Geologic Time Scale Drawing
Geologic Time Scale Drawing - 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. It is based almost entirely upon careful observations of the distributions of fossils in time and space. They study sedimentary rock layers, or strata, and fossils to understand past events.

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 time scale is continuously being updated as we learn more about the timing and nature of past geological events. Web geologic time scale showing the geologic eons, eras, periods, epochs, and associated dates in millions of years ago (mya). It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). They study sedimentary rock layers, or strata, and fossils to understand past events. Understanding the divisions of time in the geologic time scale is crucial for comprehending the history of our planet and the evolution of life on earth.
