Top 5 Depressions Of The Earth

1. Dead Sea - Jordan-Israel

The Dead Sea also called the Salt Sea, is a salt lake bordering Israel to the west, and Jordan to the east. Its surface and shores are 422 metres (1,385 ft) below sea level, the lowest elevation on the Earth's surface on dry land. The Dead Sea is 378 m (1,240 ft) deep, the deepest hypersaline lake in the world. It is also one of the world's saltiest bodies of water, with 33.7% salinity, though Lake Assal (Djibouti), Garabogazköl and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond) have reported higher salinities. It is 8.6 times more salty than the ocean. This salinity makes for a harsh environment where animals cannot flourish, hence its name. The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.

2. Lake Assal - Djibouti

Lake Assal is a crater lake in central Djibouti, located at the southern border of Tadjoura Region, touching Dikhil Region, some 120 km (75 mi) west of Djibouti city. It lies 155 m (509 ft) below sea level in the Afar Depression and its shores comprise the lowest point on land in Africa and the second lowest land depression on Earth after the Dead Sea. It measures 19 by 7 km (4.3 mi) and has an area of 54 km2 (21 sq mi). The maximum depth is 40 m (130 ft), whereas the mean depth is 7.4 m (24 ft), which makes for a water volume of 400 million cubic metres (320,000 acre·ft). The catchment area measures 900 km2 (350 sq mi), and there is just a residual runoff of fresh water into the lake.

3. Turpan Depression - China

The Turpan Depression or Turfan Depression is a fault-bounded trough located around and south of the city-oasis of Turpan, in the Xinjiang Autonomous Region in far western China, about 150 km southeast of the provincial capital Ürümqi. It includes the third lowest exposed point on the Earth's surface (dry Lake Ayding, -154m), after the Dead Sea and Lake Assal (Djibouti). It is entirely below sea level. By some measures, it is also the hottest and driest area in China.

4. Qattara Depression - Egypt

The Qattara Depression is a desert basin within the Libyan Desert of northwestern Egypt in the Matruh Governorate. The Depression, at 133 m below sea level, contains the second lowest point in Africa (The lowest being Lake Assal in Djibouti). The Depression covers about 19,500 km² (7,000 square miles), a size comparable to Lake Erie, and at its maximum is 220 km in length and 120 km in width. The bottom of the depression consists of a salt pan.

5. Karagiye - Kazahstan

Karagiye is the lowest point in Kazakhstan. Also called the "Karagiye Depression", it lies at approximately 132 meters (about 433 feet) below sea level, and is the lowest point in the former USSR.
