Caspian Sea - the largest lake in the world

Caspian Sea - the largest lake in the world, the longest lake, the only lake with a length of more than 1000km

The Caspian Sea is located in the hinterland of the Eurasian continent, between Asia and Europe, with an area of ??approximately 380,000 square meters and an average water depth of 180m. It is the largest lake in the world. The Caspian Sea is slightly smaller than the area of ??Yunnan Province in China (39.4k㎡) and slightly larger than the area of ??Japan (37.8k㎡). Its size is almost 10 times that of the Sea of ??Azov. It has almost reached the size of the Baltic Sea.

The Caspian Sea is long and narrow from north to south, slightly S-shaped. Its width from east to west is about 320km, and its length from north to south is about 1,200km. It is the longest lake in the world and the only lake with a length of more than 1,000km. How to describe it? The straight-line distance from Beijing to Shanghai is only 1050km. Therefore, the length of the Caspian Sea from north to south is equivalent to the mileage of driving from Beijing to Shanghai.

The Caspian Sea is an inland lake that was once connected with the Black Sea and the Mediterranean Sea. Later, it became independent due to crustal movement, forming the current huge lake. Because there are many rivers flowing into the Caspian Sea, the salinity of its lake water also varies greatly. It reaches about 2 parts per thousand in the north and as high as 13 parts per thousand in the south.

Whether the Caspian Sea is a sea is still controversial. Chinese people basically think it is a lake, while some people in this country think it is a sea. They also demonstrated some evidence, such as the existence of marine animals such as seals in the Caspian Sea. The Caspian Sea is not a lake unique to any country. Its northeastern and western sides belong to Turkmenistan, Kazakhstan, Russia and Azerbaijan respectively, and its southern coast is in Iran. Therefore, it is normal for there to be disputes. After all, if it is defined as a sea, it will be complicated. . It will involve many issues such as the high seas. If it is defined as a lake, there won't be so much trouble.

A lake is a depression on land, a body of water formed by accumulated water, or a relatively wide body of water with slow flow. Hundreds of millions of years of earth's tectonic movements and glaciers, as well as geological processes such as river erosion and siltation, have formed many depressions and accumulated water into lakes. Although the ecological environment of the Caspian Sea is similar to that of the sea, it is not directly connected to the sea after all. It is an independent body of water and fully meets the definition of a lake. Therefore it is the largest saltwater lake in the world.

Today’s Caspian Sea is rich in mineral resources, water resources, fishery resources, and tourism resources. In short, this is a gift of nature's love for mankind.
