Defining Erosion: The Wearing Away of Earth 's Surface

Erosion is thee geological process by which soil, rock, and tell surface materials are gradually worn way from their original location and transported else where. It differs from from weathering, which only breaks down rock in place with out moving thee particles. Erosion involves both the detachment and movement of sediments by natural agents such as water, wind, ice, and gratis process plays a cical role rzeźbirtting landsapes bey wearn gouring moungs, carv valleys, respints, espingens.
