2 Convection Currents Heat is transferred through: 1.Radiation 2.Conduction 3.Convection

3 Convection Currents Radiation Transfer of energy by electromagnetic waves

4 Convection Currents Conduction Heat transfer by direct contact of particles of matter

5 Convection Currents Convection Heat transfer by movement of a heated fluid.

6 Convection Currents Convection in the Earths Mantle Heat from the earth’s core and from the mantle itself causes the convection currents in the mantle
