Question

Discuss briefly Greenhouse gases.

Answer 1

This increase in heat is called the greenhouse effect. Common examples of greenhouse gases, listed in order of abundance, include: water vapor, carbon dioxide, methane, nitrous oxide, ozone, and any fluorocarbons.


One of them is through human activities. The main human sources of greenhouse gas emissions are: fossil fuel use, deforestation, intensive livestock farming, use of synthetic fertilizers and industrial processes. The other is through natural processes like animal and plant respiration.

Answer 2

Answer:

Greenhouse gases

This effect refers to the global increase in the average temperature of the Earth as a result of greenhouse gases. These gases are methane, carbon dioxide and water vapor. When solar rays are incident on Earth, some of these are absorbed which are released back into the atmosphere. The greenhouse gases present in the atmosphere trap these radiations which helps in keeping Earth warm, hence suitable for humans to survive. Therefore, increase in the level of greenhouse gases can lead to an increase in the temperature of Earth overall resulting in Global warming.
