They show elevation
On a map, contour lines are the best method of showing relief ( the ups and downs of a land surface)
(:
Contour lines measure elevation or altitude. They connect points of equal elevation on a map, helping to visualize the shape and slope of the land. Closer contour lines indicate steeper terrain, while farther apart lines suggest flatter areas.
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 lines.
Contour lines connect points with the same elevation or altitude. These lines are used on maps to help visualize the shape and elevation of the terrain.
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.
Contour interval.
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
index contour lines have numbers contour lines dont
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
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.
Contour lines connect points with the same elevation or altitude. These lines are used on maps to help visualize the shape and elevation of the terrain.
The closer the contour lines, the steeper is the slope.
