The Earth loses absorbed heat primarily by radiating long-wavelength infrared energy upward into space and through atmospheric convection and evaporation. This radiative cooling prevents thermal buildup and maintains stable global temperatures.

Chapter 13 Earth as a System: Energy, Matter and Life Question Answer
The Earth’s surface sheds absorbed solar energy mainly by emitting longwave infrared radiation back towards the upper atmosphere and outer space, complemented by evaporative latent heat transfer and convective air currents. This continuous outward radiation is vital because it establishes a balanced global thermal equilibrium, preventing catastrophic planetary overheating and sustaining habitable climatic zones across the Earth.
