Greenhouse Gases and Atmosphere Questions

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

Which one of the following is not responsible for the greenhouse effect?

  1. Carbon dioxide

  2. Methane

  3. Argon

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

Argon :-


The major greenhouse gases (GHG’s) solely responsible for greenhouse effect are Carbon dioxide, Ozone, Methane and Water vapor. Although these gases comprise 1% of our atmosphere, they act like a thick warm blanket outside that surrounds this planet and regulate climate control. Greenhouse effect is not bad. In fact, it is needed for all of us to survive on planet Earth. In short, the greenhouse effect is nothing but a naturally occurring process designed by nature that aids in heating earth’s surface and helps to maintain ecological balance.

Now, while some of that heat dissipates into space, some of it burns along the atmosphere, and some of it penetrates the atmosphere and finds its way into the lower atmosphere and the planet’s surface. This in turn raises the average temperature of the Earth. Therefore, the increase in the Earth’s surface temperature due to increase in the number of greenhouse gases leads to global warming.

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

The principle green house gases are ____________.

  1. Methane

  2. Carbon dioxide

  3. Chlorofluorocarbon

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

Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are:

  • Water vapor
  • Carbon dioxide
  • Methane
  • Ozone
  • Nitrous oxide
  • Chlorofluorocarbons

Multiple choice

What is the main constituent of coal gas?

  1. Oxygen

  2. Water

  3. Nitrogen

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

Coal gas is a flammable gaseous fuel made from coal. Its primary components are hydrogen, methane, and carbon monoxide, with methane being a significant constituent.

Multiple choice zoology bio-geo chemical cycles in nature nutrient cycles- flow of substances carbon cycle biogeochemical cycles - gaseous

Proportion of CO consumption consists of basic components:

  1. The leaf boundary layer

  2. The stomata

  3. Radiation exchange

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

The consumption of carbon dioxide by plants is influenced by various factors including the leaf boundary layer, stomatal conductance, and the energy balance (radiation exchange).

Multiple choice evs - i for a pollution free nature ways to prevent air pollution ways to reduce air pollution reducing air pollution

Which of the among is a major greenhouse gas implicated in global warming?

  1. $\displaystyle { CH } _{ 4 }$
  2. $\displaystyle { CO } _{ 2 }$
  3. $\displaystyle { NH } _{ 3 }$
  4. $\displaystyle { N } _{ 2 }$
  5. $\displaystyle { O } _{ 2 }$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Option A is the correct answer.

Methane absorbs heat from the sun very effectively and warms the atmosphere, and hence it is a major greenhouse gas

Multiple choice zoology bioenergy biogas environmental use of microorganism microbes in waste treatment and biogas

What does gobar gas produced from animal and plant waste contain?

  1. Ethane

  2. Methane

  3. Propane

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

Biogas is also commonly known as gobar gas. The biogas is produced due to anaerobic decomposition of the organic waste matter from the plants and animals with the help of microorganisms. The composition of biogas is methane and carbon dioxide. There are traces of hydrogen, nitrogen, hydrogen sulphide and carbon monoxide. The major component is of methane which accounts for 50-70%. Methane forms the clear and non-polluting gas and commonly used as a fuel.

Thus, the correct answer is option B.  

Multiple choice zoology bioenergy biogas environmental use of microorganism microbes in waste treatment and biogas

Which one of the following is a major constituent of Biogas?

  1. Carbon dioxide

  2. Methane

  3. Hydrogen

  4. Nitrogen dioxide
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Biogas is a mixture of mostly methane and carbon dioxide with trace amounts of other gases and is considered as a valuable renewable energy source.
  • Methane comprises of 45-70% of biogas and thus biogas is inflammable. It produces a deep blue flame and can be used as an energy source.
Multiple choice chemistry group 17 group 17 - physical properties physical properties of group 17 elements group 17 elements: the halogen family

Which of the following is not a green house gas?

  1. $CO _2$
  2. $CH _4$
  3. $O _3$
  4. $N _2X$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Greenhouse gases are gases in an atmosphere that absorbs and releases radiation This process is the cause of the greenhouse effect. The main greenhouse gases in Earth's atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, and ozone. So $N _2X$ is not greenhouse gas.

Hence option $D$ is correct.

Multiple choice zoology environmental factors environmental factors and their measurements climate factors marine life

Greenhouse gases are

  1. CO$ _{2}$
  2. CH$ _{4}$

  3. CFC

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

Green house gases (e.g. CO$ _{2}$, CH$ _{2}$, CFCs etc.) are increasing in the atmosphere due to human and natural activities. These gases trap the heat(infra-red radiation) reflected by the earth. This heats up the atmosphere(leads to an increase in earth's temperature). This phenomenon is called global warming which occurs due to green house effect.

Multiple choice zoology ecosystem : structure and function biogeochemical cycles - sedimentary biogeochemical cycle nitrogen and phosphorus cycles

Which is not a gaseous biogeochemical cycle?

  1. Sulphur

  2. Phosphorus

  3. Nitrogen

  4. Carbon
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

Biochemical cycle is also called as biogeochemical cycle or nutrient cycle. Biochemical cycle with gaseous phase includes various cycles like carbon cycle, nitrogen cycle, oxygen cycle. The nitrogen, carbon and oxygen are found in the gaseous form in the atmosphere. Calcium cycle, sodium cycle, phosphorous cycle, iron cycle, magnesium cycle, sulphur cycle are sedimentary cycles.

Thus, the correct answer is 'Sulphur and Phosphorus.'
