Why do meandering rivers meander (move)across their floodplain?
A)because the large amounts of sediments that choke the rivers create point bars that are easily eroded away by additional flow of the rivers
B)because they carry very small amounts of sediment and thus are not slowed down as a result of friction between the sediment and the river bottom
C)because they are curved,which causes erosion on one side of the curve and deposition on the other side of the curve,thus moving the river in the direction of erosion
D)because sediment is constantly being deposited on the river bottom,which causes the river to overflow its banks and create a new channel

Question

Quizplus · Accepted Answer

Meandering rivers are curved, and the water flows faster on the outside of the bend, causing erosion. On the inside of the bend, the water moves slower and deposits sediment. This deposition causes the meander to migrate downstream in the direction of the erosion, resulting in the river channel moving back and forth across its floodplain.
