Isolines are lines on a map that connect points of equal value, such as temperature, air pressure, elevation, latitude, or longitude. There are five major types of isolines: isotherms, isobars, contour lines, parallels, and meridians. Isolines must never cross each other, begin and end at the edge of the map or form closed circles, and usually appear as wavy parallel lines.

There are 5 major types of Isolines :
1. Isotherms (lines that connect points of equal temperature).
2. Isobars (lines that connect points of equal air pressure).
3. Contour Lines (lines that connect points of equal elevation).
4. Parallels (lines that connect points of equal latitude).
5. Meridians (lines that connect points of equal longitude).
Isoline Rules:
1. Isolines NEVER cross.
2. Isolines begin and end at the edge of a page or form
a circle.
3. Isolines usually form wavy parallel lines.
