Give reasons.

Wind can possibly erode the rocks from all the sides.

Answer :

Erosion can also be caused by the actions of the wind that is blown in the earth’s surface. It can result in the formation of geographical features though erosion, transportation and deposition. Wind can erode the rocks from nearly all the sides and create various types of geographical features.


Wind can easily erode rocks having a very soft base resulting in the formation of mushroom/pedestal rocks. In such situations, the wind erodes the soft layers of the base resulting in its erosion. The bottom layers are eroded resulting in the formation of a structure having a mushroom or pedestal-like structure in the top leaving its base like a stand to support the top. Inselberg is another important feature caused by the erosive action of the winds. These are formed by the action of wind in rocks like igneous rocks that are more resistant to the action of wind. Since these rocks have more resistance against the winds, they stand rising above the surroundings forming abrupt hills and cliffs. The feature yardang is basically formed in rocks having a vertical soft base. In such situations, the wind erodes the vertical soft layers of the base resulting in its erosion. These soft layers get eroded leaving crests and summits.
