As geographers use the term, scale tells usa. the weight of a given commodity. b. the intrinsic character of the object or area studied. c. the relationship between earth distance and map distance. d. the length of a degree of longitude along different parallels.

Option (C)

Explanation:

A scale is usually defined as the ratio between the distance between two particular places on the map and the actual distance between the two places on the actual ground surface.

It is widely used by the geographers while studying a map, in order to explain the relationship between the map distance and the earth's distance. This scale is mentioned in the map, mostly at the bottom of the map.

For example, a map scale of 1:500000, this means that 1 centimeter on the map is equivalent to 5000 meters = 5 kilometers on the ground surface.

Thus, the correct answer is option (C).
