mexico to the west, and the North Atlantic to the east.
