  1. $33^o C$

  2. $34^o C $

  3. $35^oC$

  4. $36^oC$

Show answer
Correct Option: A
Explanation:

On Earth, naturally occurring amounts of greenhouse gases have a mean warming effect of about $33^ \circ C$.


Hence the correct option is A.

  1. Asia

  2. Africa

  3. Europe

  4. Australia

Show answer
Correct Option: A
Explanation:

Majority of people living in regions which are threatened by global warming are in Asia.

What causes the global warming?

  1. Burning of fossil fuels

  2. Deforestation

  3. Industrialization

  4. All of the above

Show answer
Correct Option: D
Explanation:

Global warming is the slow increase in the average temperature of the earth’s atmosphere because an increased amount of the energy 
All the given activities increases the amount of green house gases in the atmosphere and hence global warming.

Which of the following gasses contribute to greenhouse effect?

  1. $CO _2$

  2. $CH _4$

  3. $CFC$s

  4. All of the above

Show answer
Correct Option: D
Explanation:

Green house causes the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are carbon dioxide, methane, nitrous oxide and ozone.


Chlorofluorocarbons (CFCs) are also a greenhouse gases.

So, the correct option is $D$

Argon is a greenhouse gas. 

chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Argon is not a greenhouse gas because it is mostly transparent to the wavelengths of light that is responsible for trapping heat.

Which of the following is a greenhouse gas?

chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

  1. Nitrogen

  2. Oxygen

  3. Ozone

  4. Helium

Show answer
Correct Option: C
Explanation:

A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, and ozone. 

_________ is a gas in an atmosphere that absorbs and emits radiation within the thermal infra-red range.

chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

  1. Global gas

  2. Greenhouse gas

  3. Green gas

  4. Noble gas

Show answer
Correct Option: B
Explanation:

A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. 

Black carbon, a potential global warming gas causes__________.

chemistry air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

  1. human morbidity

  2. premature mortality

  3. both a and b

  4. asthma

Show answer
Correct Option: C
Explanation:

Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality.
