Question

what is the contour line write the three characteristics of the contour line.​

Answer 1

Answer:

Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. The diagram illustrates how contour lines show relief by joining points of equal elevation.

characteristics of contour lines are:

- Horizontal distance between contour lines is inversely proportional to slope. - Uniform slopes have uniformly spaced lines. - Along plane surfaces, contour lines are straight and parallel. - Contour lines are perpendicular to lines of steepest slopes.
