Answer 1

Answer

The letter symbols signify the name and age of the rock units in an area. The first letter refers to the geologic age, as shown above. The other letters refer to the formation name or the rock type. The geologic map of Rhode Island is a good example of how the symbols are used.

A geologic map shows the distribution of materials at or near the Earth's surface.
