Greenhouse gases heat the lower atmosphere mainly because they absorb

  1. AX-rays coming from the Sun
  2. Binfrared radiation emitted by the Earth's surface
  3. Cultraviolet radiation coming from space
  4. Dradio waves reflected from the ionosphere

The Earth re-radiates absorbed solar energy as infrared. Greenhouse gases absorb part of this infrared and re-emit it, which warms the lower atmosphere.
