| ozone layer | Layer of the stratosphere that protects the Earth from UV radiation. |
| albedo | Amount of light that is reflected back by the surface. |
| exosphere | Upper part of the thermosphere that is the beginning of space; is where satellites orbit. |
| troposphere | Lower most layer of the atmosphere; it is where we live and where the weather takes place. |
| radiation | Transfer of energy (heat) through space by electromagnetic waves. |
| conduction | Transfer of heat through matter by direct contact. |
| aurora | Bursts of light created by the collisions of solar particles with gases in the magnetosphere. |
| scattering | The redirecting of light by small particles and gas molecules in the atmosphere. |
| thermosphere | Region of the atmosphere right above the mesosphere; it is the warmest layer. |
| magnetosphere | Highly magnetized region around Earth that extends beyond the atmosphere. |
| stratosphere | The second layer of the atmosphere; it contains the ozone layer and is where jets fly. |
| convection | Transfer of heat by the movement of a liquid or gas. |
| reflection | Light bounces back from an object at the same angle at which it encounters a surface and with the same intensity. |
| mesosphere | Third layer of Earth’s atmosphere; it is the coldest layer and where meteoroids burn up. |
| ionosphere | Lower part of the thermosphere that contains many electrically charged particles important for communication. |
