Water in the aquifers can be usually pumped out with the help of:

  1. handpumps

  2. drilling

  3. tubewell

  4. both $A$ and $C$


Correct Option: D
Explanation:

When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out with handpump or tubewell.

If we dig a hole in the ground near a water body we may find that the soil is ________.

  1. oily

  2. moist

  3. red

  4. both $A$ and $B$


Correct Option: B
Explanation:

If we dig a hole in ground near a water body, the soil becomes moist. Because the ground water accumulated inside the ground provide moisture to the soil.

The soil cannot be find oily because oil is found in few regions and found deep inside the earth.
The soil cannot be find red as red soil is formed by crystalline rocks and these rocks are found very rarely. 

Groundwater gets recharged by the process of:

  1. pumping

  2. heavy rainfall

  3. infiltration

  4. None of the above


Correct Option: C
Explanation:

Groundwater gets recharged by this process of infiltration.
Infiltration is the process by which precipitation or the bulk of rainwater and melted snow soaks into subsurface soils and moves into rocks through cracks and pore spaces. so when the water soaks into the ground the groundwater gets recharged.

Tubewell are used to pump out water from :

  1. tanks

  2. ground

  3. river

  4. aquifer


Correct Option: B,D
Explanation:

Tubewell are used to pump out water from ground and acquifer.
