Wired Faculty App

Differentiate between the contours and form lines.

Answer

Contours : A contour is an imaginary line (drawn on map) joining the points having the same elevation above the sea-level.

Form Lines : These are broken lines. This method is used in association with contours to show the hilly or mountainous country. They are drawn without any precise measure units. They indicate the minor details which are not shown by contours.
