What is the greenhouse effect? Name the atmospheric gases which lead to it and what is its impact on the global climate?

(N/A) The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat from the sun,preventing it from escaping back into space and thereby warming the planet.
$(b)$ The primary greenhouse gases responsible for this effect include Carbon dioxide $(CO_{2})$,Methane $(CH_{4})$,Nitrous oxide $(N_{2}O)$,and Chlorofluorocarbons $(CFCs)$.
$(c)$ The impact of the greenhouse effect on the global climate is known as global warming,which leads to the melting of polar ice caps,rising sea levels,and significant changes in weather patterns worldwide.
