In the upper course of a river, erosion is mostly in which direction?
Answer and explanation
Correct answer: Downward
The governing concept is vertical erosion in a river’s youthful or upper course. The upper course usually has a steep gradient, so gravity gives the river considerable energy to cut downward into its bed, producing V-shaped valleys, gorges, and waterfalls. Therefore, option A is correct. Lateral erosion becomes relatively more important downstream, while the other choices do not describe normal river action.
