Erosion and Deposition by Gravity
Erosion and deposition by gravity are fundamental geological processes that shape the Earth's surface over time. Driven by the force of gravity, these processes involve the movement of rock, soil, and sediment down slopes, influencing the formation of landscapes and landforms. Erosion refers to the wearing away of materials, while deposition involves the settling of eroded particles in new locations. From the gradual carving of valleys to the creation of sedimentary layers, the dynamic interplay of erosion and deposition by gravity plays a crucial role in sculpting the diverse features we observe in the Earth's terrain.
