Which of the following gases is NOT a part of Greenhouse gases?

Which of the following gases is NOT a part of Greenhouse gases? Correct Answer Oxygen

The correct answer is Oxygen.

Concept:

Greenhouse gases: The gases which allow solar radiation to pass through them but retain and particularly reflect back radiation of longer wavelength are called greenhouse gases, e.g., Carbon dioxide, methane, water vapour, nitrous oxide, chlorofluorocarbons and ozone etc.

Explanation:

Oxygen is not a greenhouse gas.

Carbon dioxide (CO2):

  • Carbon dioxide is the main abundant (60 per cent) among greenhouse gases.
  • Carbon dioxide molecules also trap heat as they are transparent to sunlight but not to heat radiation.
    If the amount of carbon dioxide crosses the delicate proportion of 0.03 per cent, the natural greenhouse balance may get disturbed. Carbon dioxide is a major contributor to global warming.

Methane (CH4):

  • Methane is produced naturally when vegetation is burnt, digested or rotted in the absence of oxygen.
  • Large amounts of methane are released in paddy fields, coal mines, rotting garbage dumps and by fossil fuels.

Nitrous oxide (NO2):

  • Nitrous oxide occurs naturally in the environment.
  • In recent years, their quantities have increased significantly due to the use of chemical fertilizers and the burning of fossil fuels.

In the question below is given a statement followed by two courses of action numbered I and II. You have to assume everything in the statement to be true and on the basis of the information given in the statement, decide which of the suggested course of action logically follow(s) for pursuing. Statement: Uncontrolled release of greenhouse gases, have resulted in the degradation of the ozone layer and global warming.

Rearrange the given 5 sentences A, B, C, D and E in proper sequence to form a meaningful paragraph and mark the correct sequence from the given options as your answer. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.
With regard to greenhouse gases, which of the following statement(s) is true? 1. The primary greenhouse gases of concern today are Carbon dioxide and chloro-fluorocarbons, which absorb terrestrial radiation when it is present in the upper troposphere. 2. Ozone which absorbs ultraviolet radiation in the stratosphere is very effective in absorbing terrestrial radiation when it is present in the upper troposphere.

The question below consists of a set of labelled sentences in which first and the last sentence is given. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. S1- Climatic changes have become more prominent now because of global warming which is a global concern. P- Such gases never let sun rays to go back to the atmosphere, however, trap heat from them.  Q- The release of various greenhouse gases in the atmosphere by many natural means and human activities causes an increase in atmospheric temperature because such gases have a capability to absorb all the heat of environment from the sun, burning coal, etc. R- Both are hot issues of the current time and it is the time to analyse causes and prevention methods to prevent global warming.  S- Fossil fuels burning release more carbon dioxide which is increasing day by day because of deforestation.  S6- Plants are the main source to utilize carbon dioxide as a food, however, we are disturbing the natural cycle by cutting more plants.
