Geologic time map.

The figure of this geologic time scale shows the names of the units and subunits. Using this time scale, geologists can place all events of Earth history in order without ever knowing their numerical ages. The specific events within Earth history are discussed in Chapter 8.

Introduction. Geologic maps are maps that depict the rock units that crop out at Earth’s surface.
