Questions Related to water: a natural resource

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

chemistry water: a natural resource water resources and conservation receding water table water conservation and irrigation

  1. Constructing check dams

  2. Vegetation and trees

  3. Overgrazing

  4. All of the above

Show answer
Correct Option: A

Rain water harvesting is a method employed to:

chemistry water: a natural resource water resources and conservation receding water table water conservation and irrigation

  1. stop soil erosion

  2. raise the water table 

  3. increase afforestation 

  4. decrease floods and droughts 

Show answer
Correct Option: B
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.

"Catch it where it falls" is the basic idea behind :

chemistry water: a natural resource water resources and conservation receding water table water conservation and irrigation

  1. making dams to store water

  2. recycling of water

  3. rain water harvesting

  4. condensation of water vapour

Show answer
Correct Option: C
Explanation:

'Catch it where it falls'  is the basic idea behind the rain water harvesting. Rain water harvesting is the accumulation and storage of rain water for reuse on site rather than allowing it to run off.

Why is water scarcity increasing day by day?

chemistry water: a natural resource where do we get water from? why conserve water uses of water

  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.

Show answer
Correct Option: C
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?

chemistry water: a natural resource where do we get water from? why conserve water uses of water

  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

Show answer
Correct Option: D
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.

The amount of water on earth today compared with the amount of water on earth at the time it was formed about 5 billion years ago is :

chemistry water: a natural resource where do we get water from? why conserve water uses of water

  1. The same amount

  2. About 80 per cent of the original amount

  3. About 50 per cent of what is was originally

  4. Cant say

Show answer
Correct Option: C
Explanation:

The amount of water on earth today compared with the amount of water on earth at the time it was formed about $5$ billion years ago is about $50$ per cent of what it was originally.

Which of the following factor/(s) are leading to shortage of water?

chemistry water: a natural resource where do we get water from? why conserve water uses of water

  1. The demand for water is increasing day-by-day.

  2. The number of people using water is increasing with rising population.

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

  4. All of the above.

Show answer
Correct Option: D
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.

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

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

  1. evaporation

  2. infiltration

  3. transpiration

  4. None of these

Show answer
Correct Option: B
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.

Groundwater accumulates between the layer of hard rocks. It is known as:

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

  1. pond

  2. water table

  3. surface water

  4. aquifer

Show answer
Correct Option: D
Explanation:

Ground water accumulator between the layer of hard rocks (water bearing permeable rock, rock fractures). It is known as aquifer.

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

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

  1. a reservoir

  2. an aquifer

  3. a hard water

  4. a well water

Show answer
Correct Option: B
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.
