  3. Fungi

  4. Hydrocarbon gases
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hydrocarbons are nonbiodegradable pollutants. They are a type of secondary pollutants. They are very dangerous for life. Hydrocarbons are produced naturally as well as due to incomplete combustion of the fuels. They are the major cause of respiratory disorders. Man used fuel for their own purpose with releases harmful gasses and causes pollution.

The lowest region of atmosphere is known as

  1. Stratosphere

  2. Ozonosphere

  3. Troposphere

  4. Mesosphere
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The atmosphere comprises of layers based on temperature. Each layer has a specific composition of gases. These layers are the troposphere, the stratosphere, mesosphere and thermosphere. All these layers are placed to a different level from the earth. 

The troposphere is the lowest layer of the Earth's atmosphere. It starts at Earth's surface and goes up to a height of 7 to 20 km above sea level. Most types of clouds are found in this region, and almost all weather occurs within this layer. It holds nearly all of the water vapor in the Earth's atmosphere, regulates temperature and produces weather. Hence option C is correct.

Which of the major sources of air pollution contributes pollutants like chlorofluorohydrocarbons?

  1. Industrial effluents

  2. Aerosols

  3. Sewage pollutants

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The presence of CFCs in the atmosphere results in the depletion of the ozone layer. They are used as coolants in refrigerators, aerosol sprays, coolers, etc. The increase in the concentration of the chloro- fluoro-hydrocarbon molecules in the atmosphere results in air pollution. 

Thus, the correct answer is option B.

Classical smog is

  1. Dark brown smog

  2. Yellow brown smog

  3. Los Angeles smog

  4. Smog with secondary pollutants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Smog is the fog containing smoke. Smog is of two types depending upon the type of pollutants; classical smog and photochemical smog.
  • Classical smog is formed when there is high concentration of sulphur dioxide and particulate matter produced due to combustion of fuels. It occurs in cold and humid climate. It is also known as London smog or Sulphurous smog and causes dark brownish colour of atmosphere.
  • Photochemical smog is formed when sunlight acts on the oxides of nitrogen and hydrocarbons produced from factories or by automobiles. It occurs in warm and dry climate. It is also known as Los Angeles smog and causes light brownish colouration of atmosphere.
So, the correct answer is 'Dark brown smog'.

Which of the following is NOT caused by Hydrogen sulfide pollution in the air?

  1. Mottled chlorosis

  2. Defoliation in plants

  3. Decolouration of paints

  4. Cardiovascular malfunction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In human, effect of Hydrogen sulfide due to air pollution is not seen but in plant it greatly effect like chlorosis ( yellowish color of plant leaves). Falling of leaves is also a major problem (defoliation). Hydrogen sulfide also damage building, bridge paints (discoloration).

So correct option is 'cardiovascular malfunction'.

Air pollution is likely to be most severe

  1. in the interior of continents

  2. near the center of an anticyclone

  3. in the summer

  4. when the atmosphere is turbulent
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Anticyclones are high-pressure systems characterized by sinking air and stable atmospheric conditions. This stability traps pollutants near the ground, leading to severe air pollution.
