Originally known to its inhabitants as Raqmu, is a historical and archaeological city in southern Jordan. Petra lies on the slope of Jabal Al-Madbah in a basin among the mountains which form the eastern flank of Arabah valley that run from the Dead Sea to the Gulf of Aqaba. Petra is believed to have been settled as early as 9,000 BC, and it was possibly established in the 4th century BC as the capital city of the Nabataean Kingdom. The Nabataeans were nomadic Arabs who invested in Petra's proximity to the trade routes by establishing it as a major regional trading hub.
The Dead Sea is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. Its surface and shores are 430.5 metres (1,412 ft) below sea level,Earth's lowest elevation on land. The Dead Sea is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2%, (in 2011), it is 9.6 times as salty as the ocean and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea's main, northern basin is 50 kilometres (31 mi) long and 15 kilometres (9 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.
