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.

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'.

  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'.
