    How does bedrock help Geologists identify rock formation?
    Bedrock also helps geologists identify rock formations. Rock formations, sometimes called geological or lithostratigraphic units, are sections of rock that share a common origin and range. Rock formations help geologists create geologic maps. Geologic maps often display bedrock formations, usually in bright colors.

      The surface of the bedrock beneath the soil cover (regolith) is also known as rockhead in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.
