Why do we celebrate water day every year?

  1. We celebrate water day every year to attract the attention of everybody towards the importance of conserving water.

  2. It is a tradition.

  3. It is for commercial purposes.

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
World water day is celebrated every year on 22nd March. Water is essential for life on earth. The water available for consumption on earth is limited. Only 3% of the water on earth is freshwater. All lakes, rivers and swamps combined include a very small part that is 0.3% of the earth's total freshwater reserves. Hence water should be used judiciously. So water day is celebrated every year to attract the attention of everybody towards the importance of conserving water.
Thus, the correct answer is option A.

Greatest problem in water conservation is to reduce the amount of

  1. Ground water

  2. Precipitation

  3. Run-off water

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

Greatest problem in water conservation is to reduce the amount of evaporation. Evaporation is a process by which a large amount of water evaporate in the form of water vapours (gaseous form)

So, the correct answer is 'Evaporation'

Which of the following can be used to conserve water in homes?

  1. Composting toilets

  2. Rainwater harvesting

  3. Automatic faucet

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

Water-saving technology for the home includes:

  • Low-flush toilets and composting toilets. These have a dramatic impact in the developed world, as conventional western toilets use large volumes of water. 
  • Rainwater harvesting high-efficiency clothes washers weather-based irrigation controllers garden hose nozzles that shut off water when it is not being used, instead of letting a hose run. Low flow taps in wash basins. 
  • Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.

How do you conserve water by watering plants?

  1. By watering optimum quantities regularly

  2. By watering heavily but less often

  3. By watering Twice a week

  4. By watering very little
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water heavily may  result in root rot due to water logging preventing the roots from respiring aerobically. When roots respire anerobically alcohol produced as a byproduct results in root rot. Watering has to be done based on the season and the water requirement of the plant

So, the correct answer is 'By watering optimum quantities regularly'

Which of these methods does not result in conservation of water?

  1. Using drip irrigation

  2. Recycling of water

  3. Cutting vegetation so that less water is lost by transpiration

  4. Planting more trees
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Conservation is the process in which the resources are used in a sustainable manner without affecting the environment. The water resources can be conserved by using drip irrigation which reduces the wastage of water. Recycling of water will help allow usage of the waste water for non-drinking purposes. Afforestation includes planting of more trees increasing the amount of rainfall. Thus, the correct answer is option C.

A large population affects water resources adversely due to  _____.

  1. Building of dams

  2. Digging of canals

  3. Prayers offered for rain

  4. Higher food grain production
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water scarcity may be an outcome of large and growing population and consequent greater demands for water, and unequal access to it. A large population means more water not only for domestic use but also to produce more food. Hence, to facilitate higher food-grain production, water resources are being over-exploited to expand irrigated areas and dry-season agriculture.
