Glacial Erosion

Glacial erosion is the process by which glaciers carve and reshape the land through the movement of ice and the materials it carries. Glaciers have a significant impact on the shaping of the Earth's surface, and their erosional power can create striking landforms.

Key Concepts

• Glacial Movement: Glaciers move due to the force of gravity and can pick up and transport large amounts of rock and sediment.
• Erosion: Glacial erosion occurs through processes such as plucking and abrasion, where ice and debris scrape and carve the landscape.
• Landforms: Glacial erosion can create distinctive landforms such as valleys, cirques, and aretes.
• Effects on the Environment: Glacial erosion can significantly alter the topography and hydrology of an area, impacting ecosystems and human activities.
