Lake – a mass of water or other liquid of considerable size, situated on the land. The large number of lakes on Earth is freshwater, and most lie in the Northern hemisphere at higher latitudes. In the ecology of the surrounding lake environment is referred to as lacustrine deposits. Large lakes are sometimes referred to as “inland seas” and small seas are sometimes referred to as lakes. Small lakes tend to put the word “lake” after the name, as in Green Lake, while larger lakes often invert the word order, as in Lake Ontario, at least in North America.
Most lakes have a natural outflow in the form of a river or stream, but some have not, and lose water solely by evaporation and/or underground leakage. They are called internal lakes.
The term “lake” is also used to describe such a feature as lake Eyre, which is a dry basin most of the time, but can be filled with seasonal heavy rains.
Many lakes are artificial and constructed for hydro-electric power, regional purposes, industrial use, agricultural use or domestic water supply.
Evidence of extraterrestrial lakes exists. The testimony of lakes filled with methane, was approved by NASA to return the automatic research station “Cassini” – observing satellite Titan, which moves around the planet Saturn.

The Baikal region is located in the South-East of Russia within the mountain belt of South Siberia.

A new special protection area, which area is 140 thousand hectares and includes a lake Elgygytgyn and the surrounding area, appeared in Chukotka. According to the Chairman of the Committee of natural resources and environment district Olga Safonova, this will allow you to save the largest freshwater reservoir in North-East Asia in its original form.
Lake Elgygytgyn, located on the boundary of the Anadyr and Chaunsky districts, is unique in its origin. According to scientists, it was formed about 3.5 million years ago during the late Pliocene period.
— There are two main hypotheses about the origin of the basin of the lake – “endogenous” and “meteor”. The latter is confirmed by the almost perfectly round shape of the pit and a large depth, which reaches 169 meters, ” said Olga Safonova.
She noted that at the lake, the diameter of which is 11.5 km, and the area of a water mirror – 117 square kilometers, there are almost no sources and tributaries, which occurs in slow water circulation.
– Besides, Elgygytgyn Continue reading
