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.

How is water conserved when evaporation is reduced?

  1. Low temperature

  2. Low wind speed

  3. Both (A) and (B)

  4. High temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation is a physical process influenced by environmental conditions. Lower temperatures reduce the kinetic energy of water molecules, and lower wind speeds reduce the rate at which water vapor is carried away from the surface.

Which one is not a beneficial effect of water conservation?

  1. Reduction in water loss

  2. Reduction in water fall

  3. Reduction in waste of resources

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

Water conservation aims to reduce waste and loss. A reduction in 'water fall' (precipitation) is a natural climatic event, not a beneficial effect of human water conservation efforts.

The component of rainwater harvesting system is

  1. Conduits

  2. Dam

  3. Lake

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowing it to run off. These stored waters are used for various purposes such as gardening, irrigation, etc.
  • The components of the rainwater harvesting system include  Catchments, Coarse mesh, Gutters, Conduits, First-flushing,  Filter, Storage facility.
  • Conduits are pipelines or drains that carry rainwater from the catchment or rooftop area to the harvesting system. Conduits can be of any material like polyvinyl chloride (PVC) or galvanized iron (GI), materials that are commonly available.
  • Hence Conduits are the component of the rainwater harvesting system.
  • So, the correct answer is 'Conduits'.

Identify the types of rainwater harvesting method.

  1. Roof top

  2. Run off

  3. Dam

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowing it to run off. 
  •  These stored waters are used for various purposes such as gardening, irrigation, etc.
  • Broadly there are two ways of harvesting rainwater. They are Surface runoff harvesting and Rooftop rainwater harvesting.
  • Hence Rooftop and runoff are the types of rainwater harvesting methods.
  • So, the correct answer is 'Both A and B'.

Water contains impurities during

  1. Evapo-transpiration

  2. Condensation

  3. Transpiration

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

Condensation is the process where water vapor turns into liquid water. As water vapor condenses into droplets in the atmosphere, it often collects dust and other atmospheric particles, resulting in impurities.
