WebHeat flows from centre of Earth to surface via:- conduction - thermal vibrations: every atom is physically bonded to its neighbours in some way. If heat energy is supplied to one part of a solid, the atoms vibrate faster. As they vibrate more, the bonds between atoms are shaken more. This passes vibrations on to the next atom, and so on: WebThe rate of heat flow is the amount of heat that is transferred per unit of time in some material, usually measured in watt ( joules per second).
