Geologic time map
A geologic map is a map that shows the distribution of bedrock that is exposed at the Earth’s surface or buried beneath a thin layer of surface soil or sediment. A geologic map is more than just a map of rock types: most geologic maps show the locations and relationships of rock units. Each rock unit is identified on the map by a symbol of ...The Geologic Time Scale is divided by the following divisions: Standard 8-2.4: Recognize the relationship among the units—era, epoch, and period—into which the geologic time scale is divided. Eons: Longest subdivision; based on the abundance of certain fossils

Most maps that we use in our day-to-day lives are two-dimensional: they are flat and show features like roads, cities, and natural features such as lakes and rivers. Hikers and other outdoor enthusiasts may be familiar with topographical maps, which add a third dimension: elevation. Geological maps. One powerful representation of the geometry of rock structures is a geological, or geologic map. Geological maps are created through the process of mapping in which outcrops are visited in the course of fieldwork, described, and recorded on a topographic base map. The result is an outcrop map in which the …

Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way.Webster built the map as a web application that sits on top of another map which visualizes geological models created by geologist and paleogeographer Christopher Scotese.
