Which statement best describes how river meanders form?
A)Erosion of the river bank on the inside of bends in the river is accompanied by deposition on the outside of bends, causing meander loops to grow through time.
B)Erosion of the river bank on the outside of bends in the river is accompanied by deposition on the inside of bends, causing meander loops to grow through time.
C)Deposition of sand on both the inside and the outside of bends in the river forces the channel to become more sinuous over time.
D)Erosion of sand from both the inside and the outside of bends in the river forces the channel to become more sinuous over time.
E)Floods cause the river to take an increasingly sinuous course, forming meander loops.

C)meander loops fill with sand and the river is forced to straighten out its channel
