Water Conservation and Management Questions

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

Greatest problem in the water conservation is to reduce the amount of

  1. Ground water

  2. Precipitation

  3. Evaporation

  4. Run off water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation from water reservoirs in hot arid climates causes a loss of 10 vertical feet a year. This water loss can be controlled by construction of reservoirs with greater water depth and concentration of water into single reservoir. Also wind blowing across the surface of water reservoir causes additional evaporation. A windbreak helps to conserve water. Thus the correct answer is option C.

Multiple choice geography structure of ocean floor relief of the ocean ocean water movement ocean circulation

The percentage of freshwater available on the surface of land is ______.

  1. 3

  2. 5

  3. 2

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

The percentage of freshwater available on the surface of land is $3$.
Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 3 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields.

Rainwater harvesting is collecting & storing rainwater, which includes activities aimed at:

  1. harvesting surface water

  2. groundwater

  3. prevention of losses through evaporation and seepage

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

In general, water harvesting is the activity of direct collection of rainwater. The rainwater collected can be stored for direct use or can be recharged into the ground water. Rain is the first form of water that we know in the hydrological cycle, hence is a primary source of water for us.It is also the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff).

Which one of the following is a sign of water scarcity?

  1. Dried fields having cracks on them

  2. Nutrient deficient plants

  3. Struggle to obtain water from bore wells

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Water scarcity is the lack of fresh water resources to meet water demand. It is mainly due to lack of water or due to a lack of adequate machinery or tools to supply water.
  • The effects of water scarcity can be grouped into these 4 broad categories. They are Health, Hunger, Education, and Poverty.
  • The sign of water scarcity includes the following. They are Dried fields having cracks on them, Nutrient deficient plants and Struggle to obtain water from bore wells.
  • So, the correct answer is 'All of the above'.

Water harvesting is done by ____________ processes.

  1. rainwater

  2. groundwater

  3. both A and B

  4. atmospheric water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Water Harvesting
It means storing rain where it falls or storing the run off in your own village or town. And taking measures to keep that water clean by not allowing polluting activities to take place in our locality.
It can be done by two major processes:
1. Rainwater harvesting
It is a method of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers.
2. Groundwater harvesting 
Groundwater harvesting is a method to save water placed under the ground to control the groundwater flow in an aquifer, and to raise water table.

Find out the wrong statement from the following:

  1. Water evaporates from plants, animals and oceans

  2. Animals living in the water are not harmed during floods

  3. There is no vegetation during draughts

  4. Water available for use is very limited
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water evaporates from plants through transpiration and oceans through evaporation. There is no vegetation during draughts as there is no availability or very little presence of water in the ground making the area dry and cracks the ground.

Water available for use is very limited as most of the water present in the earth's surface is saline.

Rain water harvesting is a method employed to:

  1. stop soil erosion in a place

  2. raise the water table of a place

  3. increase afforestation around a place

  4. decrease floods and droughts in a place
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rain water harvesting is a method employed to raise the water table of the plane. Its is a single method by which rainfall is collected for future usage. The collected rainwater may be stored, utilized in different ways or directly used for recharge purposes. It is the accumulation and storage of rainwater for re-use on site, rather than allowing it to run-off.

  2. on channel storage of water

  3. creation of new water bodies

  4. roof-top rainwater harvesting
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Harvesting rain water from roof tops is an easy and eco- friendly method of augmenting house hold level water availability. Roof top rain water harvesting involves diverting and recharging or storing part of rain water that falls on the roof of a house.

  4. sea
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To prevent excess use of water from taps and tanks, we can collect water from rain.
