Lines drawn on maps connecting points of equal value are called what?

Explanation:
Isopleths are lines drawn on a map that connect locations where a given quantity is the same. They reveal how that variable changes across space by tracing where its value remains constant. For example, isotherms map temperature, isobars map atmospheric pressure, and isohyets map rainfall. This differs from contour lines, which map elevation, and from a spot height, which is a single elevation value at one point. Symbols and grids are different map elements altogether. So, the lines linking equal values are isopleths.
