Radiation is the transfer of heat energy through electromagnetic waves. Unlike conduction and convection, radiation does not require a medium (like a gas, liquid, or solid) to travel through. This is why radiation can occur in the vacuum of space, where there are no particles to facilitate the transfer of heat energy. When the Sun's energy reaches Earth, it is absorbed by the Earth's surface, heating it up. This heat is then transferred to the surrounding air by conduction and to the rest of the atmosphere by convection. Some of the heat is also radiated back into space. |
