Which of the following is a traditional way to conserve water?

  1. Tube wells

  2. Bawris

  3. Rainwater harvesting

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

This is the old method of rain water storage and recharge. In olden days people built deep step wells into the ground. These deep step wells are called the Bawris. During rainy season these wells are filled with water. The water is stored in these wells for a long time because they are very deep and the evaporation of water becomes less.

Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Rainfall pattern depends on

  1. The underground water table

  2. The number of water bodies in an area

  3. The density pattern of human population in an area

  4. Prevailing season in an area
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Rainfall pattern depends on the number of water bodies in an area because which area has more water bodies that area evaporates more water and this evaporation increases the precipitation water cycle and hence initiate  the rainfall 

So option 'b' the number of water bodies in an area is the correct answer.

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

What is the cause of a very high demand of water even though it is inexhaustible natural resource?

  1. Fresh water makes only small volume of world's water

  2. Most of the fresh water is in the form of ice and snow cover

  3. Conversion of sea water to fresh water is difficult and not economical

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water is inexhaustible natural resource .i.e. it is never going to deplete but it has a very high demand because the large percentage of water which is present on the Earth surface is not suitable for drinking. The suitable form is in the frozen form (ice, snow, glaciers etc). Its conversion to drinking water is non-economical and hence is not favoured.

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

Why is water a renewable resource?

  1. Water continuously evaporates.

  2. Man can create water.

  3. Use of water is minimum.

  4. The above statement is incorrect.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources) fuel and conservation

_____ is a method of conservation of water.

  1. Rainwater harvesting

  2. Rainwater dropping

  3. Rain planning

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

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit, a reservoir with percolation. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, indoor heating for houses, groundwater harvesting.

Which one of the following is not an ideal solution for tackling water shortages?

  1. Controlling population growth

  2. Conserving water in irrigation

  3. Controlling water pollution

  4. Drilling large number of deep bore wells
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Drilling large number of deep bore wells,

It is not an ideal solution for tackling water shortage.
Rain water harvesting and ground water recharging is the need of the hour. Roof top rain water harvesting are being taken up in urban areas. In roof top harvesting u r to collect rain water and  using a filter clean it, then send it to the aquifer through a tube well or dug well. In open field u can recharge ground water storing the rain water in numerous tanks, ponds, contour  trench etc disallowing the rain water to drain to river and finally to ocean. If  tube wells are drilled inside the tanks and  ponds, more rain water can be recharged into the aquifer.

Floods can be prevented by:

  1. afforestation

  2. cutting the forests

  3. filling the land

  4. removing the top soil
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Afforestation means planting trees. 

As we know, the roots of the trees help to hold soil layer firmly.

It is evident that it helps not to make soil loose and prevents erosion. Thus, by planting more and more trees, the top layer of soil becomes less prone to erosion by wind, water or anything likely. 

Thus, it prevents erosion and helps in soil conservation.

Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface runoff. This reduces a rivers discharge and so makes it less likely to flood.

Option A is correct.
