Due to this, through maps, it is possible to visually show cities, states, regions countries, etc. In this context, a series of maps can be used to show the evolution or change of national borders because this is part of political features. Also, other aspects such as policies, beliefs, or economic events are not geographical and due to this cannot be depicted through maps.

To determine the age of sedimentary rock, geologists must relate the sedimentary rock to datable masses of igneous rock.
