Answerer Answer :-

Imaginary lines joining places which have the same height above the sea level are called contours.

A contour line of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f parallel to the x, y plane.
