Q 3. State two differences between Alluvial soil and Black soil. ?

Explanation:

Alluvial SoilBlack Soil
1. Originated from the transported alluvium brought by the rivers.Originated from the solidification of basic lava, spread over large areas of Deccan Plateau during volcanic activity.
2. Rich in potash and humus but deficient in phosphorus and nitrogen.Rich in lime, alumina, iron, potash, magnesium carbonate and calcium and deficient in potash, nitrogen and humus.
Q 4. What is soil erosion? Mention two steps that could be taken to prevent soil erosion.

Explanation:
Removal or destruction of top soil by the agents like winds and running water is called soil erosion.
1. Afforestation : The best way to prevent soil erosion is to increase area under forests.
2. Constructing dams and barrages : Soil erosion by flood can be checked by constructing dams or barrages over the rivers. This checks the speed of water thereby saving soil from erosion.

Q 5. Mention some of the properties of Red Soil.

Explanation:

(i) Red Soil is formed in situ by weathering of the ancient crystalline and metamorphic rocks.
(ii) It is rich in iron content, hence, it is red in colour.
(iii) Its productivity increases with regular use of fertilisers.
(iv) It is porous in nature but not retentive to moisture.
(v) It is suitable for dry farming as it does not require much moisture.
