The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
A physical map shows mountains, hills, and plains through shading or contour lines. This type of map uses color gradients or elevation contour lines to depict the topography of an area.
Contour lines show levels of elevation, where there are hills and valleys on a map
Contour lines that touch or overlap on a topographic map indicate a
The heaviest contour lines on a topographic map indicate the highest elevation on the map. These lines represent the peaks of mountains, hills, or other elevated land features.

Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
Contour lines that touch or overlap on a topographic map indicate a
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
The closer the contour lines, the steeper is the slope.
