Water Conservation and Management Questions

Multiple choice

Wetlands act as natural

  1. filters.

  2. habitats.

  3. tributaries.

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

Wetlands act as natural filters by trapping sediments and absorbing pollutants from water as it flows through them, improving water quality.

Multiple choice

Wetlands help control flooding by

  1. quickly releasing water.

  2. collecting water behind dams.

  3. providing natural water filtration.

  4. absorbing runoff from heavy rains.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wetlands act as natural sponges that soak up excess water during heavy rainfall. This process slows down water movement and reduces the peak flow of runoff, which helps prevent downstream flooding.

Multiple choice

What percent of Earth's water is fresh water?

  1. 70%

  2. 30%

  3. 3%

  4. 1%
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Approximately 97 percent of Earth's water is salt water found in oceans. Only about 3 percent is fresh water, and much of that is locked in glaciers or ice caps.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Water is becoming scarce due to increase in :

  1. population

  2. industries

  3. agricultural activities

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

Water scarcity is a multifaceted issue driven by population growth, industrial expansion, and intensive agricultural practices, all of which increase the demand for limited freshwater resources.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Which of the following industries may be a reason for water scarcity?

  1. Chemical industry

  2. Pharmaceutical industry

  3. Textile industry

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

All these industries cause water pollution by the water discharged into the rivers. The common industrial pollutants are sulphur, asbestos, poisonous solvents, poly-chlorinated biphenyl, lead, mercury, volatile organic chemicals, etc.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Pollution of water due to agricultural operations can be minimized by using:

  1. pesticides

  2. fertilizers

  3. all of the above

  4. none of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pesticides and fertilizers containing chemicals causes water pollution. Pesticides contaminate water as the pesticides are toxic. Fertilizers contain nitrogen and phosphorous, high amount of which is injurious to the underwater organisms. Therefore, the answer is D.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Rich in lather, mixed with oil, black-brown water that goes down the drains from ________ is dirty. It is called waste water.

  1. sinks

  2. toilets, showers

  3. laundries

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

These type of waste water causes the water pollution. It usually gives negative impact on our environment and not good for aquatic life.

Multiple choice chemistry water too little to waste pollution of water water pollution planet earth

Which of the following activity causes water depletion?

  1. Increasing population

  2. Increasing industries

  3. Agricultural activities

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

Factors responsible for the depletion of water table-

(i) Population- due to the increase in population, the open area decreases in order to fulfill the demands such as the house, shops, roads, pavements, office, etc, thereby cutting trees resulting in deforestation which decreases the open area for the seepage of water into the ground.
(ii) Agriculture- for agricultural process water is needed for irrigation for which ground water is used which in turn decreases the water table.
(iii) Most of the people keep the taps open though water is not in use, this is how wastage of water resources occur.
Many industrial practices cause water pollution, for eg-mining, drilling. Oil spills also cause water pollution. These type of pollution leads to depletion of water.

Which of the following is/are correct statement(s) regarding increasing population as a reason for water scarcity?

  1. Increasing population creates demand for construction of houses, shops, offices, roads and pavements.

  2. This decreases the open areas like parks, and playgrounds.

  3. This in turn decreases the seepage of rainwater into ground.

  4. A pukka floor does not allow water to seep in easily, while in a grass lawn water seeps through in no time.

Multiple choice evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

Rain is the ultimate source of water.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The ultimate source of water is the water bodies which are present on earth which includes large oceans, seas, rivers, etc. Rain is only the way of water returning to their sources which they have lost by evaporation.
  • This rain is not an ultimate source of water .the ultimate source are the water bodies present on earth example large oceans, rivers etc
  • So, the correct answer is 'False'.
Multiple choice evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

Which one of the following is not responsible for water shortage ?

  1. Rapid growth of industries.

  2. Increasing population

  3. Heavy rainfall

  4. Mismanagement of water resources
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Water is one of the most valuable resources on Earth. Rainwater fills reservoirs that supply drinking water, provide a habitat for fish to live, and nourishes the soil with water necessary for vegetation.
  • Hence Heavy rainfall is not responsible for water shortage.
  • So, the correct answer is 'Heavy rainfall'.
Multiple choice evs sources of water the lithosphere and the hydrosphere first aid safety and first aid

Primary source of water is

  1. Rivers

  2. Ground water

  3. Lakes

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

The primary source of water on the surface of the earth is rain. Rain is mainly formed due to the precipitation of vapours accumulated due to evaporation. Some part of the rainwater is available as ground water which can be used in case of adversity.

So, the correct answer is option D.
