Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. wind erosion
A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed in deserts by the action of wind erosion.The wind carried sand close to the ground, carving the bottom of these rocks more than the top.
- When the erosive power increases from the ground level, the rocks that are resistant take the shape of mushroom with a large top and a small neck.
- They are formed by various processes of weathering and erosion. They are also formed due to glacial action or any other disturbance.
