Question 1
1 / -0

Water that moves over the surface of the ground into lakes and rivers is called

A
ground water

B
a water table

C
run-off

D
the water cycle

Solution

The run-off process leads water towards lakes and rivers.
Option C is correct.
Question 2
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 3
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 4
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 5
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 6
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 7
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 8
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 9
1 / -0

The water table is reduced below the ground due to:

A
continuous use of groundwater

B
increase in rainfall

C
construction of amusement parks

D
increase in pollution

Solution

It is because the groundwater is continuously used. Also rainfall occurs for short spells of high intensity. Because of such intensities and short duration of heavy rains, most of the rain falling on the land flows away rapidly, leaving very little water for the recharge of underground water.
Question 10
1 / -0

The water found below the water table is called _____________.

A
rock water

B
groundwater

C
underwater

D
both B and C

Solution

The water found below the water table is called groundwater. It is found under the ground in the cracks and spaces in soil, sand and rock.
