Air Pollution Questions

Multiple choice geography environmental changes atmosphere as a green house global warming and climate change energy from the sun

Which gas is responsible for the depletion of ozone layer?

  1. Carbon dI oxide

  2. Methane

  3. Cluroflorocarbon

  4. Sulphur di oxide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Chlorofluorocarbons (CFCs
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).
Multiple choice zoology bio-geo chemical cycles in nature nutrient cycles- flow of substances carbon cycle biogeochemical cycles - gaseous

The ozone at ground level is primarily from__________ precursors

  1. Fossil fuel
  2. $CFC _{S}$

  3. Oxygen

  4. Methane
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ground-level ozone is a secondary pollutant formed by the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight, both of which are primarily emitted by fossil fuel combustion.

Multiple choice geography the biosphere alternatives for minimising depletion of natural resources components of environment effects and successes of environment conservation

Acid rains are produced by _________.

  1. excess $NO _2 and SO _2$ from burning fossil fuels
  2. excess production of $NH _3$ by industry and coal gas

  3. both a and b

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

Acid rain is primarily caused by the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels, which react with water vapor in the atmosphere to form sulfuric and nitric acids.

Multiple choice evs - i the environment and us ways to prevent air pollution ways to reduce air pollution reducing air pollution

Air pollution is caused by:

  1. human.

  2. nature.

  3. both nature and man.

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

Air pollution could be both due to natural or man-made causes. The major factors affecting composition of air are: area of forests in the region (potential cause of forest fires), industries present in the area, density of population, urbanization, etc.

Multiple choice economics environment pollution strategies to control environmental pollution strategies to control pollution strategies to control environmental pollution and green chemistry

Acid rain is caused by _____ .

  1. industries

  2. power plants

  3. automobiles

  4. all of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rainfall made so acidic by atmospheric pollution that it causes environmental harm, chiefly to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulphur and nitrogen oxides which combine with atmospheric water to form acids.
These gases are released by automobiles, industries, power plants etc.

One way of preventing pollution of the air is by passing exhaust gases through a filter. Glass fibre or silicone-treated bags of textile material are used for filtering.

  1. Hot gases

  2. High pressure gases

  3. Cold gases

  4. Reactive gases
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silicone coated fiberglass bags are resistant to high temperatures and are able to separate at a temperature range of approximately $-50^oC$ to $+250^oC$. Thus it has excellent weather proof and water repellent properties. It is also resistant to chemicals. It is used to filtering hot gases as it can withstand high temperatures.

Multiple choice zoology garbage in, garbage out plastic waste recycling of paper thermocol

Air pollution can be caused by

  1. Burning of paper

  2. Burning of plastic

  3. Recycling of plastic

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

Burning paper and plastic releases harmful gases and particulate matter into the atmosphere, contributing to air pollution. Recycling processes can also involve emissions.
