Heat Transfer in the Atmosphere
Energy moves through the atmosphere in three ways: radiation, conduction, and convection.
Radiation occurs when energy travels as waves, like the Sun’s rays, moving through space to reach Earth. This energy heats Earth’s surface, and some radiates back into the air as heat.
Conduction happens when fast-moving, warm molecules touch slower, cooler ones and transfer heat. It mostly occurs near the ground, where the air touches the warm surface of the Earth.
Convection moves heat through currents in gases or liquids, such as air or water. The air near the ground, warmed by radiation from the Earth, rises because it’s less dense, while cooler air sinks because it’s denser.
This rising and sinking of air forms convection currents that spread heat through the atmosphere. Convection can also be observed when a hot air balloon rises up into the air.
Radiation starts the process of heat transfer, conduction spreads the heat near the ground, and convection carries it through the sky. These three methods work together to move energy and keep our atmosphere in motion.
