Sri Lanka is an island nation located in the Indian Ocean, just off the southeastern coast of India. Despite its modest size—slightly larger than the state of West Virginia—Sri Lanka has a population of about 20 million people, almost equal to the population of Texas. Shaped like a teardrop, the island of Sri Lanka measures about 255 miles (415 km.) from north to south, and about 135 miles (220 km.) from east to west, with a total land area of about 25,300 square miles (65,600 square km.). It has more than 830 miles (1340 km.) of coastline. The island is ringed by a broad coastal plain, rising to an inland terrain of gently rolling hills. A range of mountains dominates the south-central interior, with the highest peak, Mt. Piduruthalagala, reaching more than 8200 feet (2524 meters) in height.
