29 Geologic Time Scale Drawing
Hendricks for the earth@home project. Web the geologic time scale is a system used by scientists to describe earth's history in terms of major geological or paleontological events (such as the formation of a new rock layer or the appearance or demise of certain lifeforms). The north american stratigraphic code (north american commission on stratigraphic nomenclature, 2005) recommends abbreviations for ages in si (international system of units) prefixes coupled with a for annum: Mark carnall lost worlds revisited science Using a variety of techniques and dating methods, geologists have been able to ascertain the age of the earth, as well as major eras, periods, and epochs within earth's history.
Web the geologic time scale is the “calendar” for events in earth history. Note that the geologic time scale above is not scaled to time and mostly represents the phanerozoic eon. Web the geologic time scale is a system for organizing the history of the earth into units of time, from the smallest to the largest, based on the events and processes that have occurred. Web the geologic time scale drawing is a visual representation of earth's history, depicting the vast expanse of time that spans billions of years. The time scale is continuously being updated as we learn more about the timing and nature of past geological events.
Figure 12.2 shows you a different way of looking at the geologic time scale. It provides a chronological framework that helps scientists understand the sequence of events that have shaped our planet and the evolution of life on it. Web using a 2.5 m long roll of paper, create your own geologic time scale using the following scale: It is based almost entirely upon careful observations of the distributions of fossils in time and space. While the units making up the time scale are called geochronologic units, the actual rocks formed during those specific time intervals are called chronostratigraphic units.
