How heat is transferred by convection

WebEnergy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. NOAA NWS. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. WebHeat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles.
