What types of lake basins are distinguished?

1) Tectonic – formed in the depressions of the earth’s crust on the plains, in the troughs in the mountains, in the foothill depressions and in the rift depressions. As a rule, they are large in area and deep.

2) Volcanic – formed in craters and calderas of extinct volcanoes, in lava depressions and maars.

3) Meteorite – formed in depressions, from falling meteorites.

4) Glacial – their occurrence is associated with the activity of glaciers. They are usually in the direction of movement of the glacier. The same group includes tar and trough lakes. Karovs arose in quads and circuses – niche-like depressions on the upper slopes of mountains, and troughs – in trough valleys.

5) Failure – lakes, the basins of which have arisen as a result of leaching of soils and rocks by surface and mainly groundwater. failed lakes include: karst, suffusion and thermokarst lakes. The lakes are oval in shape, the shores are scarce and not deep.

6) Aeolian – lakes that have arisen in blowing hollows, as well as between dunes and dunes. They are small and not deep.

7) Underwater lakes – the emergence of these lakes is associated with rock falls, landslides blocking river valleys, damming rivers with lava flows, and glacier moraines.

8) Organogenic – bog lakes and lagoon lakes among coral buildings.
