Multiple choice biology air and water pollution control environmental impact: global warming green house effect geobiochemical cycle

What causes the global warming?

  1. Burning of fossil fuels

  2. Deforestation

  3. Industrialization

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
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

Reveal answer Fill a bubble to check yourself
D Correct answer
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 $D$

Which of the following is a greenhouse gas?

  1. Nitrogen

  2. Oxygen

  3. Ozone

  4. Helium

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

  1. Global gas

  2. Greenhouse gas

  3. Green gas

  4. Noble gas

Reveal answer Fill a bubble to check yourself
B Correct answer
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__________.

  1. human morbidity

  2. premature mortality

  3. both a and b

  4. asthma

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

The greenhouse effect is useful because:

  1. it reduces water pollution

  2. it increases normal temperature of earth

  3. keeps the temperatures on our planet mild and suitable for living things

  4. reduces greenhouse gases

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

The greenhouse effect is useful because trapping some energy keeps the temperatures on our planet mild and suitable for living things. Without its atmosphere and the greenhouse effect, the average temperature at the surface of the Earth would have been very low.

Greenhouse gases cause:

  1. ocean acidification

  2. ozone depletion

  3. smog pollution

  4. all of above

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

Increases in the different greenhouse gases have other effects apart from global warming, including ocean acidification (by acid rain), smog pollution (contaminated particles in air) and ozone depletion as well as changes to plant growth and nutrition levels.

Which of the following is next to carbon dioxide for its contribution to global warming?

  1. $CFC$s
  2. $CO$
  3. Black carbon

  4. Ozone

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

Black carbon is second only to carbon dioxide for its contribution to global warming. Chemically, black carbon or BC is a component of fine particulate matter. 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.

Which of the following is a factor that affect the degree to which any greenhouse gas will influence global warming?

  1. Its abundance in the atmosphere.

  2. How long it stays in the atmosphere.

  3. Its global-warming potential.

  4. All of above.

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

By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. Three factors affect the degree to which any greenhouse gas will influence global warming: its abundance in the atmosphere, how long it stays in the atmosphere and Its global-warming potential.
