Answer:
a. the depth of inquiry or the amount of details.
Step-by-step explanation:
In geography, scale refers to ratio between the distance on a map and the distance in the actual world. Therefore, scale tells us the depth of inquiry or the amount of details that are included in a particular map. A scale also allows us to compare a map with the real world and correctly interpret the comparison. This concept can become quite complicated when we take into account the curvature of the Earth.
