More of the worldâs lakes were formed by glaciers than by any other method. During the Ice Age, much of the Northern Hemisphere was covered with great glaciers that cut or enlarged depressions in the earth which later filled with water. These are called glacial lakes.
How do volcanoes form? Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface.
