A geologic map is a map of the different types of rocks that are on
the surface of the Earth. By mapping different rock types, geologists
can determine the relationships between different rock formations
which can then be used to find mineral resources, oil, and gravel
deposits. Also, you want to know what type of rock you are building on
or else you might have a Leaning Tower of Pisa or a pile of rubble
after a strong earthquake.
