Which of the following increase the rate of percolation of rain water into the soil?

  1. Constructing check dams

  2. Vegetation and trees

  3. Overgrazing

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

Check dams are specifically designed to slow down the flow of runoff, which increases the time water spends on the soil surface, thereby significantly increasing the rate of percolation into the groundwater.

Rain water harvesting is a method employed to:

  1. stop soil erosion

  2. raise the water table

  3. increase afforestation

  4. decrease floods and droughts

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. All the water was collected into a well and helps in raising water table.

  1. Water cycle has stopped functioning.

  2. The total amount of water on earth has decreased.

  3. The amount of potable water is decreasing because of over usage.

  4. Due to increasing frequency of floods and droughts.

C Correct answer
Explanation

The amount of potable water is decreasing because of over usage. Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.

Which of the following does not show water shortage?

  1. Taps running dry

  2. Long queues for getting water

  3. Marches and protests for demand of water

  4. A family gets three buckets of water per person per day

D Correct answer
Explanation

Water shortage is the lack of sufficient available water resources to meet the demands of water usage within a region.
There seems no water shortage as three buckets of water per person is enough for satisfying their daily needs.

  3. More and more water is being used for producing food and by the industries.

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

All of the following factors are leading to shortage of water.

(1) The demand for water is increasing day-by-day.
(2) The number of people using water is increasing with rising population.  In many cities, long queues for collection of water are a common site.
(3) More and more water is being used for producing food and by the  industries.

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

The process of seeping out water into the ground is called:

  1. evaporation

  2. infiltration

  3. transpiration

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

The process of seeping out water into the ground is known as infiltration.

 It is process by which water goes into the ground resulting in increase in water table.
The process is not evaporation as it means evaporating the water present on the ground. 
The process is not transpiration as it is the process by which moisture is carried through plants from roots to small pores on the underside of leaves.

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.
