| Conduction | Heat transfer by direct contact of particles of matter |
| Convection | Heat transfer by the movement of a heated liquid |
| Heat Transfer | The movement of heat from a warmer object to a cooler object |
| Radiation | The transfer of energy through empty space |
| Convection Current | The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another |
| Density | The amount of mass in a given space, mass per unit volume |
| What causes convection currents? | Differences of temperature and density within a fluid |
| Three ways heat can be transferred | radiation, conduction, convection |
