Geography

Mass movements, erosion, and deposition

In Class 11 Geography, this topic within “Geomorphic Processes” explains how weathering, gravity, running water, wind, glaciers, waves, and underground water reshape the land. Students learn to distinguish mass movements such as landslides and soil creep from erosion, examine how sediments are transported, and understand deposition that builds features such as fans, floodplains, dunes, moraines, and deltas. It connects processes, landforms, and environmental impacts through clear geographical examples.
