Question

Wells are fed by:

• A. Pond water
• B. Lake water
• C. Rain water
• D. Groundwater

Answer 1

The correct option is D

Groundwater

The correct option is : D

Explanation of the correct option:

1. The rainwater fills up the lakes and ponds.
2. Some water gets absorbed by the soil and ground.
3. The water that is not absorbed by soil and ground penetrates the ground which adds to the groundwater level.
4. This groundwater becomes the source of water for wells. So, wells are fed by groundwater.
5. The groundwater is more convenient and less exposed to pollution.

Explanation of the incorrect options:

Option A: Pond water is a source of surface water and hence does not fill wells.

Option B: Lake water is also a source of surface water and hence does not fill wells.

Option C: While a portion of rainwater seeps underground, percolating through porous rocks and adding to groundwater, it is not a direct and major source of wells.

Final answer : Thus, wells are fed by groundwater.
