A contour line is simply a line drawn on a map to show land the same elevation (height above sea level). The British Ordinance Survey maps, for example, typically use brown lines to shown land at 50 metre intervals. If you walked along a contour line, you would be walking on entirely flat ground, neither rising or falling. Where the contour lines on a map are close together, it means that the land rises or falls sharply, as on the side of hills, etc.

A contour line in art is an outline of a subject with no shading.
An Index Contour
The first contour line was created by Charles Hutton in 1771. He used contour lines to map a coal mine.
The size in the change of elevation from one contour line to another is called the contour interval. It represents the vertical distance between each contour line on a topographic map. The contour interval helps in understanding the slope and elevation changes of the terrain being represented.
No. Contour lines connect points of the same elevation
it is a contour line of elevation Control index contour, or just index contour

A contour line is a line defining elevation on a map.
To find the contour interval on a topographic map, look for the difference in elevation between adjacent contour lines. The contour interval is usually given in the map's legend and represents the vertical distance between each contour line.

It makes it easier to count the number of contour lines.
lower.
An Index Contour
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
When a V-shaped contour line points downhill, it means that the contour line is under very low elevation. And incase your wondering about when the contour line is uphill, it means that the elevation level is very high.
