Multiple choice social science water: a precious resource water table groundwater and depletion of water table the water cycle

Which of the following does not cause a depletion in the water table of a place?

  1. Constructing factories and houses

  2. Making concrete roads and floors

  3. Deforestation

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All the three options cause depletion in water table in a place as first and second case consume water and third case decrease water retention of soil and also decrease rainfall.

So, none of these is the correct option.                     

Multiple choice social science water: a precious resource water table groundwater and depletion of water table the water cycle

What happens to the water table of a place having droughts for a long period of time?

  1. It gets higher because of continuous evaporation and flow.

  2. It gets lower because of continuous evaporation and flow

  3. It gets replenished continuously

  4. can't say anything
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The water table is also called as groundwater table. It's recharge depend on the recharge from infiltration of precipitation so when a drought hit the land surface it affects the water level below ground. This result in falling groundwater level due to evaporation and flow.

So, the correct option is 'it gets lower due to continuous evaporation and flow'.

Multiple choice social science water: a natural resource water table groundwater and depletion of water table the water cycle

At places, the groundwater is stored between layers of hard rock below the water table. This is known as __________.

  1. a reservoir

  2. an aquifer

  3. a hard water

  4. a well water
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand or salt). Ground water can be extracted using a water well.

Multiple choice social science water: a natural resource water table groundwater and depletion of water table the water cycle

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

  1. handpumps

  2. drilling

  3. tubewell
  4. both $A$ and $C$
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Multiple choice social science water: a natural resource water table groundwater and depletion of water table the water cycle

Groundwater gets recharged by the process of:

  1. pumping

  2. heavy rainfall

  3. infiltration

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

Multiple choice

What is a way we can help Earth by conserving water?

  1. Turn off the water while brushing our teeth.

  2. Properly throwing away our trash.

  3. Water our lawn sparingly.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Conserving water involves multiple habits, such as turning off the tap while brushing teeth, managing waste to prevent pollution, and watering lawns efficiently.

Multiple choice

The area of land that is drained by a river is known as a

  1. Surface Water

  2. None of these

  3. Watershed

  4. River System
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A watershed is the specific geographic area where all rainfall and runoff drains into a common body of water, such as a river or lake. Surface water refers to water on the ground, while a river system includes the river and its tributaries.
