Correct option is A
The correct answer is (a) River
Explanation:
A V-shaped valley is typically formed by the erosional activity of a river. As the river flows through land, it erodes the rock and soil, carving out a valley with steep sides that often form a V-shape.
A V-shaped valley is typically formed by the erosional activity of a river. As the river flows through land, it erodes the rock and soil, carving out a valley with steep sides that often form a V-shape.
This process is known as downcutting or vertical erosion, and it creates valleys where the riverbed is significantly lower than the surrounding land. The V-shape is characteristic of young rivers or rivers flowing through mountainous terrains.
Information Booster:
- The process of erosion by flowing water gradually deepens and widens the river channel, leading to the V-shape.
- Erosion in the upper course of rivers is more pronounced and leads to the formation of such valleys.
- Over time, as rivers age and move to flatter areas, they may create U-shaped valleys due to the combination of erosion and deposition.
- V-shaped valleys are usually found in regions with steep slopes, where the river has not yet reached its mature stage.
- Rivers in their youthful stages, especially in mountainous areas, are responsible for carving out these valleys.
Additional Information:
- Ocean current (b) – Ocean currents can shape coastlines.
- Wind (c) – Wind can cause erosion and shape sand dunes or desert landscapes.
- Snow or ice (d) – While glaciers, formed by ice, can create U-shaped valleys.
