Glacial activity refers to the processes and features associated with the movement and melting of glaciers. Glaciers are large masses of ice that slowly flow over land due to the weight of the ice and the force of gravity. This movement, along with the melting of ice, results in a range of geological and hydrological effects on the landscape.
Answer: Glaciers form from the compaction and recrystallization of snow into ice over many years.
Answer: Glaciers can erode the land through processes such as plucking and abrasion.
Answer: Glacial activity can create landforms such as moraines, drumlins, cirques, aretes, and U-shaped valleys.
Answer: The melting of glaciers contributes to the formation of streams, lakes, and other water bodies.
