Natural raised banks along a river are formed by which process?

Correct answer: River deposition

Direct answer: D, river deposition. During a flood, water rises and spreads over the river banks. As it leaves the channel, its speed and carrying power decrease suddenly. The heavier particles, such as sand and coarse silt, settle first near the channel. Repeated floods build raised embankments beside both banks; these are natural levees. A is erosion by moving ice, B is the wearing of surfaces by wind-blown particles, and C is erosion caused by waves along a coast. None of these processes explains raised river banks. Memory cue: floodwater slows outside the channel, so sediment drops beside the river and builds a natural levee.
