  1. get lower

  2. get higher

  3. remain unaffected

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The level of water table falls in a place, where the number of water pumps increases because with the help of water pumps groundwater is extracted and this depleted groundwater is not replaced as concrete houses and roads do not allow the rainwater to seep through the soil.

In a small town, the number of water pumps, concrete houses and roads increased. The water table of that place will:

  1. get lower

  2. get higher

  3. remain unaffected

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Due to number of water pumps the water level decreases due excess use of water, and if the number of roads and houses increases the rainwater absorption decreases so that ground water cannot refill after the excess use.
