A lake is a lake basin and the body of water it holds. A lake basin is a relatively closed natural depression on the surface that can store water. The source of lake water is precipitation, surface runoff, groundwater, and some come from ice and snow meltwater.

The consumption of lake water is mainly evaporation, seepage, excretion and development and utilization.

The total area of ​​lakes on the earth is 2.7 million square kilometers, accounting for 1.8% of the land area. There are 35 lakes with an area of ​​more than 5,000 square kilometers.

Finland has the most lakes and is known as the "Land of Ten Thousand Lakes", with more than 60,000 lakes of various sizes.

The lake is rich in fish, shrimp, crab, shell, etc. It is an important source of raw materials for aquatic products and light industry. The unreasonable development of lake resources will lead to the reduction of lake fishery resources, the reduction of lake area and the swamp of the land around the lake.

Have you seen these lakes? They have their own characteristics.

1. The Caspian Sea.

In terms of water storage capacity, the lake is the fourth largest lake in the world with a coastline of 3,000 kilometers, dense forests along the coast, and numerous lakes and bays on the north bank.

Lake water is an important part of global water resources. Lake water can be continuously renewed. The renewal period of different lakes varies. The length of lake water replacement period depends on its volume and annual runoff into and out of the lake.

For the ecological environment of the earth, lake water resources are also the objects we need to protect.

The beauty that nature brings to us is different, and the lake is one of them.
