Question

12. Assertion (A): Laterite soils are generally poor in phosphoric contents and develop deep cracks during hot weather, Reason(R): This soil develops in areas of with high temperature and heavy rainfall. * a. Both A and Rare true and Ris the correct explanation of A, b. Both A and Rare true but is not the correct explanation of A c. A is true but Ris false, d. A is false but R is true​

Answer 1

Both a and r are true and the r is the correct explanation of a

Answer 2

The correct option is A is false but R is true​.

• Clay is abundant in black soil. It has a high water retention capacity since it is deep and resistant.
• When wet, they expand and become sticky, and when dry, they form deep broad fissures. This aids in self-aeration, which leads to nitrogen absorption from the atmosphere.
• Laterite soils which are of red/brown colour are formed in extreme temperature and heavy rainfall environments. Thus, the reasoning sentence about the soil is correct.
