Its happen only in the case of overhanging cliff
A very steep regionClosely spaced contour lines indicate a very steep slope.Conversely, widely spaced lines indicate areas that are nearly flat.-Leftover.Tech
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
Contour lines represent connecting points of equal elevation on a topographic map.
A contour interval for a given topographic map always the same is true; not false.
The closer the contour lines, the steeper is the slope.
Contour lines are used in Topography to show the elevation of the land on a map. When looking at a map the contour lines look very similar to how a calm lake would appear.

Those lines representing elevation on a map are called contour lines. The difference in elevation between two of these lines is called the contour interval. Different maps use different contour intervals based on the scale of the map, or in other words, the size of the contour interval is based on how zoomed in and detailed the map is. Sometimes a map will have darker and thicker contour intervals. This is called the Index Contour Interval. Index contour intervals appear less frequently and represent a larger elevation change. It helps you figure out the amount of a large elevation difference faster because usually they are multiples of 100 or 1000, making them easier to add up.

A contour chart is a map that shows contour lines. A good example of this is a topographic map.

The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
Contour lines show levels of elevation, where there are hills and valleys on a map
Contour lines show elevation.
