Which statement about the greenhouse effect and greenhouse gases is correct?
Greenhouse gases absorb incoming short-wavelength solar radiation and reflect it directly back to space.
The greenhouse effect occurs because greenhouse gases absorb outgoing infrared radiation and re-emit it in all directions, including back towards Earth.
Decreasing the concentration of greenhouse gases in the atmosphere would cause the global average temperature to rise.
Diatomic nitrogen (N2\text{N}_2N2) and oxygen (O2\text{O}_2O2) are the primary greenhouse gases in Earth's atmosphere.
