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.

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

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.

The release of chlorofluorocarbons by the use of refrigerators, air conditioners, deodorants, etc., are destroying the ________ layer of the atmosphere.

  1. Mesosphere

  2. Ionosphere

  3. Humidity

  4. Ozone

D Correct answer
Explanation

D. Ozone

When the CFC refrigerants are leaked from refrigeration or air-conditioning systems, they drift around the lower layers of the atmosphere. Slowly they start infiltrating into the upper layers of the atmosphere and soon reach the ozone rich stratosphere, where they undergo major chemical changes.

The phenomenon caused due to the use of fossil fuels is _______________.

  1. greenhouse effect

  2. earthquakes

  3. ozone depletion

  4. environmental imbalance

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When the industrial revolution started, the level of $CO _2$ in the atmosphere was around 280 parts per million by volume but that has risen to around 380 ppmv due to our burning of fossil fuels. Because of tremendous rise in $CO _2$ (about 35% rise) the global warming scenario has been deteriorated or faster. The melting of arctic ice, severe climate changes are some of the effects among many, of the global warming. Inefficiency in the use of fossil fuels which increased the $CO _2$ level by 17%.

Carbon dioxide and some other gases trap the heat radiated by the earth and cause ________.

  1. Global warming

  2. Ozone depletion

  3. Greenhouse effect

  4. Acid rain

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The greenhouse effect occurs when gases like carbon dioxide trap heat in the atmosphere, preventing it from escaping into space, which leads to warming.
