Concept:Relief representation on maps involves showing the physical shape and height of the land.
Explanation:Contours are lines that join points of equal height above sea level.
Form lines are similar to contours but do not show exact heights.
Hachures are short lines drawn in the direction of the slope to show steepness.
These three methods directly indicate the form and elevation of the terrain.
A dot map, however, is a thematic map used to show the quantity or distribution of data, such as population or crops.
It does not show the shape or relief of the land surface.
Therefore, among the options given, the dot map is not a method of representing relief.
The correct answer is the one that stands out as unrelated to relief.
Answer:C. dot map
