Slide 31 of 36: Bordered by Jordan and Israel, the landlocked Dead Sea is the lowest and saltiest body of water on Earth. However, the sea's buoyant waters are now receding, causing sinkholes to appear. The water level of the Dead Sea is said to be dropping by approximately three feet (1m) a year. About 50 years ago, the Dead Sea covered around 386 square miles (1,000sq km), a level that had been largely constant since records began in the early 18th century. It has now shrunk to around 259 square miles (670sq km).
