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

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.

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

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.

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.

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.

Earth's surface temperature can be altered, by changing concentration of

  1. Heat

  2. Greenhouse Gases

  3. Air pollutants

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

Greenhouse gases regulate the Earth's temperature by absorbing and re-emitting infrared radiation. Changing their concentration directly alters the energy balance of the planet.

Which among the following is the most correct statement in context with Carbon footprint?

  1. It is a measure of Green house gas emissions by a product

  2. It is a unit under the Kyoto Protocol representing a reduction of greenhouse gases under the Joint Implementation mechanism

  3. It is a administrative approach used to control pollution by providing economic incentives for achieving reductions in the emissions of pollution

  4. All of above are correct
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A carbon footprint is defined as the total amount of greenhouse gases, including carbon dioxide and methane, generated by our actions or by a specific product.
