Glaciation. Artwork showing features of a glacier as it retreats. A glacier is formed when snow from high ground flows downhill under its own weight. A glacier retreats when the ice melts faster than the glacier moves forward. Distinctive landscape features are created by the weight of the ice, the meltwater, and the erosion by ice and meltwater. Seen here are: glacial lakes and rivers; erratics (isolated boulders, centre left); eroded bedrock mounds (lower right); various moraine features (lateral moraine is the dark bands on the glacier, terminal moraine forms semicircular ridges at each retreat/advance stage); and a cirque (bowl-shaped hollow carved in the mountains, upper right).
