Greenhouse effect
How does Greenhouse effect work?
Most shortwave radiation is absorbed by the Earth's surface which then heats up as a result
The warmed substance of the Earth emits a longwave radiation to the atmosphere
Some shortwave radiation is reflected by the Earth and the atmosphere
Greenhouse gases absorb longwave radiation, warming the atmosphere
Incoming shortwave radiation from the sun passes through the atmosphere
