The natural process that moves weathered rocks and soil from one place to another is called "erosion." Erosion occurs through various agents, including water, wind, ice, and gravity, which can wear away and transport materials from their original location. For example, flowing water can carry sediment downstream, while wind can erode and shift sand in desert environments. This process is essential in shaping landscapes and contributes to the formation of features such as valleys, deltas, and canyons. Erosion can also lead to soil loss, impacting agricultural land and ecosystems.
