| Electromagnetic waves | aka: radiation |
| Electromagnetic spectrum | all of the various wavelength of energy emitted by the Sun make this up |
| Nuclear fusion | the power source for our Sun |
| 3 things the Earth's atmosphere does to incoming radiation are | absorbed, reflected or transmitted |
| Radiation | energy waves traveling through empty space |
| Conduction | heat transfer by contact of molecules or matter |
| Convection | heat transfer where the heat causes a material to move, more evenly distributing the heat |
| cooking bacon in a pan | example of conduction |
| water boiling | example of convection |
| getting a sun tan | example of radiation |
