43. You notice a stream where the load mostly consists of large rocks and boulders that crash into each other as they are carried downstream by turbulent waters. What effect do you think these characteristics have on erosion?

Answer 1

A: the bed load probably causes very little erosion because the rocks don’t move very much
B: the steep gradient probably causes heavy erosion because gravity makes the water cut deep into the channel
C: the bed load probably causes heavy erosion as the large rocks scrape away the sides and bottom of the channel
D: both B and C
