How is earth's surface likely to change along the edges of a bend in a river channel? erosion takes place along the inner edge as water flows relatively slowly. erosion takes place along the outer edge as water flows relatively fast. deposition takes place along the inner edge as water flows relatively fast. deposition takes place along the outer edge as water flows relatively slowly.

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

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

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
