What are greenhouse gases?
Some Long wave is lost to space
S U N
Some Long wave is lost to space
Reflected by Earths surface to space.
Converted into heat causing the emission of
longwave radiation
Solar Energy Absorbed at the surface
Surface gains more heat and longwave radiation is
emitted again
Surface gains more heat and longwave radiation is
emitted again

These are just a few causes of greenhouse gases!
