Lake Baikal is so deep than other lakes, why is it so deep?

The deepest lake in the world is Lake Baikal, this very narrow lake has an average depth of 730 meters, the deepest depth is 1637 meters, its area is 10,000 square kilometers, ranking seventh in the largest lake area in the world, but because it is deep enough, it is also the largest lake in the world in terms of freshwater reserves, with a storage capacity of trillions of cubic meters, which is equivalent to the total water storage of the Great Lakes region of the United States, accounting for about 1 5 of the world's surface flowing freshwater reserves, and more than 8 times the total surface freshwater in China.

The reason why Lake Baikal is so deep is because it is a stratigraphic tectonic fault lake, that is to say, it is formed by the movement and fault of the earth's crust, and it is a **fault collapse type lake, and scientific geologists believe that it first began to form 25 million years ago, and it was formed in several huge **, about 20 million years ago, its main outline was formed, but until today, this area still occurs more than 2,000 times a year, and it is no exaggeration to say that Baikal is also ** Such geological activity shook out a large lake.

In the early days, Lake Baikal was much deeper than it is now, geologists found that the thickness of the sediment under the water of Lake Baikal today exceeded 8 kilometers, indicating that the depth of Lake Baikal was once close to 10,000 meters, which is about the same as the Mariana Trench, and this depth is far greater than that of other lakes in the world, and the depth of the existing Lake Baikal is only equivalent to its earlier depth of 1 6, and later through the continuous filling of sediments such as sediment, the depth of Lake Baikal has become shallower, and after more than 20 million years of landfilling, today its deepest depth is only 1,637 meters. But even so, it is still the deepest lake in the world, and if you put our Tarzan in Lake Baikal, its summit is still about 100 meters above the water.

Today, the vegetation in the Baikal basin is relatively good, the rivers in it contain less sediment, so the water is very clear, the sun shines directly 17 meters below the surface, and the water quality meets the drinking water standards, so that humans can drink it directly.

There are also some marine creatures living in Lake Baikal, such as seals, sponges, conchs, lobsters, Omur fish, etc., about them ** is still a mystery, some people believe that they came up here along the Yenisei River, but others believe that ancient Baikal was once part of the ocean, and then the ocean receded, and some marine life survived in Baikal.

Historically, Lake Baikal has long been under the jurisdiction of certain regimes in our country, and its names are quite numerous, such as Beihai, Yusini Dashui, Xiaohai, Baihar Sea, and Lake Baihail.

Probably because of the movement of the earth's crust many years ago, Baikal is much deeper than other lakes

The depth of the lake is as high as 5,000 meters, because the lake is at a very low altitude, surrounded by high mountains, and has a special geographical environment and abundant water sources, so that the depth of the lake exceeds 5,000 meters.

It is related to the movement of the Earth's tectonic plates. Because the movement of the plates will make it deeper and deeper.

Lake BaikalThe average water depth is 730 meters, and the maximum depth is 1,637 meters.

Lake Baikal, also known as the deepest lake in the world, is also the largest freshwater lake in Eurasia.

The deepest part of Lake Baikal is 1,637 meters, the average depth is 730 meters, the total length of the lake is 636 kilometers, and the total area is 10,000 square kilometers.

Russian scientists in July 2008 proposed to conduct a submarine.

Survey compendium, seeking to dive into the depths of Lake Baikal. To this day, the deepest part of the lake remains undetectable.

Geomorphological features:Geologically, Lake Baikal is a recess of a faulted valley, a large rift that goes 15 to a depth of 15 20 kilometers. Lake Baikal and its catchment area are a unique geological system in the world.

Lake BaikalThe average water depth is 730 meters deep.

The deepest point is 1,637 meters, and its area is 10,000 square kilometers.

It ranks seventh in the world in terms of lake area, but because it is deep enough, it is also the largest lake in the world in terms of freshwater reserves, with trillions of cubic meters of water, compared to the Great Lakes of the United States.

The total water storage in the region is comparable, accounting for about 1.5 of the world's surface flowing freshwater reserves, and more than 8 times the total surface freshwater in China.

Biological resources

The forest tree species of the Baikal region are dominated by pineaceae, larch genus.

Plants, in the Baikal region are Siberian larch, pine, and in the pine forests of the Baikal region are dominated by Siberian Korean pine and Scots pine. The vegetation in the Baikal region is typical of temperate forest-steppe vegetation, but there are obvious geographical differences in the distribution of different vegetation types.

The vegetation of the area is dominated by taiga with forest cover.

Up to 70%, distributed between 500 and 1100 meters above sea level, the dominant tree species are Siberian larch, Siberian Korean pine and European scots pine, and at the same altitude, there are P. chinensis meadows dominated by needle grass and fescue.

With increasing altitude, subalpine meadows and montane tundra appear, while in the coastal zone of lakes and lakes between Baikal or forest meadows, plants of the sedges, ranunculaceae and rosaceae are present.

It is mainly a swamp meadow, and in the lake water body, it is mainly aquatic vegetation with eyelid, buttercup and black triangular water.

The deepest point of Lake Baikal is 1637 m (2015).

Located in the south of Eastern Siberia, Russia, Lake Beshchenlugar is the world's largest and deepest freshwater lake, located in the territory of the Republic of Buryatia and the Irkutsk region, between 51°29 north latitude and 55°46 north latitude and 103°41 -109°57 east longitude.

Lake Baikal is long and narrow, trending northeast and southwest, only 111 kilometers away from the Mongolian border, the lake is 636 kilometers long, the average width is 48 kilometers, the widest kilometer, the area is 10,000 square kilometers, the average depth is 744 meters, the deepest point is 1637 meters, the elevation of the lake is 456 meters, the shape is crescent-shaped, and the total water storage is trillions of cubic meters.

1. The deepest lake in the world is Lake Baikal.

2. Lake Baikal, located in the south of Eastern Siberia, in the territory of the Republic of Buryatia and Irkutsk Oblast, between 51°29 55°46 north latitude and 103°41 109°57 east longitude, with a total volume of trillion cubic meters (2015) and a maximum depth of 1637 meters (2015), is the world's deepest lake and the largest freshwater lake in Eurasia. The lake is 636 kilometers long, 48 kilometers wide on average, 10,000 square kilometers in area, formed by strata fault collapse, 455 meters above sea level, and 730 meters in average water depth.

3. Lake Baikal was known as the Beihai in ancient China and was known as the "Pearl of Siberia", and in 1996, UNESCO registered Baikal as a World Natural Heritage Site.

4. Lake Baikal is injected by 336 large and small rivers, including the Selenga River, with a catchment area of 10,000 square kilometers. The Angara River, a tributary of the Yenisei River, flows from this point, and there are 27 small islands in the lake, which are not covered by Quaternary glaciers, and still retain freshwater animals from the Tertiary period, such as Baikal seals, whitefish, Omul fish, sharks, etc. The lake is an important fishing ground in Siberia and has a great influence on the climate of the region.

Lake Baikal is the deepest and largest freshwater lake in the world. It is located on the territory of the Republic of Buryatiya and the Irkutsk region. The lake shape is long and narrow, like a crescent moon, so it is also called "Moon Lake".

It is 636 kilometers long, 48 kilometers wide on average, 10,000 kilometers wide at its widest, 10,000 square kilometers in area, 744 meters in average depth, 1,680 meters in depth at its deepest point, and 456 meters above sea level.

The deepest point of Lake Baikal is 1620 meters.

Lake Baikal is long and narrow, like a crescent moon, so it is also called "Moon Lake". It has a total length of 636 kilometers, an average width of 48 kilometers, the widest kilometer, an area of 10,000 square kilometers, an average depth of 744 meters, the deepest point of 1,642 meters, and an elevation of 456 meters above sea level. The water of Lake Baikal is clear and stable and transparent (the second most transparent in the world.

Its total water storage capacity is 23,600 cubic kilometers, which is equivalent to the total water storage capacity of the Great Lakes of North America, accounting for about 1.5 of the total surface unfrozen freshwater resources. Suppose that Lake Baikal is the only source of water in the world, it will have enough water for 5 billion people for half a century. Lake Baikal is the ninth largest lake in the world in terms of area, but it is one of the oldest lakes in the world (it is estimated to be 25 million years old).

The secret of the huge volume of Lake Baikal is also the depth, which has an average depth of 730 meters and a maximum depth of 1,620 meters. If the four tallest buildings in the world are stacked one on top of the other at the deepest point of the bottom of the lake, the TV mast on the roof of the fourth building is still 58 meters below the surface of the lake, and if we put the tall Tarzan into the deepest part of the lake, the top of the mountain is still 100 meters above the water.

The waters of Lake Baikal are crystal clear.
