sivukerroksia

Sivukerroksia, also known as lateral moraines, are geological features formed by the accumulation of debris along the sides of a glacier. These moraines are distinct from medial moraines, which form at the junction of two glaciers, and terminal moraines, which mark the furthest extent of a glacier. Lateral moraines are typically composed of a mix of rock, soil, and other glacial debris, which is pushed aside by the advancing glacier. The debris is then deposited along the sides of the glacier as it retreats, creating a ridge-like structure. These features are important indicators of past glacial activity and can provide valuable information about the movement and behavior of glaciers. Lateral moraines are commonly found in areas with significant glacial history, such as the Alps, the Himalayas, and the Arctic. They play a crucial role in understanding the dynamics of glaciers and the geological processes that shape our planet.
