उत्तर
Wind can possibly erode the rocks from all sides, because.
- when a rock’s bottom is soft, the constant wearing down action of the wind, the bottom gets eroded away to form a mushroom like structure.
- Certain hard rocks like igneous rocks are more resistant to wind action. Isolated residual hills are formed from their surroundings.
- When winds blow over the hard and soft layers of rocks the soft layers get eroded leaving irregular crests.
