Erosion is the process by which sediment and other materials are moved from one place to another. There are four main agents of erosion, wind, water, ice, and waves. Deposition is the geological process in which sediments, soil, and rocks are added to a landform or landmass. Erosion and deposition have taken place throughout Earth’s history and have created a variety of landforms. What landforms have been created by erosion?
