Why is centrifugal force important in river erosion?
Centrifugal force plays a role in river erosion by helping to move sediment downstream as the river curves or meanders. As the water flows around a bend, centrifugal force pushes the sediment towards the outer bank, leading to erosion on the outer bank and deposition on the inner bank. This process can contribute to shaping the river channel over time.
