contour line
Map's height marker
A contour line connects points of equal elevation on a map, creating a visual representation of terrain.
Where contour lines cluster tightly together, the slope is steep; where they spread apart, the land is relatively flat.
The contour lines on the topographic map showed a sharp ridge running north-south.
In art, contour lines trace the outline or shape of a figure.
