Let’s Recall

• An imaginary line on the surface joining the points of equal elevation is known as a contour.
• A map showing contour lines is known as contour map.
• Each topographic feature such as mountains, ridges, cliff s, passes or cols are represented by a
unique pattern of contour lines.
• There are diff erent kinds of settlements—permanent and temporary, nucleated, linear,
dispersed and radial.
