Question

Which of the following soil can retain water?

• A. Gravel
• B. Sand
• C. Loam
• D. Clay

Hint:

High water retention is essential for certain agricultural practices, particularly in areas with limited rainfall.

Answer 1

The Correct Option is D

Soil Types and Water Retention:
Different types of soil have varying capacities to retain water due to their particle sizes and structure. Analysis of Soil Types:
Gravel: Has large particles with large spaces, leading to rapid drainage.
Sand: Has relatively larger particles than clay, allowing water to drain quickly.
Loam: A mixture of sand, silt, and clay, it offers a balance of drainage and water retention.
Clay: Has very fine particles that pack tightly together, reducing drainage and resulting in high-water retention.
Therefore, Clay soil has the highest water retention capacity due to its fine particle size and close packing.
