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.

What is hachures?
Hachures are short, parallel lines used in cartography to indicate the steepness of slopes on a map. The lines are typically drawn perpendicular to contour lines, with the spacing or thickness of the lines used to represent the gradient of the slope. Hachures give a visual representation of the terrain in a two-dimensional map.
What do hachures on a contour indicate?
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.
Contour lines that touch or overlap on a topographic map indicate a .?

The heaviest contour lines on a topographic map are?
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.
Contour lines that touch or overlap on a topographic map indicate a?
Contour lines that touch or overlap on a topographic map indicate a sharp change in elevation, representing a steep slope or a vertical feature like a cliff or a ridge. These clustered contour lines help visualize the terrain's three-dimensional shape and can warn hikers of challenging topography.
Hatchur lines would most likely be drawn on a topographic map to indicate a?
Hatchur lines, or hachures, are used on topographic maps to indicate the steepness of slopes or the direction of landforms. They appear as short, parallel lines that are drawn on the downhill side of a contour line, helping to represent terrain features like ridges and valleys. The density and orientation of the hachures provide visual cues about the gradient and relief of the landscape.

What do closed circles on a topographic map mean?
Closed circles on a topographic map represent contour lines that indicate a hill or a mountain. The innermost circle typically signifies the highest point of elevation, with elevation decreasing as one moves outward. If the closed circle has hachures (small lines) pointing inward, it represents a depression or a bowl-shaped area instead.
What do the small loop dot on top of a topographic map indicate?
The small loop dot on a topographic map indicates a depression or a low point in the terrain, often referred to as a depression contour. These features are shown with contour lines that form closed loops with hachures (short lines) pointing inward, distinguishing them from hills or peaks. This notation helps map users identify areas where the land dips below the surrounding elevation.

What do closely spaced contour lines on a topographic map indicate?
Closely spaced contour line on a topographic map shows that the land is steep.

What does red indicate on a topographic map?
Low pressure which can mean storminess.
When contour lines that touch or overlap on a topographic map what does it indicate?
it connects to the points of Hawaii and Alaska
What On a topographic map contour lines that are close together indicate a .?
Contour lines that are close together on a topographic map indicate an area of steep slope. If they essentially overlap you have a cliff.
What color is normally used to indicate contour lines on topographic map?
black
