Among the following compounds, which one is not responsible for the depletion of ozone layer?

  1. $CH _4$
  2. $CFCl _3$
  3. $CHCl _3$
  4. $Cl _2$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The details of polar ozone hole formation differ from that of mid-latitude thinning but the most important process in both is catalytic destruction of ozone is by atomic halogens. 

The main source of these halogen atoms in the stratosphere is photo dissociation of man-made halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbon (CFCs), HCFCs, freons, halons). These compounds are transported into the stratosphere by winds after being emitted at the surface.

So, $C{ H } _{ 4 }$ does not contain a halogen therefore it is not responsible for the depletion of ozone layer.

Multiple choice business organisation and correspondence industrial pollution and degradation of environment pollution and industrial pollution pollution and its type pollutions

Pollutant gases have an adverse effect on the environment and on our health. The amount of these gases has been steadily increasing over the years. The table given below shows the source and the amount of some pollutant gases produced by human activities.

Pollutant Gas Source Amount Produced per Year(Millions of Tonnes)
$CO _2$ Vehicle exhaust furnaces, burning coal 350
$SO _2$ Oil industries 200
$NO _2$ Vehicles exhaust furnaces 55
Hydrocarbons Vehicle exhaust furnaces, industries 90

Which one of the following statement(s) is correct ?

  1. The total sulphur dioxide and nitrogen dioxide produced per year is 145 million tonnes.
  2. $CO _2$ is produced by industries.
  3. The combined total pollutant gases produced by $NO _2$ and hydrocarbons is less than the total pollutant gases produced by $SO _2$

  4. Hydrocarbons are produced by vehicle exhaust gases and industries.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

NO2 (55) + Hydrocarbons (90) = 145. SO2 = 200. Since 145 < 200, statement C is correct. Statement A is incorrect because 200 + 55 = 255, not 145.

Multiple choice zoology environmental pollution primary air pollutants air pollution - types and sources not for breathing not for drinking

Which of the following will not cause an environmental pollution?

  1. Noise from vehicles

  2. The Using of chemical fertilizers

  3. Improper disposal of sewage

  4. The Using of a CFC free refrigerator
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The noise from the horn and engines of the vehicles results in sound pollution. The use of extensive chemical fertilizers causes accumulation of these chemicals in the soil and leaching into the ground water. The runoff of these chemicals into water causes water pollution. The improper disposal of sewage results in water pollution. The use of CFC-free refrigerator does not cause any air pollution.

Thus, the correct answer is option D.
