Water Conservation and Management Questions

Multiple choice

Which of the following is the odd one out?

  1. Aquifer

  2. Water table

  3. Ground water

  4. Sleet

  5. Well
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sleet is just rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. However, it can accumulate like snow and cause a hazard.

Multiple choice

  1. Some rain water collects in spaces and cracks in the rocks and soil underground. This is called groundwater.

  2. Another name of water cycle is cloud cycle.

  3. Clouds are formed after evaporation takes place.

  4. Some rain water runs off to rivers, lakes and ponds.

  5. Rain water can be collected and stored for our use.

B Correct answer
Explanation

This is a wrong statement. Another name of water cycle is hydrologic cycle.

Multiple choice

In areas with inadequate water reservoir release or canal flow, the ________ system is more rational.

  1. well

  2. river lifting

  3. tank

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

If adequate reservoirs are available, then canal system is used, in which the main canal, which receives water from one or more reservoirs or from rivers, is divided into branch canals having further distributaries to irrigate fields. However, in areas where canal flow is insufficient or irregular due to inadequate reservoir; the lift system is used. Water is directly drawn from the rivers. Tanks and wells cannot be the answer as they store run-off water or water through seepage.

Multiple choice

Recharging of ground water by allowing the rain water to penetrate the soil is called as

  1. water level

  2. percolation

  3. drip irrigation

  4. water irrigation

  5. conservation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In this method, the water flowing on the houses, roads, ground or lawns etc, is collected in ponds and storage tanks. This water is allowed to penetrate (percolate) into the ground to recharge the ground water. This is also known as water harvesting.

Multiple choice

Match the following.

1. Rain water A. Secondary source of water
2. Ground water B. Water conservation
3. Boiling C. Primary source of water
4. Saving water D. Kills germs

  1. 1 - A, 2 - C, 3 - B, 4 - D

  2. 1 - C, 2 - A, 3 - B, 4 - D

  3. 1 - C, 2 - A, 3 - D, 4 - B

  4. 1 - B, 2 - A, 3 - C, 4 - D

  5. 1 - C, 2 - B, 3 - A, 4 - D
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct answer.  Rain water is the primary source of water. Ground water and surface water is the secondary source of water. Boiling is the process that can be use to kill the germs present in the water and saving and using water carefully is called water conservation.

Multiple choice

Which of the following is not a water body?

  1. Lakes and rivers

  2. Oceans

  3. Aquifers

  4. Ground water

  5. Trees

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

'Water body' means water source, i.e. a reserve of water. Trees are not water bodies but they are a part of water cycle. 

Multiple choice

  1. By not overusing the pesticides and fertilisers in agriculture.

  2. By not throwing oil, waste materials, paints, plastics, etc. into drainage.

  3. By using bicycles and public transport as modes of transportation.

  4. By planting new trees.

  5. All of the above

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

Water can be conserved by following the given measures of water pollution.

Multiple choice

What is the major use of, in- stream water?

  1. Producing hydrolectric power.

  2. Disposal of industrial wastes.

  3. Agricultural irrigation.

  4. Domestic use.

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

A major in- stream use of water is for producing hydrolectric power, in which turbines are turned by the moving water to generate electricity. 

Multiple choice

Which of the following is considered as the best method of rainwater harvesting?

  1. To have an underground harvesting tank

  2. To have a roof top harvesting tank

  3. To use the bamboo drip irrigation system

  4. To have an open pit harvesting tank
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The underground rainwater harvesting tanks are the best because they capture water from various places for storage. The water from the roof as well as landscaped areas can be canalised into these tanks.  

Multiple choice

  1. Only (a)

  2. Only (b)

  3. Both (a) and (b)

  4. All of these
