A satellite image of an area in Florida shows a river with slight bends along its length. A second satellite image taken of the same area 10 years later shows the same river with a different course. What is the best explanation for the difference in the shape of the river's course between the two satellite images?
Wind blew waves across the water surface, eroding away the bank on one side of the river until the river's course changed its shape
Regular freezing and thawing of the river split the soil along the river banks, changing the shape of the river
Water eroded the banks of the river and deposited the eroded soil on opposite banks, causing the river to form tighter bends
Acid rain chemically weathered the banks along the river, forcing the river to wind back and forth
