What is rainwater harvesting?

  1. collecting, storing and distributing rainwater

  2. seeding in clouds

  3. distribution of stored water

  4. water supply
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rainwater harvesting is the process of collection of rainwater from surfaces on which rain falls, filtering it and storing it for multiple uses  'OR' the method of collecting, storing and distributing rainwater for different uses. 

The collected water can be stored for direct use or it can be diverted for groundwater recharge.

Which of the following situations is classified as suffering from water scarcity?
(a) Region with high annual rainfall.
(b) Region having high annual rainfall and large population.
(c) Region having high annual rainfall but water is highly polluted.
(d) Region having low rainfall and low population. 

  1. a and b

  2. a and d

  3. c and d

  4. b and c
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Region having high annual rainfall and large population and  Region having high annual rainfall but water is highly polluted regions have high water scarcity problem because of high use of water tends to water pollution.Polluted water is unusable for humans.

Where can rain water harvesting not be practised?

  1. Playground

  2. Rooftops

  3. Bathroom

  4. Can be used in all of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rainwater harvesting cannot be practiced in Bathroom as the bathroom is a closed area and the rain water cannot directly comes into it.

As all other are open area where rain water directly falls so there we can practice rainwater harvesting

Where can Rain Water Harvesting be implemented?

  1. Homes

  2. Schools

  3. Any other space as long as there is a catchment area

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rainwater harvesting can be implanted in an open area where the rain falls directly.

so it  can be implanted in any space as long as there is a catchment area.
As it cannot be implanted in closed area so it cannot be implanted in homes and schools.

Rain water harvesting is a method employed to:

  1. stop soil erosion

  2. raise the water table

  3. increase afforestation

  4. decrease floods and droughts

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

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. All the water was collected into a well and helps in raising water table.

Multiple choice social science waste generation and management origin of waste products e-wastes waste generation waste and its types

Waste of water can be minimised by 

  1. Reuse of water

  2. Wasting the water during brushing

  3. Using more water for showers and toilets

  4. Both A and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water resources are limited in an ecosystem. There is an urgent need to minimize the waste of water. It can be done by either reuse or recycle of water. Recycling of water can be done by purifying waste water and reusing again for another purpose. The various ways to reuse water is using treated water for toilet flushing, in agriculture, for industrial processes, etc.

Thus, the correct answer is option A.

Construction of dams

  1. Is always an advantageous process

  2. Has only disadvantages

  3. Both

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

The construction of dams for generating hydro electric power and then installation of transformers and their connection to the national grid has the following four main advantages:

A) disturbance of the natural ecosystem in the surrounding forest area

B) disruption of the plants and animals life

C) displacement of people on a large scale

D) disruption of the aquatic ecosystem.

So,construction of dams is not always advantageous.
