This document discusses the different ways that lakes are formed, including through tectonic activity, glaciation, volcanic activity, erosion, deposition, and human/biological activities. Some key lake formations mentioned are rift valley lakes like Tanganyka formed by tectonic movement, cirque lakes in mountainous regions formed by glacial erosion, caldera lakes formed in volcanic craters, and man-made lakes like Lake Mead created by dams on rivers. The document provides many examples of specific lakes that illustrate each formation type.
