1 What processes heat the atmosphere? What is radiation?What is conduction?What is convection?
2 Radiation Conduction Convection 1. What processes heat the atmosphere?RadiationConductionConvection
3 2. What is Radiation? Transfer of heat energy as waves - Some radiation energy is reflected and some is absorbed
4 3. What is Conduction? Transfer of heat energy by direct contact - air molecules touch a warm surface- heat moves from warm to cold
5 4. What is Convection?Transfer of heat energy by the circulation of a gas or liquidwarm air rises because it is less dense- cold air sinks because it is more dense*Moves the most heat energy in the atmosphere.
