Question

How is Earth's surface likely to change along the edges of a bend in a river channel?

Answer 1

i think that the answer is Deposition takes place along the inner edge as water flows relatively fast. hope this helps

Answer 2

A river flowing down a straight path will be moving the fastest in the middle of the river, just below the surface.  But if that river approaches a bend, the speed changes.  

SINCE FAST MOVING WATER DOES MORE EROSION, THE FAST OUTSIDE BEND IS WHERE EROSION OCCURS ON A RIVER

THE SLOWER INSIDE PART OF THE BEND IS WHERE DEPOSITION OCCURS ON A RIVER.

OUTSIDE BEND = FAST = EROSION

INSIDE BEND = SLOW = DEPOSITION
