Which gases contribute to the greenhouse effect? a. nitrogen and helium b. carbon dioxide and methane c. carbon dioxide and helium d. nitrogen and methane

Correct B). Carbon dioxide and methane

Greenhouse gases are those gas which traps the heat of the atmosphere, it absorbs the heat energy and allows the less heat to escape back to space.

The greenhouse gases found naturally in the earth's atmosphere are carbon dioxide, water vapor, methane, and nitrous oxide, while the man made greenhouse gases are Chlorofluorocarbons, hydrofluorocarbons etc.

The concentration of these both the greenhouse gases are increasing rapidly due to industrialization and overuse of fossil fuel such as coal, petroleum etc which ultimately leads to global warming.
