False

Contour lines on a map are lines of constant elevation above sea level. The "contour interval" is the vertical distance represented by adjacent contour lines.

The horizontal distance between contour lines on a map depends on the slope of the terrain. Lines are closer together when th slope is steep. The amount of distance on the ground that a distance on the map represents is determined by the scale of the map, not the contour interval.
