Quick Summary
Tectonic lakes are bodies of water formed by movements of the Earth's crust, a process known as tectonism. These movements can create depressions in the Earth's surface that fill with water. Examples include basins formed by faulting, such as those holding Lake Tahoe and Lake Baikal, or by the uplift of the ocean floor, like Lake Okeechobee. Some large inland seas, like the Caspian Sea, also originated from tectonic activity that isolated vast bodies of water.12
