Why is carbon dioxide called a greenhouse gas?
Answer and explanation
Correct answer: It absorbs infrared heat emitted by Earth and helps retain it in the atmosphere
The governing concept is the greenhouse effect. Earth’s surface absorbs sunlight and emits energy mainly as infrared radiation. Carbon dioxide absorbs some of this outgoing infrared radiation and re-emits energy in different directions, including back toward the surface, so heat is retained more effectively in the lower atmosphere. It does not destroy all oxygen, consist of dust, or occur in the greatest amount; nitrogen is most abundant.
