Water Conservation and Management Questions

Multiple choice biology soil : our life soil properties soil - properties basics of soil pollution

Percolation tank is the storage of water for 

  1. Domestic pupose

  2. Industrial use

  3. Irrigation

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The percolation tanks are constructed on the land which is highly permeable. The water which gets collected in the tank is then percolated in the ground. This system helps to recharge the groundwater system. The water can be used by constructing borewells for domestic purpose. Canals can be constructed which can be used for the purpose of irrigation and cultivation of crops. 

Thus, the correct answer is option D.

Which of the following activity helps in rainwater conservation?

  1. Greater absorption

  2. Greater humus content

  3. Greater mineral content

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

Greater absorption allows soil to soak up rainwater, which helps recharge groundwater levels and prevents surface runoff. This is a key mechanism in rainwater conservation.

  1. Non-degradable, non maintainable

  2. Degradable, maintainable

  3. Renewable

  4. Non-renewable
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Natural Resources or Earth resources are those living and non living components of atmosphere, hydrosphere and lithosphere, which can be drawn for supporting life or have potential of being used by humans for their requirements of food, fodder, shelter, clothing, articles of use and recreation.

Inexhaustible resource is a natural resource, which is found in such abundance, that it is unlikely to diminish or get exhausted. E.g., air, solar energy, wind power, rainfall etc.
Exhaustible resource is a natural resource, which is likely to diminish and get exhausted due to continuous use or exploitation. E.g., minerals, fossil fuels, forests etc. Exhaustible resources are of two types renewable and non-renewable.
Renewable exhaustible resource is a natural resource, which gets replenished, recycled or reproduced. E.g., forests, water, agriculture etc.
Non-Renewable exhaustible resource is a natural resource, which is likely to get exhausted with use. E.g., fossil fuels like petroleum, minerals and metals.

Water is an essential commodity for survival. What can we do to help increase water resources?

  1. Deforestation

  2. Reducing the use of vehicles

  3. The burning of the wastage

  4. Afforestation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Afforestation involves planting trees, which helps in water conservation by reducing runoff, increasing groundwater recharge, and maintaining the water cycle. Deforestation and burning waste are harmful to the environment.

Water is considered to be

  1. Renewable and degradable resource

  2. Non-renewable resource

  3. Non-degradable non-maintainable

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

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. Water is considered as the renewable form of energy. The water reserves can be replenished by the rainfall. The water resource is degradable form of resource. The contaminants and pollutants from the industries can degrade the quality of the water in the water bodies. 

Thus, the correct answer is option A.

It is important to make small check dams across the flooded gullies because they-
(i)   hold water for irrigation.
(ii)  hold water and prevent soil erosion.
(iii)  recharge ground water.

(iv)  hold water permanently.
Select the correct options from the above stated reasons-

  1. (i) and (iv)

  2. (ii) and (iii)

  3. (iii) and (iv)

  4. (ii) and (iv)

Explanation

A check dam is a small, often temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity.

Multiple choice evs - i rules are for everyone damaging the forests deforestation and afforestation protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles pollution of soil degradation of land

Which method is most effective in controlling floods?

  1. Digging deep canals

  2. Reforestation

  3. Deforestation

  4. Constructing dams
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Loss of vegetation (deforestation) results in an increased risk of flooding. With natural forest cover, the flood duration should decrease. Reducing the rate of deforestation should improve the incidents and severity of floods. Reforestation and afforestation are two strategies to increase the vegetation cover, that can improve infiltration and interception rates, and thus regulate flood peaks. Reforestation refers to planting trees in areas, where they have been cut down, while afforestation means planting trees, where they have never existed. Dams and reservoirs are effective in controlling floods by reducing peak flows.

Which  one of the following is not a reason for shortage of usable water?

  1. Over exploitation

  2. Climate change

  3. Deforestation

  4. Decrease in sea level
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Overuse of the water resources will result in the exhaustion of the water supply. The climatic change has resulted in global warming and seasonal variations. There is a decrease in the annual rainfall which was received by a region due to shortening of the seasons. Deforestation has resulted in a decrease in the number of trees which thereby affect the amount of rainfall which was received. There is soil erosion which results in water run off.The decrease in the level of the sea is not a reason for the shortage of usable water. 

Thus, the correct answer is option D.

Ground water will not be depleted due to

  1. Afforestation

  2. Thermal power plants

  3. Loss of forests, decreased rainfall

  4. Cropping of high water demanding crops
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Thermal power plants require large amounts of water for cooling, which can lead to significant depletion of local ground water sources. The other options (afforestation, etc.) generally help maintain or improve water tables.
