Term | Definition |

Ozone | a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. |
Troposphere | the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere. |
Stratosphere | the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere). |
Mesosphere | the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude. |
Thermosphere | the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height |
Exosphere | the outermost region of a planet's atmosphere. |
Radiation | through space |
Conduction | by contact |
Convection | flow of heated substance |
Temperature | the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch. |
Heat | transfer of energy |
Dew Point | the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form. |
Humidity | the state or quality of being humid. |
Relative Humidity | the amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature. |
Density | degree of consistency measured by the quantity of mass per unit volume. |
Air Pressure | the pressure within the atmosphere of Earth. |
