What do contours show?

Contour Rules Every point on a contour is the exact same elevation – contour lines connect points of similar elevation The elevation between two adjacent contour lines of different elevation on a topographic map is the contour interval (1 m, 5 m 10 m) Contour lines only merge when there is a vertical cliff

What do contours show?

The closer the lines are together, the steeper the slope, the farther they are apart, the gentler the slope. Contour lines form a V pattern when crossing a stream or slope. The V always points upstream Exact elevation on the topographical map is given by the use of a BENCH MARK (BM or x . or
