Question

Почему в тундре много болот и озер?

Answer 1

Земля не оттаивает даже летом, а верхняя часть льда/снега всё-таки тает... и вода не уходит, а "стоит" болотами и озёрами.

Answer 2

Why are there many swamps and lakes in the tundra?

The presence of swamps and lakes in the tundra can be attributed to several factors.

1. Permafrost: The tundra is characterized by permafrost, which is a layer of permanently frozen soil. The top layer of permafrost thaws during the summer months, creating a layer of waterlogged soil. This waterlogged soil contributes to the formation of swamps and lakes.

2. Poor Drainage: The tundra has a high water table and poor drainage due to the frozen ground. The frozen soil acts as a barrier, preventing water from infiltrating deeper into the ground. As a result, water accumulates on the surface, forming swamps and lakes.

3. Melting Snow and Ice: During the summer months, the tundra experiences a period of thawing. This thawing process leads to the melting of snow and ice, which further contributes to the formation of swamps and lakes.

4. Depressions and Low-lying Areas: The tundra landscape is characterized by depressions and low-lying areas. These depressions act as natural basins, collecting water and forming swamps and lakes.

In summary, the presence of swamps and lakes in the tundra can be attributed to factors such as permafrost, poor drainage, melting snow and ice, and the presence of depressions and low-lying areas
