question: Mona is a scientist studying erosion at a university. She is observing a river. If she starts taking erosion measurements at the mouth of the river and moves up to the head of the river, what will she find happens as the slope gets steeper?
choices.text: erosion decreases erosion increases
choices.label: A B
para: Water flowing over a steeper slope moves faster and causes more erosion.
