11,000 metres
- Only around 20% of the ocean floor has been mapped to modern standards. That includes Challenger Deep in the Mariana Trench near Guam, which at around 11,000 metres below sea level is the deepest known point on the planet.

At 36,070 feet (10,994 meters) below sea level, Challenger Deep in the Pacific Ocean’s Mariana Trench is the ocean’s deepest known point. (The graphic below contrasts relative ocean depth with the sizes of various locations, structures, and feats.)
Fully natural places below sea level require a dry climate; otherwise, rain would exceed evaporation and fill the area. All figures are in meters below mean sea level (as locally defined), arranged by depth, lowest first:

It may sound counterintuitive, but our planet has a number of dry patches of land which occur below 0 feet—or mean sea level. The origins of these areas, 10 of which are featured below, are mostly the result of two geological and geographical phenomena. The first is arift valley, or an area on the surface of the Earth which is being split or rent a...
Western Europe’s two lowest points are split between two areas in Denmarkand the Netherlands, each 23 feet (7 meters) below sea level. Unlike the other areas on this page, both low points are the result of human-induced land drainage. The polders in the Netherlands are areas that were reclaimed from the sea by the Dutch in the 13th century. The lan...
Lake Eyre is the continent’s lowest point at 49 feet (15 meters) below sea level. Occasionally, this basin will fill with water, temporarily turning it into Australia’s largest lake, but the occasion is very rare (only about four times each century!). Most of the time, the Lake Eyre Basin in South Australia is filled with a salt pan. Having no outl...
The Salton Sea sits in a graben in the Southern California desert, submerging part of the otherwise exposed San Andreas rift zone between two continental plates (not unlike the Dead Sea rift zone between Israel and Jordan, the lowest spot on earth—but more about that later!). The Salton Sea is 234 feet (71.3 meters) below sea level and is a saline ...
This is the lowest, driest, and hottest place in North America. The ancient lakebed that serves as the floor of this graben is 282 feet (86 meters) below sea level, and the lowest point is known as ‘Badwater.’ Death Valley, like many other deep valleys in the same region, is the result of a block of the Earth’s crust sinking as the ‘skin’ gets stre...
Within Argentina are all of the significant areas in South America that are below sea level: Laguna del Carbon, Bajo del Gualicho, Salina Grande, and Salina Chica. Among them is the lowest place in the southern and western hemispheres—the Laguna del Carbon—which bottoms out at -344 feet (-105 meters). All three areas are located in the southern pro...
The Caspian Sea is the largest enclosed body of water in the world, and its shore is 92 feet (28 meters) below sea level. It sits at the bottom of the largest area in the world below sea level, straddling the borders of Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. It’s a salt lake and considered endorheic, having no natural outflow. The ...
Africa is home to the largest number of places below sea level in the world, and North Africa has the most locations within the continent. The Qattara Depression in Egypt’s Libyan Desert, Africa’s second-lowest point, is a huge area covering over 7,000 square miles of land; it averages close to 200 feet (70 meters) below sea level. The maximum dept...
This trough is the Earth’s third-lowest point, reaching a depth of 505 feet (154 meters) below sea level. Located in China’s western desert region south of Mongolia, the Turpan Depression is the country’s hottest and driest area. Formed by a fault, this depression is huge and expansive and is surrounded by some of the tallest mountains on earth, no...
Lake Assal is at the bottom of a crater lake which lies 509 feet (155 meters) below sea level, making it the second-lowest point on earth after the Dead Sea rift zone. The larger region, known as the Afar Depression, extends into Ethiopiawhere the Danakil Depression has a low elevation of 410 feet (125 meters) below sea level. National Geographic d...
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [1][2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3] The deep sea is considered the least ...
The very deepest depth of the ocean is roughly 2,000 meters deeper than Mount Everest is tall—36,070 feet deep (10,994 m)! Each zone has a different mix of species adapted to its specific light level, pressure, temperature, and community. About three-fourths of the area covered by ocean is deep, permanently dark, and cold. This is the deep sea.
Nov 29, 2023 · Yes, the Mariana Trench is the deepest part of the ocean. Its deepest point, known as the Challenger Deep, reaches approximately 10,984 meters (36,037 feet) below sea level, making it the deepest known point on Earth.
