Question

Explain how the greenhouse effect causes global warming.

Answer 1

Global warming is the gradual increase in the average temperature of the earth’s atmosphere. It is caused by the increased concentration of greenhouse gases in the atmosphere due to various human activities like the burning of fossil fuels, large-scale deforestation, etc.

The greenhouse gases like carbon dioxide, methane, and others trap the heat coming from the sun in the atmosphere and prevent it from escaping. This phenomenon is called the greenhouse effect. It makes the surface of the earth warm and makes the survival of living beings possible. However, due to the increased concentration of greenhouse gases, the temperature of the earth has increased considerably leading to global warming.
