Weekly Quiz Competition

Question 1
1 / -0

Minerals and metal are:

A
Biodegradable resources

B
Renewable

C
Non-renewable

D
Renewable and non-renewable resources
Solution
- Biodegradable resources are the ones that can be broken down into simpler substances by the action of microbes.
- Renewable resources are the ones that can be replenished in nature over a period of time.
- Non renewable resources are the ones that can not be replenished in nature over a period of time or they may be replenished but over a very longer period of time.
Minerals are considered to be renewable resources whereas metals are considered to be non-renewable resources.
So, the correct answer is 'Renewable and non-renewable resources'.
Question 2
1 / -0

Assertion: Ozone is destroyed by CFCs in the upper stratosphere.
Reason: Ozone hole increases the amount of UV radiation reaching the earth.

A
Assertion and reason are correct , but the reasons is not the explanation for the assertion

B
Assertion is false, but the reason is correct

C
Assertion and reason are incorrect, Assertion and reason are both correct

D
And the reason is the correct explanation for the assertion

Solution

The upper stratosphere consists of ozone $$(O_3)$$, which protect us from harmful ultraviolet (UV) radiations coming from the sun.
When CFC reacts with ozone it breaks the molecule of ozone resulting in ozone layer depletion.
Question 3
1 / -0

Which process takes place in winters when the snow falls?

A
Evapo-transpiration

B
Condensation

C
Precipitation

D
Transpiration

Solution

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. During winters, the atmosphere is cold and thus rather than rain, the droplets freeze and fall in the form of snow.
Question 4
1 / -0

Earth is protected from UV-radiations by:

A
ozone layer

B
nitrogen layer

C
carbon dioxide

D
oxygen layer

Solution

The ozone layer refers to a region of earth's stratosphere that absorbs most of the sun's ultraviolet (UV) radiation.
It contains high concentration of ozone ($$O_3$$).
Question 5
1 / -0

Water enters atmosphere by

A
Filtration

B
Evaporation

C
Precipitation

D
Weathering

Solution

Evaporation is the process by which water from all the water bodies and land evaporates to form water vapours and enter the atmosphere to form clouds.
The correct option is B.
Question 6
1 / -0

Evaporation is a _____________ process.

A
Cooling

B
Heating

C
Can't tell - it depends on the temperature

D
Both A and C

Solution

Evaporation is a process in which heat is required to convert water into water vapour.
The correct option is B.
Question 7
1 / -0

Air pollution can lead to:

A
Acid rain

B
Heart diseases

C
Allergies

D
All of the above
Solution
- Air pollution refers to the increased amount of harmful substances in the air like suspended particles of unburnt carbon and hydrocarbons in the air, oxides of nitrogen and sulphur, etc.
- There are several adverse effects of air pollution.
- Acid rain which is caused when the oxides of nitrogen and sulphur combine with rainwater and become acidic can harm the building and monuments and can cause skin cancer and allergies.
- Regular breathing of polluted air can lead to allergies, heart diseases, and cancer.
- Also, the suspended particles in the air can lead to various respiratory troubles.
So, the correct option is 'D'.
Question 8
1 / -0

All forms of water that comes down on the earth, including rain, snow, hail, etc. is known as ____________.

A
Evaporation

B
Condensation

C
Precipitation

D
Accumulation

Solution

When the condensed water particles in the atmosphere combine with dust particles and become heavy, they form clouds. These particles then fall back on the earth's surface in the form of rain, snow, sleet, hail, etc.
So, the correct option is 'C'.
Question 9
1 / -0

Earth's temperate is affected by:

A
The loss of precipitation

B
The loss of heat

C
The loss of evaporation

D
The loss of sunlight

Solution

The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space. Think of the moon, which is about the same distance from the Sun that the Earth is. Despite that, on the surface of the moon, with no atmosphere, the temperature ranges from –190° C to 110° C.
So, if there were no atmosphere, loss of heat would highly affect earth's temperature.
Question 10
1 / -0

What would happen if earth had no atmosphere?

A
Earth would be below freezing

B
There would be no existence

C
There would be no length of the day

D
All of above

Solution

If there were no atmosphere, there would be no existence of life. Examples are Venus and Mars.
