Erosion is the process of wearing down and moving surface materials from one place to another through the agents of wind, waves, and running water. Water erosion in streams and rivers carries sediments that act like sandpaper to scrape away rocks, while wave action on shorelines produces fine sand on beaches and forms caves and cliffs. Wind erosion occurs in dry areas with little vegetation, carrying sand that rubs against and wears away rock surfaces and creates distinctive landforms.

1. Erosion The process of Wearing down surface materials. Moving them from one place to another.

2. The 3 agents of erosion Wind Wave Water (Running water)

4. Action of water Water in streams and rivers carry a lot of sediments. As the water runs over rocks, the sediments act like sandpaper, scraping and wearing away the rocks.

10. Action of waves The constant breaking of waves against the shore erodes the seashore to produce the fine sand found on beaches It also results in landforms such as caves and cliffs

18. Wind erosion occurs in areas with little water and few plants to hold the soil in place. Strong winds can carry large amounts of sand which rub and wear away surfaces of rocks in their path Tends to take place mainly at the base of rocks, resulting in interesting landforms Action of wind

19. Denudation The combined processes of weathering and erosion Prolonged denudation can remove the natural protective layer over the Earth This layer may be top layer of soil or vegetation that holds the soil down
