The Power of Weathering and Erosion

The video tutorial explains how natural processes like weathering and erosion shape Earth's surface. Weathering involves the breakdown of rocks and materials, primarily through the action of water. Erosion, often carried out by moving water, transports these materials to new locations. Glaciers, large moving sheets of snow and ice, also play a significant role in erosion, carving out valleys and transporting debris.
