Major Landforms: Cuba is the 17th largest island in the world. Sierra Maestra mountain range, Sierra Cristal Mountains, Escambray Mountains, Pico Turquino Mountain, and Zapata Swamp.
Cuba is composed mostly of limestone, a soft, porous rock that easily erodes. As a result, the island is honeycombed with caves and has the highest density of caves of any place on earth. There are also steep mountain ranges: the Sierra de los Ãrganos, the Sierra de Trinidad, and the Sierra Maestras.
