Q. Consider the following statements about the types of soils found in India:
Which of the above given statements is/are correct?
The correct option is C 3 only
Explanation:
Statement 1 is incorrect: Red soil develops a reddish colour due to wide diffusion of iron in crystalline and metamorphic rocks. Crystalline and metamorphic rocks such as acid granites, gneisses, and quartzites are the primary parent rocks for Red Soil.
Statement 2 is incorrect: Laterite soils (not red soil) are widely cut as bricks for use in house construction. ‘Laterite’ means brick in Latin. They harden greatly on losing moisture.
Statement 3 is correct: Fertile alluvial soils are saline in areas of intensive agriculture with excessive irrigation, as excessive irrigation with dry climatic conditions encourages capillary action resulting in salt accumulation on the top layer of the soil.
