How was Lake Baikal formed? Why do you account for 20 of the world s freshwater?

The reasons for its formation are, first of all, the great tectonic plate movements that occurred on the earth and the general environment of glaciers a long time ago; The second is the great separation of the bay from the sea, the inflow of perennial rain and fresh water.

The cold climate reduces the evaporation rate and volume of the lake's water; At the same time, the depth of the rift valley is incomparable to that of many lakes, which significantly increases the water storage capacity of Lake Baikal, so it is not surprising that it accounts for 20% of the world's fresh water.

Lake Baikal slowly evolved into a huge lake due to changes in the earth's crust, depressions formed by land cracks, and the inflow of stagnant water and fresh water. It is located at the junction of the Eurasian and Amur plates. In addition, the frequent movement of these two tectonic plates has caused Lake Baikal to grow from a relatively small pit to a deeper and larger one, and with tens of thousands of years of fresh water, it has become so large and still expanding.

There are many lakes in the world that are larger than that, but they do not have as much freshwater as they are, because they do not have the depth of Baikal, which eventually makes it the largest freshwater lake in the world.

Lake Baikal is located in Russia, and Lake Baikal was previously formed by the movement of the earth's crust, and then the inflow of its own water and fresh water formed a freshwater lake, and later due to the frequent "movement" of the Eurasian and Amur plates, the lake became larger and larger.

Lake Baikal (Russian: English: Lake Baikal), located in the south of Eastern Siberia, Russia, 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, the total volume of the lake is one trillion cubic meters, the deepest depth is 1637 meters, it is the world's deepest lake, the largest freshwater lake in Eurasia, the tiger is 636 meters long, the average width is 48 kilometers, the area is 10,000 square kilometers, formed by the fault and collapse of the strata, With an altitude of 455 meters above sea level and an average depth of 730 meters, the lake is the largest freshwater lake in Eurasia and the deepest lake in the world.

Lake Baikal was a Chinese lake during the Han Dynasty, then called Beihai, and during the Han and Wei and Jin dynasties, it was the range of activities of the Xiongnu and Xianbei people. In the heyday of the Tang Empire, Lake Baikal belonged directly to the Tang Empire, and later was controlled by the Turks and Uighurs respectively. From the beginning of the Song Dynasty to the Ming Dynasty, this time it was the sphere of activity of the Mongols, and during the Qing Dynasty, it was included in the territory of the Qing Empire.

Because the Qing Empire was still at war with the Dzungar Khanate at that time, in exchange for the neutrality of Tsarist Russia, Baikal was voluntarily abandoned to Tsarist Russia.

During the Kangxi period, the Qing Empire and Tsarist Russia signed the Treaty of Nebuchu, which officially assigned the area of Lake Baikal to Tsarist Russia, and since then the Central Plains Dynasty and Lake Baikal have no relationship. Lake Baikal is the deepest lake in the world and the largest freshwater reservoir on the planet, accounting for 20% of the world's freshwater.

Lake Baikal is the largest and deepest freshwater lake in the world and is known as the "Blue Eye of Siberia". The lake shape is long and narrow, like a crescent moon, so it is also called "Moon Lake". The water of Lake Baikal is clear, stable and transparent, and it is the second most transparent in the world.

It was inscribed on the UNESCO World Heritage List in 1996.

Lake Baikal is located in Russia and belongs to the North Asian region, and it is also the deepest and largest lake in the world.

Lake Baikal is located in the south of Eastern Siberia and is located on the territory of the Republic of Buryatia and the Irkutsk region.

It is located in the Russian region, Lake Baikal is located in the southern part of Eastern Siberia in Russia.

As follows, Lake Baikal contains a large amount of fresh water and unique biological species, is known as the Qiaozhou Blue Bright Chain Qizhu and Natural History Museum, and is also an important ecological reserve and tourist attraction, because of its beauty and uniqueness, Baikal is listed as a UNESCO World Heritage Site, a reserve of biological filial piety and a Ramsar wetland. <>

Lake Baikal, located in the Siberian region of Russia, is the largest freshwater lake in the world and one of the oldest, deepest, clearest and largest freshwater lakes in the world. Lake Baikal, with its vast surface and huge volume of water, is known as the "Blue Pearl" and "the last pure land of the world", and is a wonder of nature.

Geographical features of Lake Baikal.

Lake Baikal is 636 km long and 79 km wide, covering an area of more than 31,000 square kilometres, which is equivalent to the total area of Belgium or Malta. The lake alone contains 20% of the world's freshwater reserves, enough to feed the world's population for a century. Calling acres of stuffiness.

With a maximum depth of more than 1,600 meters, Lake Baikal is the deepest freshwater lake on Earth. The blue oxygen-rich rocks at the bottom of the lake are among the oldest rocks on Earth. The water of the lake is highly transparent, and you can see the stones and bright aquatic plants at the bottom of the lake.

The lake is well-lit and looks extraordinarily peaceful and mysterious.

Ecological environment of Lake Baikal.

Lake Baikal is one of the cleanest freshwater lakes in the world and is blessed with rare freshwater biological resources. The lake is home to more than 3,000 species of plants and animals, of which 2,000 are unique to the lake. The water in the lake is crystal clear, with a transparency of up to 40 meters, which is enough to see the strange sight of the bottom of the lake.

However, in recent years, with the continuous improvement of people's living standards, it has also brought certain ecological problems. In order to protect the ecological environment of Lake Baikal, Russia** has taken a series of strong measures, such as restricting tourism development, banning the operation of drifting boats, prohibiting aquaculture on the lake's shores and establishing industrial zones. These measures contribute to the preservation of the ecological balance of Lake Baikal and the continued health of its ecological environment.

Conclusion Lake Baikal is rich in natural resources and ecological ecology, and is one of the most beautiful and mysterious places on the planet. It is the responsibility and obligation of all mankind to protect the ecological balance of Lake Baikal and maintain the health of its natural environment. We should always pay attention to the natural environment and ecological problems of Lake Baikal and do everything we can to protect the ecological balance of Lake Baikal.
