Explain the relationship between the steepness of a river and the rate of erosion.(1 point)

Water always flows at the same speed. This means erosion always occurs at a constant rate.

Water flows faster down a steeper grade. This causes erosion to occur more slowly.

Water flows faster down a gentle grade. This causes erosion to occur more quickly.

The correct response is:

Water flows faster down a steeper grade. This causes erosion to occur more quickly.

In a river with a steep slope, the increased gravitational pull results in faster water flow. The higher velocity of the water enhances its ability to carry away sediment and erode the riverbed and banks, leading to a greater rate of erosion compared to gentler slopes where water flows more slowly.
