-
Temperature:
-
A measure of the quantity of heat energy in a substance, such as air, a star, or even the human body. Because heat energy corresponds to motions and vibrations of molecules, hotness provides in sequence about the amount of molecular motion going on in a substance.
-
Terrestrial Planets:
-
The four planets of the inner solar system (Mercury, Venus, Earth, and Mars) are known terrestrial planets since they are made up mostly of rock.
