A Correct answer
Explanation

Ozone is a protective blanket that is present in the stratosphere which protects earth from harmful effects of UV radiations that are present in sunlight.

Chlorofluorocarbons and other halogenated compounds cause ozone depletion.

Formation of ozone hole is maximum over _____________.

  1. India

  2. Australia

  3. Antarctica

  4. Europe

C Correct answer
Explanation

Ozone is a protective blanket that is present in stratosphere which protects Earth from harmful effects of UV radiations that are present in sun light.

Ozone holes are formed in Antarctica and these are due to special clouds that form in the stratosphere called polar stratospheric clouds. Clouds usually do not form in stratosphere, this can happen only at such low temperatures. These clouds accumulate pollutants resulting in formation of ozone holes.

Ozone depletion generally occurs in ________.

  1. Biosphere

  2. Atmosphere

  3. Stratosphere

  4. Microsphere
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Stratosphere is the region of atmosphere where ozone layer is present, hence ozone depletion occurs in stratosphere.
  • Biosphere is the region of surface and atmosphere of earth occupied by living organisms, hence unrelated to the question.
  • Atmosphere is a broad term which becomes irrelevant when already a specific option ie stratosphere, is given in the choices.
  • Microsphere is a small particle which has a different environment than its surroundings, hence incorrect.

Global warming mainly caused by ___________.

  1. greenhouse gases

  2. global gases

  3. green gases

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

The greenhouse is the body which allows the shortwave incoming solar radiation to come but does not allow the longwave outgoing terrestrial infrared radiation to escape. Carbon dioxide, water vapour etc are the main gases of the greenhouse. The amount of greenhouse gases is increasing day by day which causes the increase of the temperature of the earth. In this way, global warming mainly caused by greenhouse gases.

Identify the primary cause of global warming.

  1. Emission of $CO _2$

  2. Emission of $O _2$

  3. Both a and b

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

Global warming refers to a gradual rise in atmospheric and ground surface air temperature. Emission of Carbon dioxide is one of the primary cause of global warming. As this gas allows the shortwave incoming solar radiation but does not allow the longwave outgoing terrestrial infrared radiation to escape. Thus an increase of carbon dioxide gas also increases in temperature of the earth which causes global warming.

Destruction of ozone is ________ cause of global warming.

  1. Primary

  2. Secondary

  3. Tertiary

  4. None of these

B Correct answer
Explanation

Secondary,

The ozone layer prevents most harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals.

Ozone destruction is caused by mainly _________.

  1. Methane

  2. Nitrous oxide

  3. Both A and B

  4. None of these

C Correct answer
Explanation

Methane and Nitrous oxide.

The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).

Which one of the following contributes to the greenhouse effect?

  1. Oxygen

  2. Nitrogen

  3. Argon

  4. Carbon dioxide
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Carbon dioxide,

The major greenhouse gases (GHG’s) solely responsible for the greenhouse effect are Carbon dioxide, Ozone, Methane, and Water vapor. Although these gases comprise 1% of our atmosphere, they act like a thick warm blanket outside that surrounds this planet and regulate climate control. Greenhouse effect is not bad. In fact, it is needed for all of us to survive on planet Earth. In short, the greenhouse effect is nothing but a naturally occurring process designed by nature that aids in heating the earth’s surface and helps to maintain ecological balance.
