Choose the characteristic that is true about Laterite soil:
Show Hint
- It is a clayey soil.
- It is moisture retentive.
- It is rich in calcium.
- It undergoes desiccation.
The Correct Option is D
Solution and Explanation
Laterite soil is rich in iron and aluminum and undergoes desiccation (drying out) under high temperature and low rainfall conditions.
Step 2: Analysis of other options.
- (A) Incorrect: Laterite soil is not clayey but rather coarse in texture.
- (B) Incorrect: Laterite soil is not moisture-retentive; it is usually dry due to its nature.
- (C) Incorrect: Laterite soil is not particularly rich in calcium, but it contains iron and aluminum.
Step 3: Conclusion.
The correct answer is (D), as Laterite soil undergoes desiccation in dry conditions, leading to its hardened structure.
Final Answer: It undergoes desiccation.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
