Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water conservation involves multiple strategies, including reducing waste, improving irrigation efficiency, and recycling industrial water. Therefore, all listed options are correct.

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

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. 

Multiple choice geography water bodies importance of water and water bodies study of hydrosphere and water bodies water bodies and conservation

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. 

Multiple choice geography water bodies importance of water and water bodies study of hydrosphere and water bodies water bodies and conservation

Collecting rainwater on the roofs of building and storing it underground for later use is called as _____.

  1. Water cropping

  2. Rainwater harvesting

  3. Lake

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rainwater harvesting is the process of collecting and storing rainwater from surfaces like roofs for future use, especially in areas with water scarcity.

Multiple choice geography water bodies importance of water and water bodies study of hydrosphere and water bodies water bodies and conservation

Water collected from rooftop water harvesting system was directed into _____.

  1. Ponds

  2. Lakes

  3. Underground tanks

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

i) In semi-arid and arid regions of Rajasthan almost all the houses traditionally had underground tanks for storing drinking water. They are extremely reliable source of drinking water when other sources are dried up. This is considered the purest form of natural water.

(ii) The tanks can be as large as big rooms.

(iii) The tanks were part of the well-developed rooftop rainwater harvesting system.

(iv) The tanks were built inside the main house or the courtyard giving cooling effect to the rooms in the summer.

 (v) Those tanks were connected to the sloping roofs of the houses through a pipe.

(vi) Rain falling on these roof tops would travel down the pipe and stored in these underground tanks.

(vii) Usually first rain water is not collected to clean the roof top and the pipe.

Multiple choice geography water bodies importance of water and water bodies study of hydrosphere and water bodies water bodies and conservation

Rainwater is collected in tanks in almost all _____.

  1. Seasons of Rajasthan

  2. Only in winter season

  3. The houses of Rajasthan

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the semi-arid and arid regions of Rajasthan, particularly in Bikaner, Phalodi and Barmer, almost all the houses traditionally had underground tanks or tanks for storing drinking water.

A deficiency in ______ for successive years result in serious water shortages. 

  1. Monsoon rainfall

  2. Winter rainfall

  3. Summer heat

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In many regions, especially those dependent on agriculture, a deficiency in monsoon rainfall for successive years leads to drought and severe water shortages.

Multiple choice evs receding water table water resources and conservation water conservation and irrigation water a precious resource

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.

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

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'.
Multiple choice chemistry water: a natural resource water resources and conservation receding water table water conservation and irrigation

Water scarcity is caused due to:

  1. population growth

  2. water cycle

  3. non-melting of snow

  4. rain fall
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The population is a major cause of water shortage. Water is polluted when industrial wastes are deposited into water bodies thus making it unfit for human consumption. Thus there is a need for water security.

Multiple choice chemistry water: a natural resource water resources and conservation receding water table water conservation and irrigation

Under or non-availability of usable water is called:

  1. purification of water

  2. pollution of water

  3. rationing of water

  4. scarcity of water
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Scarcity of water is the under or non-availability of usable water. This water presence in the ground is very less and this may sometimes lead to draughts.
