One of the characteristics of contour is that the variation of the vertical distance between any of the two contour lines are usually assumed to be uniform. The other characteristic is that all the points on a contour line are of the same elevation.
it is a contour line of elevation Control index contour, or just index contour
- Contour lines never cross. All lines on a contour line represent one elevation.- The spacing of contour lines depends on slope characteristics. Contour lines that are close together show a steep slope. Contour lines that are far apart show a gentle slope.- Contour lines that cross a valley or a stream are V shaped. The C points toward the area of the highest elevation. If a stream or river flows through the valley, the V points upstream.-The tops of the hills, mountains, and depressions are shown by closed circles. Depressions are marked with short, straight lines inside the circle that point down slope to the depression.

Topography refers to the study or detailed description of the surface features of a region, including its elevation, shape, and terrain characteristics. It is often depicted on maps using contour lines to show changes in elevation and land features.
the contour interval is the difference in elevation between contour lines that are next to each other
A complicated contour is heavier.
It makes it easier to count the number of contour lines.
index contour lines have numbers contour lines dont

It helps to prevent soil erosion, allows for water to be absorbed by the soil and can even be used strategically to divert water to drier locations on farm land.
