Final answer:
The greenhouse effect is the storage of heat in the lower layer of the atmosphere produced by certain heat absorbing gases. These gases trap some of the infrared radiation that escapes from the Earth's surface, which keeps the lower layers warmer than they would otherwise be.
Correct answer D
Step-by-step explanation:
The greenhouse effect is the storage of heat in the lower layer of the atmosphere produced by certain heat absorbing gases.
These gases, such as carbon dioxide, trap some of the infrared radiation that escapes from the Earth's surface.
This trapping of energy in the Earth's atmosphere keeps the lower layers warmer than they would otherwise be, resulting in the natural greenhouse effect.
Correct answer D
