Answer 2

Answer:

-In the absence of an atmosphere, Earth’s surface temperature would be about –18°C, or 0°F, which is way too cold for life.

-Earth is habitable because of the ‘greenhouse effect’ -a slightly inaccurate term for the heating of Earth’s atmosphere due to the presence of greenhouse gases such as water vapor, carbon dioxide (CO2), methanes (CH4) and nitrous oxide (N2)).

-Greenhouse gases have just the right molecular structure to absorb infrared radiation that the Earth emits. It re-emits most of that infrared energy in all directions, warming the atmosphere to its comfortable average temperature of 15°C (60°F). So the greenhouse effect is a good thing.
