Give a geographical reason for each of the following:

(i) Laterite soil is useful for construction purpose.

(ii) Soils of the Western Ghats are affected by wind erosion.

(iii) The foothills of the Himalayas are prone to excessive soil erosion.

(i) Laterite soils are used as a building material because they become hard like iron when exposed to air. So, they are used as a building material. Laterite soils are red in color due to the presence of iron oxide. These soils are generally coarse in texture and friable and porous in nature.

(ii) Soils of the Western Ghats are affected by wind erosion because a large chunk of Western zone is arid or semi-arid and wind erosion is a result of extreme form of soil degradation due to aridity.

(iii) The foothills of the Himalayas are prone to excessive soil erosion because the vegetation over there is very less. There are not many plant or tree roots to hold the soil in place, which makes the foothills of the Himalayas prone to excessive soil erosion.
