Question

21. Which of the following is not related to floods?

• A. Damage to life and property
• B. Erosion of soil
• C. Loss of aquatic life
• D. Falling off the water table

Answer 1

The correct option is D

Falling off the water table

Floods is the result of heavy rainfall and a rise in the level of water bodies in any area.

Explanation of correct option:

(D) Falling off the water table:

• A level below the surface of the soil where there is only water is called the water table.
• Due to the flood in an area, the water table increases because the water is being absorbed by the soil.
• So, falling off the water table is not related to flood.

Explanation of incorrect option:

(A) Damage to life and property:

• Flood causes extensive damage to properties and life.

(B) Erosion of soil:

• Floods cause extensive damage to crop fields, and forests due to this soil erosion occur.

(C) Loss of aquatic life:

• The animals living in water i.e.,.aquatic animals are carried away by the fast flowing flood waters.
• These water animals often get trapped on land areas and when flood water recedes, they die.
• So, floods are the cause of the loss of aquatic life.

Hence, option (D) is correct.
