The greenhouse gases as per their increasing order of effectiveness are

The greenhouse gases as per their increasing order of effectiveness are Correct Answer CO<sub>2</sub>, CH<sub>4</sub>, N<sub>2</sub>O and CFC

  • The effectiveness of greenhouse gases can be estimated by using a factor Global Warming Potential (GWP); It is developed to allow comparisons of the global warming impacts of different gases
  • It is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2)
  • Methane (CH4) is estimated to have a GWP of 28–36 over 100 years
  • Nitrous Oxide (N2O) has a GWP 265–298 times that of CO2 for a 100-year timescale
  • Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO2 (The GWPs for these gases can be in the thousands or tens of thousands) 

 

The greenhouse gases as per their increasing order of effectiveness are:

CO2, CH4, N2O, and CFC

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.

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.
