Ans. The greenhouse effect is the manner in which "greenhouse gases" trap heat near the Earth's surface. Such heat-trapping gases can be thought of as a blanket wrapped around the Earth that makes it more toasted than it would be without them. Carbon dioxide, nitrogen, and nitrous oxides are among the greenhouse gases.

Carbon dioxide, nitrogen, and nitrous oxides are among the greenhouse gases. In the last century or so, however, humans have messed with the planet's energy balance, largely by burning fossil fuels that emit extra carbon dioxide into the air.
