Question
Hint:
The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
- Many greenhouse gases in the atmosphere prevent the heat from escaping into space and trap lot of heat next to the Earth, triggering is correct
