Questions Related to water resources and conservation

Water can be conserved by

commercial applications receding water table water and ocean conservation water resources and conservation water conservation and irrigation

  1. Avoiding its wastage

  2. Using better methods of irrigation

  3. Recycling water in factories

  4. All of the above

Show answer
Correct Option: D

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

commercial applications receding water table water and ocean conservation water resources and conservation water conservation and irrigation

  1. Using drip irrigation

  2. Recycling of water

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

  4. Planting more trees

Show answer
Correct Option: C
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.

The component of rainwater harvesting system is

social science water a precious resource water resources and conservation receding water table water conservation and irrigation

  1. Conduits

  2. Dam

  3. Lake

  4. None of the above

Show answer
Correct Option: A
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

Show answer
Correct Option: D
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'.
