Erosion features are landforms created by the gradual wearing away of soil and rock due to natural forces like water, wind, and ice. Common examples include valleys, canyons, and cliffs, which develop over long periods as these forces remove material from the Earth's surface. These features can also include gullies and rills, which are small channels formed by the flow of water during rainfall. Erosion can significantly shape landscapes, affecting ecosystems and human activities by altering land use and natural habitats. Understanding erosion helps in managing and preserving the environment.
