Question

Which soil is formed due to leaching by heavy rainfall?

• A. Red and yellow soil
• B. Black soil
• C. Laterite soil
• D. Desert soil

Hint:

Laterite soil → Heavy rainfall + leaching → Low fertility. Common in Kerala, Karnataka, and hilly regions of India.

Answer 1

The Correct Option is C

Step 1: Understanding leaching process
Leaching is the process in which heavy rainfall washes away soluble nutrients and minerals from the soil, leaving behind less fertile soil.

Step 2: Identify soil type
- Laterite soil is formed under conditions of high temperature and heavy rainfall.
- Due to intense leaching, laterite soils are poor in nutrients like nitrogen, phosphorus, and potassium.
- They are rich in iron and aluminium, which gives them a reddish color.

Step 3: Conclusion
Hence, the soil formed due to leaching by heavy rainfall is Laterite soil.
The correct answer is option (C).
