Question 1
1 / -0

________ is the major source of fresh water.

A
Groundwater

B
Sea-water

C
Lake

D
None of the above

Solution

Groundwater and surface waters are the major sources of fresh water in India. Groundwater is the water present beneath the earth's surface which can be extracted in various ways.
Question 2
1 / -0

The main source of water for rivers is in the form of :

A
Lakes

B
Rain water

C
Snow

D
Dams

Solution

The main source of water for perenial rivers is in the form of $$snow$$. This is because during summer season, all the snow will melt which acts as a source of water and during winter season there is snowfall itself.
Question 3
1 / -0

Water harvesting is done by ____________ processes.

A
rainwater

B
groundwater

C

both A and B

D
atmospheric water

Solution

Water Harvesting
It means storing rain where it falls or storing the run off in your own village or town. And taking measures to keep that water clean by not allowing polluting activities to take place in our locality.

It can be done by two major processes:
1. Rainwater harvesting
It is a method of collection and storage of rainwater into natural reservoirs or tanks or the infiltration of surface water into subsurface aquifers.
2. Groundwater harvesting
Groundwater harvesting is a method to save water placed under the ground to control the groundwater flow in an aquifer and to raise the water table.
Question 4
1 / -0

The percentage of water in a human body is:

A
80%

B
70%

C
60%

D
50%

Solution

The percentage of water in the human body is $$70\%$$.
Different parts of the body contain different percentages of water and the average $$\approx 70\%$$.
Question 5
1 / -0

Which of the following is the most important factor in balancing the amount of fresh water on earth?

A
Water cycle

B
Green house effect

C
Wastewater treatment plants

D
Transpiration

Solution

Out of all the options, option $$\text{A}$$ is correct as water cycle is the most important factor in balancing the amount of fresh water on earth.
Question 6
1 / -0

Which of the following water sources is used for drinking purposes?

A
Sea water

B
Glaciers

C
Ground water

D
None of these

Solution

Groundwater is, in general, easier and cheaper to treat than surface water, because it tends to be less polluted and hence used for drinking purposes.
Sea-water contains dissolved salt in it, hence it is not generally used for drinking purposes as it's very difficult to purify. Water stored in the form of glaciers mostly gets dissolved into seawater after melting rendering it unfit for drinking.
Hence, the answer is C.
Question 7
1 / -0

Study the figure below showing the components of water cycle represented by P, Q, R, S, T.
Which of the following can be harnessed to conserve rain water?

A
Q, S

B
P, Q

C
P, S

D
S, T

Solution

Only run-off ($$Q$$) part of the precipitated ($$P$$) water can be harnessed to conserve rainwater.
Option $$B$$ is correct.
Question 8
1 / -0

Groundwater is an example of a/an:

A
non-renewable resource

B
exhaustable resource

C
renewable resource

D
degradable resource

Solution

The resources which renew themselves over time are termed renewable resources. After a heavy shower, most of the water percolated into the ground through pores on the surface and recharges the groundwater level. But the rate of recharging of groundwater is slower than the rate at which it is being used up. If proper measures are not taken to save groundwater, it might soon become a non-renewable resource.

So, technically groundwater is a renewable resource, but the process of recharging groundwater is pretty slow.
Question 9
1 / -0

How can we conserve water?

A
Turn off the water while brushing your teeth.

B
Take shorter showers.

C
Water your lawn only when it needs it.

D
All of the above are correct.

Solution

Water is the most important element for the preservation of life. Water is a finite commodity that, if not managed properly, will result in shortages soon. Water conservation can go a long way to help alleviate these impending shortages.
Question 10
1 / -0

Water does not contain mineral salts of:

A
sodium

B
gold

C
calcium

D
magnesium

Solution

The principal ions found in water are calcium, magnesium, sodium, bicarbonate, sulfate, chloride and nitrate. A few parts per million of iron or manganese may sometimes be present and there may be traces of potassium salts, whose behaviour is very similar to that of sodium salts.
