Contours - How height and shape of the land can be shown on a map

Contours are brown lines on a map that join places with the same height.
Every point along a contour line is the same height as is stated.
Lines are drawn at common intervals (equal distance apart).
The closer the contours are together, the steeper the slope.
The contour interval is always constant (the same).
