Which feature forms in the upper course of a mountain river due to strong vertical erosion?
Answer and explanation
Correct answer: V-shaped valley
The governing concept is vertical, or downward, river erosion in the youthful upper course. Because the river has a steep gradient and strong energy, it cuts mainly into its bed, producing a narrow valley with steep sides and a V-shaped cross-section. Therefore, option C is correct. A delta and floodplain are depositional features of lower or gentler reaches, while a lagoon is a coastal water body.
