Ozone: A molecule of oxygen containing three oxygen atoms

Troposphere: The lowermost layer of the atmosphere; It is generally characterized by a decrease in temperature with height

Stratosphere: The layer of the atmosphere immediately above the troposphere, characterized by increasing temperatures with height, due to the concentration of ozone

Mesosphere: The layer of the atmosphere immediately above the stratosphere and characterized by decreasing temperatures with height

Thermosphere: The region of the atmosphere immediately above the mesosphere and characterized by increasing temperatures due to absorption of very short-wave solar energy by oxygen

Heat: Thermal energy transferred from one object to another

Radiation: The transfer of energy (heat) through space by electromagnetic waves
