Gradient

• An area with a measurable value of a particular quality, like temperature, at various points

• Line of equal field values or line of equal pressure values

• The rate of change in a field value (also called the average slope); calculated by dividing the change in field value by the change in horizontal distance

Lines of equal field values or lines of equal pressure values

Lines of equal temperature values

• Isotops

• contour lines

• Isoterms

• gradient lines
