What is a common natural cause of erosion?

Gravity is a fundamental force that plays a significant role in the process of erosion. It pulls water, soil, and rock materials downward, facilitating the movement and transport of these materials from higher elevations to lower areas. This natural process occurs over time as gravity acts on slopes, riverbanks, and cliffs, leading to the gradual wearing away of land surfaces. Understanding gravity's role in erosion is crucial for developing effective erosion and sediment control practices, as it helps identify areas most at risk of erosion and guides the implementation of preventive measures in land use and management.
