The <u>scale</u> of a map is the ratio of a distance on the map to the corresponding distance on the ground. The symbol used on a map to represent and find distance is a <u>scale</u><u>.</u>
Also called as the terrain is the variation that exists in the amount of the relief of the surface and difference is between the highest and lowest dimensions.
The relief can be shown of a topographic map and this represents the elevation for the vales reduced to the mean sea levels and thus shows the variations in height in terms of the contours on the land surfaces.
