Multiple choice zoology human influences on the environment carbon cycle ozone layer depletion and causes depletion of ozone layer

Increase in carbon dioxide in atmosphere is harmful because it

  1. traps heat

  2. causes respiratory disorders

  3. forms smog

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

Carbon dioxide is one of the most abundant and major greenhouse gas which entraps the heat and causes the rise in temperature of the earth surface hence is greatly responsible for global warming also.

so the correct answer is 'traps heat'.

Multiple Choice Questions
Which one is correct percentage of green house gases

  1. Methane - $20\%$, $N _2O $- $18\%$
  2. CFCs -$14\%$, Methane - $20\%$
  3. $CO _2$ - $40\%$, CFCs -$30\%$
  4. $N _2O$ - $6\%. $ $CO _2$ - $86\%$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Relative concentration of various greenhouse gases in the atmosphere is as: CO$ _2$ (60%), CH$ _4$ (20%), CFCs (14%) and N$ _2$O (6%).

So, the correct answer is CFCs-14%, Methane 20%.

Identify the wrong statement/ statement from the following.
(1) ${ CO } _{ 2 }$ is released into the atmosphere through volcanic activity
(2)${ CO } _{ 2 }$ is released into the atmosphere through process of photosynthesis
(3)${ CO } _{ 2 }$ is released into the atmosphere through process of respiration
(4)${ CO } _{ 2 }$ is released into the atmosphere through process of forest fires


  1. 1 and 3

  2. only 2

  3. only 4

  4. 2 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Oxygen is released in the atmosphere through the process of photosynthesis. Carbon dioxide is released by different human activities like the burning of fossil fuels,  deforestation, burning of petrol etc.

So, the correct option is 'Only 2'.

The legally binding international agreement to reduce Greenhouse gases by 5% 2012 is ___________

  1. Vienna convention

  2. Montreal Protocol

  3. Kyoto Protocol

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

The Kyoto Protocol was an international treaty that extended the 1992 United Nations Framework Convention on Climate Change, committing state parties to reduce greenhouse gas emissions based on the scientific consensus that global warming is occurring.

Which of the following gases are mainly responsible for the atmospheric greenhouse effect in the earth's atmosphere?

  1. Oxygen and nitrogen

  2. Nitrogen and carbon dioxide

  3. Ozone and oxygen

  4. Water vapor and carbon dioxide
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water vapor and carbon dioxide are the most significant contributors to the greenhouse effect in the Earth's atmosphere, with water vapor being the most abundant and CO2 being the most significant anthropogenic contributor.

The gas responsible for the greenhouse effect on Venus is:

  1. Carbon dioxide $(CO _{2})$
  2. Oxygen $(O _{2})$
  3. Ozone $(O _{3})$
  4. Nitrogen $(N _{2})$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Venus has a thick atmosphere composed primarily of carbon dioxide, which creates an extreme greenhouse effect, resulting in surface temperatures hot enough to melt lead.

Green House effect is caused by

  1. Increase in $CO _{2}$
  2. Increase in $O _{2}$
  3. Decrease in $O _{2}$
  4. Decrease in $CO _{2}$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The greenhouse effect is primarily driven by the accumulation of greenhouse gases in the atmosphere, which trap heat. Carbon dioxide (CO2) is the most significant anthropogenic greenhouse gas contributing to this effect.

Multiple choice zoology human influences on the environment carbon cycle ozone layer depletion and causes depletion of ozone layer

Which of the following green house gases trap more heat?

  1. Methane

  2. Nitrous oxide

  3. Carbon dioxide

  4. Trifluoro methyl sulphurpentafluoride
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Trifluoromethyl sulfur pentafluoride (SF5CF3) is an extremely potent greenhouse gas with a global warming potential thousands of times higher than carbon dioxide. While CO2 is the most abundant, this specific compound is significantly more effective at trapping heat per molecule.

Multiple choice zoology human influences on the environment carbon cycle ozone layer depletion and causes depletion of ozone layer

What would be average temperature of earth without greenhouse gases?

  1. $90^{o}C$
  2. $70^{o}C$
  3. $10^{o}C$
  4. $18^{c}ircC$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Without the natural greenhouse effect, Earth's average surface temperature would be approximately -18 degrees Celsius. The current average temperature is about 15 degrees Celsius due to the natural greenhouse effect.
