The difference in elevation between the highest and lowest contour lines on a topographical map is called a contour interval.
contour interval
A contour interval shows a change in elevation on a topographical map. If the contour interval is 20 then the elevation change between two contour lines is 20 meters
the elevation difference between two adjacent contour lines.
the contour interval is the difference in elevation between contour lines that are next to each other
The Contour Interval.
Called both Elevation Lines or Contour Lines
Contour lines show elevation on a topographical map. These lines connect points of equal elevation above sea level, with lines close together representing steep terrain and lines further apart indicating gentler slopes.
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
True.
Contour interval.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
contour interval
Contour lines show elevation differences on topographic maps. On other maps, a coloured grid can show changes in elevation (these are called digital elevation models or DEMs).
