no thwy cant because there is never a elevation of zero
The closer the contour lines, the steeper is the slope.
The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
The main topographic map rules include contour lines never crossing, contour lines close together represent steep terrain, contour lines spread out represent flat terrain, and elevation is indicated by the contour lines.
The formula to calculate the contour interval of a map is the difference in elevation between two contour lines divided by the number of contour lines crossed. This provides the elevation change between each contour line on the map.
Contour lines show levels of elevation, where there are hills and valleys on a map
Contour lines that touch or overlap on a topographic map indicate a
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"
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
Contour lines that touch or overlap on a topographic map indicate a
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
The closer the contour lines, the steeper is the slope.
Contour lines show elevation.
a TOPOGRAPHICAL MAP shows the contour of the lines
Contour lines on a map represent points of equal elevation. The difference in elevation between any two contour lines is called the contour interval, which is usually indicated on the map legend. By knowing the contour interval, you can determine the steepness of the terrain in that specific area.
A contour chart is a map that shows contour lines. A good example of this is a topographic map.
