Question 1
1 / -0

As we go up the layers of the atmosphere, the pressure ________.

A
Increases

B
Decreases

C
Remains the same

D
All of these
Solution
- The weight of the atmosphere acts as a force upon the underlying surface of the Earth. The amount of force exerted over an area of the surface is called atmospheric pressure or air pressure.
- In the atmosphere, the air pressure at any point is caused by the weight per area of the air above that point.
- As we go up the layers of the atmosphere, fewer air molecules are above us. So, there will be less weight of air above us. Hence, atmospheric pressure always decreases as we move upward in the atmosphere.
Thus, option D is correct.
Question 2
1 / -0

When precipitation comes down to the earth in the liquid form, it is called

A
Cloud

B
Rain

C
Snow

D
Water
Solution
Precipitation is part of the water cycle.
In the water cycle, water from oceans, lakes, swamps, rivers, plants can turn into water vapor.
Water vapor condenses into millions of tiny droplets that form clouds.
Clouds lose their water as rain or snow, which is called precipitation.
When precipitation comes down to the earth in liquid form, it is called rain.
People rely on precipitation for fresh water to drink, bath, and irrigate crops for food.
So the correct answer is option B.
Question 3
1 / -0

Generally, the warm ocean currents originate near the ___________.

A
Poles

B
Equator

C
Tropics

D
Temperate zone

Solution

The equatorial region is hot and light and polar regions are cold and heavy. So, the warm ocean currents originate near the equator and flow towards the polar region.
Question 4
1 / -0

The ozone layer is affected because of chemicals called __________.

A
Environmental

B
Carbon dioxide

C
Chlorofluorocarbons

D
Nitrogen

Solution

Chemicals like CFCs are unstable and react with the ozone layer in the atmosphere. This affects the ozone layer and results in its depletion.
The correct option is C.
Question 5
1 / -0

With the rise of water temperature, dissolved oxygen

A
Remains unchanged

B
Increases in amount

C
Decreases in amount

D
Is more available to the aquatic organisms

Solution

Dissolved oxygen is the free oxygen in the liquid. It is the form which is not present in combined form with any compound and can be available for the organisms in the aquatic environment. When there is rise in temperature, the dissolved oxygen starts to react with the other molecules. This results in the formation of compounds. The rise in temperature causes decrease in the level of dissolved oxygen.
Thus the correct answer is option C.
Question 6
1 / -0

A glass of water with some pieces of ice in it, after some time, small drops of water forms on the outer surface of the glass. This process is called as

A
Evaporation

B
Precipetation

C
Condensation

D
None of the above

Solution

This process is called condensation.
This happens because when the cold glass touches the hot air around, the water vapour in the air condense and form droplets on the surface of glass.
Question 7
1 / -0

The rate of evaporation depends on

A
Temperature

B
Volume of water

C
Wind movement

D
All of the above

Solution

Temperature, volume of water and wind movement are the major factors that determine the rate of evaporation.
Thus, the correct option is D- 'All of the above'.
Question 8
1 / -0

The opposite of evaporation is

A
Transpiration

B
Condensation

C
Precipitation

D
Freezing

Solution

Condensation is formation of water from water vapours while evaporation is formation of water vapours from water.
Thus, the correct option is B.
Question 9
1 / -0

Which of the following is a recently originated problem of environment?

A
Global warming

B
Ozone depletion

C
Greenhouse effect

D
All of these

Solution

Global warming is the gradual warming of the earth's surface and atmosphere that causes a change in the earth's climate. It is due to the increase of greenhouse gases like carbon dioxide in the atmosphere. Ozone layer depletion is thinning of the protective ozone layer in the stratosphere. Its depletion is a result of CFC emission and pollution. The greenhouse effect is the process in which the radiation from a planet's atmosphere is unable to escape and rather warms the planet's surface to a higher temperature. Thus, all three problems are man-made and have recently come into existence. Hence, option D is correct.
Question 10
1 / -0

Today we are using natural resources maximumly. Which of the following options correctly explain the natural resources?

A
Resources not made by humans but nature and are used by all living organisms.

B
Resources are made by humans and used by all living organisms.

C
Resources are made naturally but not used by any organisms

D
None of the above

Solution

Natural resources are resources which exist without the actions of humankind. These resources are available in nature and are used by the living organisms for the benefit of the mankind. The common natural resources are sun, forests, tides, wind, etc.
Thus, the correct answer is option A.
