The total amount of water on the planet is staggering, but among the many water resources, freshwater resources are very scarce, accounting for only 1% of the total water.
Lakes and rivers account for the largest share of this 1% of freshwater resources, which are the main reservoirs of freshwater resources on Earth.
Among the many freshwater lakes, the most famous is Lake Baikal in Russia, which is not only the largest lake in the world, but also the oldest lake in the world.
Lake Baikal has a huge amount of water that can meet the drinking water needs of the world's 5 billion people for 50 years, but also for 50 years.
Because of the huge amount of water stored in Lake Baikal, it is also called "the super-reservoir of the earth", so how much water is there in Baikal?
What kind of rich ecological environment is there?
But it is also threatened by water pollution and falling water levels.
So in order to better protect the world's largest freshwater lake, let's explore it together!
1. The largest lake in the world.
The earth has an abundance of water, but the vast majority of it is salt water from the oceans, and freshwater resources are very scarce, accounting for only 1% of the total water.
Lakes and rivers account for the largest share of the 1% of freshwater resources, which are the main reservoirs of freshwater resources on Earth, and the amount of water stored in lakes is much larger than the amount of water stored in rivers.
Among the many freshwater lakes on the planet, Lake Baikal has the largest water storage volume, which is the largest freshwater lake in the world and the largest freshwater lake.
Lake Baikal is located in the Siberian region of Russia, and its southeastern part is the border of Mongolia.
Lake Baikal is a very wide lake, with an area of more than 32,000 square kilometers, which is larger than the mainland province of Jiangxi.
It is also the largest lake in the world in terms of length, with a length of about 636 kilometers, which is equivalent to Hunan Province on the mainland.
In terms of the depth of the lake, it is also the largest in the world, and its deepest depth reaches 1.6 kilometers, which is deeper than the Three Gorges of the Yangtze River on the mainland.
The fact that the lake has such a huge surface and depth also gives Baikal a huge water storage.
Lake Baikal has a huge amount of water stored in it than all the freshwater resources of the continent.
According to statistics, Lake Baikal has a storage capacity of 23.1 trillion cubic meters, which is huge, enough to provide drinking water for 5 billion people in the world for 50 years.
Moreover, the water resources in Lake Baikal are very clear, the water quality is very good, there is no pollution, and it is a very suitable resource for drinking water for human beings.
But as the world's largest freshwater lake, Lake Baikal has much more than that, and it can supply drinking water for 5 billion people for 50 years.
2. The geological structure of Lake Baikal.
The geological structure of Lake Baikal is very complex.
Formed by the eruption of a huge volcano in the past, it is also the oldest lake in the world, older than the Yangtze River on the mainland.
Lake Baikal is located in the rift zone of the Siberian Shield, which is full of intense volcanic activity, and the huge volcanic activity also floods some of the lava erupted from the crater, forming a huge basin.
Later, with the constant inflow of water into the basin, a huge lake was formed, and this lake was called Lake Baikal.
Lake Baikal is located in a cold zone, and the amount of water in the lake mainly comes from snow and rainfall, which gives Baikal a powerful water replenishment system.
The geological structure of Lake Baikal is very complex, bottomless, and there are numerous tributaries, among which there are numerous springs that come from the ground, so the lake has a very powerful water supply system.
In the geological structure of the lake, there are many cracks, which are caused by the tectonic movement of the earth's plates, and many cracks are formed due to the compression and pull of the plates.
These cracks allow the amount of water in the lake to penetrate into the cracks and enter the ground, thus reducing the amount of water in the lake.
However, the amount of water in Lake Baikal does not decrease as a result, because the lake continuously absorbs water from its tributaries, thus replenishing the lake's volume.
3. Water quality of Lake Baikal.
The water of Lake Baikal is very clear, the surface of the lake is rippling, the water is clear and transparent, and the aquatic plants in the lake are also very clear, which is also because the aquatic plants in the lake are very clear, so the lake water will appear very clear.
The water of the lake is very transparent, you can see stones dozens of meters away, and the water is very rich in aquatic plants, which are also a precious resource in Lake Baikal.
These aquatic plants can not only purify the water quality in the lake water, but also absorb harmful substances in the lake water, effectively purify the lake water, and keep the lake water clean.
The water of Lake Baikal is very clear because of the important role played by the aquatic weeds in the lake, which also prevent sediment from settling down and change the transparency of the water.
However, despite the clarity of the water on Lake Baikal, the water quality in the lake changes with the seasons and the temperature, from the clearest in summer to turbid in winter.
However, although the quality of the water in the lake changes with the seasons, the water quality of the lake is still very high quality and suitable for human consumption.
The amount of water in Lake Baikal is very large, but the water resources around Lake Baikal are very scarce, which makes Baikal even more special, as the largest freshwater lake in the world, Baikal has huge water resources and abundant aquatic resources.
Lake Baikal is surrounded by a beautiful ecological environment, with a large number of rare flora and fauna, and a rich diversity of species.
On the surface of Lake Baikal there are many glaciers, and there are also numerous rivers that flow into Baikal, forming patches of water.
The numerous waters form a rich ecological environment, where many aquatic animals and plants live, these creatures are also very precious, they can not only enrich the diversity of organisms, but also provide many cases for human scientific research.
Lake Baikal is also surrounded by many forests, which cover the perimeter of the lake, which not only provide the lake with numerous water sources, but also maintain the water quality of the lake.
epilogue
Lake Baikal is the largest freshwater lake in the world, with a huge water reserve, and is a natural wonder of Russia, loved by people all over the world.
However, with the continuous development of human activities, environmental pollution and overexploitation of resources, the water level of Lake Baikal has been declining year by year, and the ecological environment has been greatly threatened, so people should work together to better protect Lake Baikal, the largest freshwater lake in the world.
