This model helped us compare two rivers to show how ______.

• Rivers which are slower erode more rock.

• Rivers which flow for a longer time erode more rock.

• Rivers which flow for a shorter time erode more rock.

• Rivers which flow together erode more rock.

Is this student's model correct?

• Yes, because slow rivers would erode more rock

• No, because rivers don't erode rock

• Yes, because the rivers eroded the same amount of rock

• No, because fast rivers would erode more rock
