Tectonic lakes are formed as a result of tectonic activity, where movements of the Earth’s crust create depressions or basins. These geological processes occur due to the shifting of tectonic plates, which can cause rift valleys or subsidence. Over time, these depressions collect water from precipitation, rivers, or groundwater, leading to the formation of lakes. Examples of tectonic lakes include Lake Baikal in Siberia and the African Great Lakes. Their unique geological origins contribute to distinct ecosystems and biodiversity, making them vital for both environmental studies and local communities that rely on these water bodies for resources and recreation.
