Is it possible to be below sea level

The dry climate offers very little rain and very high evaporation. This excess of evaporation over precipitation prevents the depression from filling with water. The photo above shows salt deposits of the Dead Sea - a product of high evaporation rate. Some below-sea-level depressions are dry, most others have salt lakes.

The lakes are undrained, which means water flows in but does not flow out. Since water cannot flow up hill, the lakes cannot empty into the sea like most do and so they accumulate salt halite as their waters evaporate.

Where does the salt originate? Some of it comes from ancient sea floor salt deposits that have been uplifted then weather and release the salt which reaches the depressions via rivers. Many other rocks weather to yield sodium and chlorine ions that are carried to the lake by rivers.

Owing to variations in rainfall, evaporation rates, and human water use, most of the lake levels fluctuate from year to year. Some have come and gone in historic times. The present Salton Sea California, USA was produced by a canal construction accident in , though the lake has come and gone naturally many times in the last thousand years. New Orleans is a city below sea level. It is protected from flooding by seawalls and an extensive groundwater pumping system. The lowest exposed land on Earth is at the Dead Sea shore, at meters.

The deepest lake bottom in a below-sea-level depression also belongs to the Dead Sea at meters. Lake Baikal in Russia is at an elevation of meters, but with a maximum depth of meters, its bottom lies at meters.

The Bentley Subglacial Trench in Antarctica reaches meters below sea level. It is the lowest point on Earth that is not covered by ocean, although it is covered by ice. The trench is huge, roughly the size of Mexico. The deepest point on the ocean floors is , meters in the Mariana Trench.

Trenches are the upper most parts of subduction zones and there are dozens of trench locations that are more than meters below sea level. But sea level varies and during the Great Ice Age 18, years ago, sea level was meters lower. Today, large areas are under water that during the Great Ice Age were well above sea level. It is also likely that long ago and far into the future, plate tectonics will produce higher mountains and deeper trenches and depressions than we have today. The Dead Sea Depression is an extensive area of land that is below sea level.

The Caspian Depression encompasses the northern part of the Caspian sea. The deepest point of this huge depression lies in a karst trench on the eastern side of the Caspian Sea in Kazakhstan. The low point, Karigiye, is feet meters below sea level.

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 maximum depth below sea level reaches feet meters. An endorheic basin, the Qattara Depression is very dry but supports oases, of which the most famous are Siwa and Cana, both inhabited.

Salt pans, dunes, and bizarre wind-eroded rocks are common in the Qattara Depression. Formed by a fault, this depression is huge and expansive and is surrounded by some of the tallest mountains on earth, notably the Tian Shan and Bogda Shan.

The region has a storied history and the ruins found throughout the basin are attributed to the Silk Road route that ran through here 2, years ago. A crossroads of cultures, some of the historic and archeological sites in the region include the Bezeklik Thousand Buddha Caves, the Gaochang Ruins, and the Astana-Karakhoja ancient tombs. Lake Assal is at the bottom of a crater lake which lies feet 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 Ethiopia where the Danakil Depression has a low elevation of feet meters below sea level. Sitting between Israel and Jordan, the Dead Sea is incredibly saline, at While the Dead Sea is considered a hypersaline, endorheic body of water, the Sea of Galilee has both an inflow and outflow provided by the Jordan River. The two bodies of water can hardly be more of a contrast. Occupying the Jordan Rift Valley, the Dead Sea is a stark, forbidding landscape seemingly barren of life, whereas the Sea of Galilee, true to its biblical roots, is life-giving, with leafy shores now occupied by dozens of resort hotels which sit adjacent to fertile groves of fruit orchards.

Travel Destinations. Fortunately, the anti-flooding system will keep everything dry for you when you make your trip! Is the Netherlands below sea level? Afsluitdijk in the Netherlands Well, yes. Other cool things to see in the Netherlands Aside from the cutting edge ways of preventing flooding, the Netherlands offers some truly world-class tourism attractions.
