They were used to mark slopes, they tell the direction and the steepness.
however, they are not commonly used anymore as they were replaced with the use contours as they are more useful topographical survey purposes.
definition: One of the short lines used on maps to shade or to indicate slopes and their degree and direction.

On a topographic map, contour lines that are closer together indicate a steeper slope.
Hachures are marks that can be found on the contour lines that form a depression on a topographical map.
Hachure lines are a form of representation for showing the contours on a map. They point towards the steepest part of the slope. Hachure lines are an old form of showing relief, and less useful, scientifically, than contour lines.

On a topographic map, contour lines that are closer together indicate a steeper slope.
Closely spaced contour line on a topographic map shows that the land is steep.
Contour lines on a map indicate elevation. They connect points of equal elevation, showing the shape and steepness of the terrain. Closer contour lines indicate steep slopes, while spaced-out lines represent flatter areas.
Low pressure which can mean storminess.
it connects to the points of Hawaii and Alaska
Contour lines that are close together on a topographic map indicate an area of steep slope. If they essentially overlap you have a cliff.
