Question

Seema took some gravel in a perforated coconut shell. When she poured water into a perforated coconut shell filled with gravel, water drops come out through the hole of the coconut shell quickly. What inference can be arrived at from this?

• A. Gravels have high organic content.
• B. Gravels have low water absorption capacity.
• C. Gravels have high water absorption capacity.
• D. Gravels are suitable for agriculture.

Answer 1

The correct option is B Gravels have low water absorption capacity.

A good soil has high organic content and high water absorption capacity. Seema's observation shows that gravels are not absorbing water at all i.e. they have the least water absorption capacity. This happens because gravels are bigger in size and are not packed tightly with each other allowing water to escape through them. Also, gravels has less organic content. Due to these reasons gravels are not good for agriculture.
