Heat Energy

It plays a vital

role in our

planet.

Sources of heat

energy are

identified as

Primordial Heat

and Radiogenic

Heat

Sources of Heat and Heat Transfer 3 process of Heat Transfer:

1. Conduction
   2. Convection
      3. Radiation

3 process of Heat Transfer: Sources of Heat and Heat Transfer occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.

Conductio

n

the process by which heat energy is transmitted through collisions between neighboring atoms or molecules

3 process of Heat Transfer: Sources of Heat and Heat Transfer Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle which results to movement of tectonic plates the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.
