A contour line (also known as a level curve) for a given surface is the curve of intersection of the surface with a horizontal plane, z = c. A representative collection of contour lines, projected onto the xy -plane, is a contour map or contour plot of the surface.
Use a different symbol or color for the data points from “Point A” to the rim and from “Point B” to the rim. Label the x axis with total distance (km) (Column C) Label the y axis with elevation (m) (Column A) Connect the data points for each set of data. Write a key for the graph.

How are topographic maps able to show three-dimensional objects like hills on a two-dimensional object like a piece of paper? They do it by using contour lines. Contour Lines are curves that connect points of equal elevation. Each contour line on a map has a number that represents the elevation of the line (usually the height above sea level).

Level curves are the equivalent of contours on a topographical map. In such a map the terrain is shown by drawing curves through all points which have the same height above sea level. The numbers on the curves in the map shown below are the heights above sea level in metres.

A topographical map contains curved lines called contour lines. Each contour line corresponds to the points on the map that have equal elevation (Figure 1). A level curve of a function of two variables [latex]f\,(x,\ y)[/latex] is completely analogous to a counter line on a topographical map.
