| Consider the following statements: |
| 1. Red soils are reddish in colour due to wide diffusion of iron in crystalline and metamorphic rocks. |
| 2. Laterite soils are not much useful for agriculture but provide good building material. |
A) Only 1 is correct
B) Only 2 is correct
C) Both 1 and 2 are correct
D) Neither 1 nor 2 is correct
Correct Answer: C
Solution :
[c] Laterite is a soil and rock type rich in iron and aluminium, and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. Laterite has commonly been referred to as a soil type as well as being a rock type. Laterite soils have a high clay content, which mean they have higher Cation Exchange Capacity and water-holding capacity than sandy soils. However, if lateritic soils become degraded, a hard crust can form on the surface, which hinders water infiltration and the emergence of seedlings.
