Answer:
the trapping of heat energy in the troposphere by certain gaseous molecules.
Explanation:
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
Hence, the term greenhouse effect describes the trapping of heat energy in the troposphere by certain gaseous molecules such as water vapor.
Additionally, troposphere is the lowest and most dense layer of the earth's atmosphere that causes a significant change in weather and charactized by temperature decrease.
