External Forces Affecting Earth • EARTH IS ALSO AFFECTED AND SHAPED BY EXTERNAL FORCES, THEY ARE WEATHERING, EROSION, AND DEPOSITION Weathering The breakdown of Earth’s crust into smaller pieces Smallest particles are called sediment Erosion The process by which weathered rock, sand, and soil are carried away and moved to a new location Agents 3 main natural agents aid the process of weathering and erosion. They are: Water Ocean waves, rivers, streams, and runoff Ice Frost wedging, glacier formation & movement Wind Transports rock material against gravity Deposition The depositing of particles and sediment in a new location, resulting in the creation or growth of a landmass Weathering Erosion Deposition
