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

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.

Explanation

'Catch it where it falls'  is the basic idea behind the rain water harvesting. Rain water harvesting is the accumulation and storage of rain water for reuse on site rather than allowing it to run off.

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.

Providing water to irrigation process is an advantage of creating dam.

Multiple choice biology structure of earth electricity from water energy hydro electricity hydro energy

Which of the following is an advantage of building dams?

  1. The dams disturbs aquatic life

  2. Dams lead go large scale disturbance of aquatic life

  3. It disturbs the natural ecosystem

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

The dams across the Rivers can disturb the aquatic life and can lead to their large scale destruction the fishes and other water animals may enter the power generation turbines where they may get crushed.

Multiple choice physics sources of energy electricity from water energy hydro electricity hydro energy

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.

Multiple choice chemistry adsorption and colloids applications of colloids colloids around us the colloidal state

Silver iodide is used for producing artificial rains because $AgI$:

  1. is easy to spray at high altitude

  2. is insoluble in water

  3. is easy to synthesize

  4. has crystals similar to ice
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solid silver iodide is preferred as a nucleator for artificially stimulated rain because its crystal lattice parameters are close to those of ice, and for that reason are more effective than other salts in causing small ice crystals in clouds to melt.
