Detailed explanation-1: -External forces, such as weathering and erosion, also alter landscapes and in some instances create the soil that is needed for plant life. Weathering refers to physical and chemical processes that change the characteristics of rock on or near the earth’s surface.
Detailed explanation-2: -Wind, water, and ice are the three agents of erosion, or the carrying away of rock, sediment, and soil. Erosion is distinguished from weathering-the physical or chemical breakdown of the minerals in rock. However, weathering and erosion can happen simultaneously.
