उत्तर

The Earth’s surface re-radiates absorbed solar energy as infrared radiation. Some of this heat escapes to space, while greenhouse gases absorb and re-emit much of it, keeping the planet warm. This process maintains Earth's energy balance and a livable average temperature; without it, Earth would be freezing.
