Scales are used to represent proportional measurement. They are mostly used to represent the proportion of real life dimension to the figure on paper or a computer system.
By use of scale we can represent a large detail area with proportionate sizes on paper.
Scales are used extensively in map making or cartography.
Objects on map are usually represented proportionately with their dimension on the ground.
There are different ways of representing a scale.
There is relative fraction, statement scale and bar scale.
An adept map reader should be able to translate between map and real life data.
Therefore, the correct choice is that scales represent proportional measurement.
What do ice cores tell us about the relationship between global temperatures and greenhouse gas concentrations? Ice cores show us that temperatures and CO2 concentrations are always closely correlated.
