Looking at a map, on all continents, you can see the lake. Some of them elongated, others rounded. Some lakes are located in mountainous areas, others on vast flat plains, some very deep and some very shallow. The shape and depth of the lake depend on the size of the basin which it occupies. Lake basins are formed by different ways.
Most of the major lakes of the globe is of tectonic origin. They are located in major deformations of the earth crust in the plains or fill the deep tectonic crack — rift (lake Baikal, Tanganyika, Nyasa, etc.).
Lake basins can become craters and calderas of extinct volcanoes, and sometimes depressions on the surface of lava flows. These lakes are called volcanic, are found, for example, on the Kuril and Japanese Islands, in Kamchatka, on the island of Java and in other volcanic regions of the Earth. It happens that the lava and fragments of igneous rocks dammed the river valley in this case also there is a volcanic lake.
