| Atmosphere | The layer of gases that surrounds the Earth. |
| Ozone | A form of oxygen that has three oxygen atoms instead of two. |
| Water Vapor | Water in a form of a gas. |
| Density | The amount of mass of a substance in a given value (D=Mass/Volume) |
| Pressure | The force exerted on a surface divided by the total area over which the force is exerted. |
| Air Pressure | The pressure caused by the weight of a column of air pushing down on an area. |
| Barometer | An instrument used to measure air pressure. |
| Mercury Barometer | An instrument used to measure air pressure;consists of a glass tube partially filled with mercury, with its open end resting in a dish of mercury. |
| Aneroid Barometer | An instrument that measures air pressure without using a liquid. |
| Altitude | Elevation above sea level. |
| Troposphere | The lowest layer of the Earth's atmosphere, where weather occurs. |
| Stratosphere | The second-lowest layer of the Earth's atmosphere. The ozone layer can be found here. |
| Mesosphere | The layer of the Earth's atmosphere immediately above the stratosphere; the layer in which the meteroids burn up. |
| Thermosphere | The outermost layer of Earth's atmosphere;the hottest layer. |
| Ionosphere | The lower part of the thermesphere, where electrically charged particles called ions are found. |
| Exosphere | The outer layer of the thermosphere, extending into space. |
| Conduction | The direct transfer of thermal energy from one substance to another substance that it is touching. |
| Convection | The transfer of thermal energy by the movement of a fluid (liquid or gas). |
| Radiation | The direct transfer of energy by electronic waves. |
