Question

the steeper a streams gradient, the:
erosion stays the same no matter the gradient
less erosion that happens
the more erosion that happens

Explanation:

To determine the answer, we analyze the relationship between a stream’s gradient (steepness) and erosion. A steeper gradient means the stream flows faster, which increases its ability to erode. So, a steeper gradient leads to more erosion. The first option claims erosion stays the same, which is incorrect. The second option says less erosion occurs with a steeper gradient, which contradicts the relationship (faster flow = more erosion). The third option, "the more erosion that happens", aligns with the principle that steeper gradients (faster stream flow) cause more erosion.

Answer:

the more erosion that happens
