elevation
The proximity of contour lines indicates the steepness of the terrain in a particular area. Closely spaced contour lines suggest a steep slope, while widely spaced contour lines suggest a gentle slope.
elevation
Slope, or percent of grade.
The steeper the slope, the contour lines go further along the area. You can also determine the flatness of the area with these lines.
On a topographical map, a contour line indicates a change in elevation. When the lines are close together, the elevation is changing rapidly.
If the contour lines on a topographic map are close together, that area is a steep slope. If the contours have wide spaces in between then the terrain is relatively flat. Many close contour lines mean the elevation is changing rapidly.
Contour lines that are close together on a topographic map indicate an area of steep slope. If they essentially overlap you have a cliff.
If the contour lines on a topographic map are close together, that area is a steep slope. If the contours have wide spaces in between then the terrain is relatively flat. Many close contour lines mean the elevation is changing rapidly while sparse contour lines mean elevation changes very little.
In a steep area, contour lines are closer together, indicating a rapid change in elevation over a short distance. In comparison, in a flat area, contour lines are more spaced out, showing a gentle slope or minimal change in elevation. Steeper areas will have more contour lines packed closely together, while flat areas will have contour lines spaced further apart.
The closer the contour lines the steeper the slope.
A plain or flat area on a contour map is recognized by contour lines. Thick contour lines have elevations printed on them periodically. They can also use supplemental contours that represent smaller vertical distances using dashed lines.
The contour lines around the mountain would be close together, indicating a steep slope, while the contour lines around the low hills would be more spaced out, indicating a gentler slope.
