Geologic Time Periods Time Scale Facts Britannica In formulating his theory of evolution by natural selection, charles darwin was inspired by charles lyell’s principles of geology , recognizing in lyell’s view of earth history the almost limitless expanse of time he thought necessary to understand evolution . in the 21st century, an increasingly well resolved timetable of evolution. The history of the earth can be organized chronologically according to the geologic time scale, which is split into intervals based on stratigraphic analysis. [2] [21] the following five timelines show the geologic time scale to scale. the first shows the entire time from the formation of the earth to the present, but this gives little space.
Evolution Of Earth Origin Theories Geological Time Scale Earth’s interior, the enormous size of the planet and its structures, the long expanse of geological time, and the vast diversity of materials present challenges to studying earth materials. break throughs in this area are now at hand, however; new analytical tools and advanced computing capabilities are improving the study and simula. The geologic time scale is the “calendar” for events in earth history. it subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages. the enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata. According to the hypothesis, the earth was originally shaped like a ball of stuff that exploded to create the cosmos as we know it today. this procedure took around 13.7 billion years to complete. after approximately 300,000 years of this evolution process, the matter condensed to obtain the current shape of the universe. The geologic time scale is a way of representing deep time based on events that have occurred throughout earth's history, a time span of about 4.54 ± 0.05 ga (4.54 billion years). [5] it chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or.

The geological history of the earth follows the major geological events in earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk shaped mass of dust and gas left. The pregeologic period. from the point at which the planet first began to form, the history of earth spans approximately 4.6 billion years. the oldest known rocks—the faux amphibolites of the nuvvuagittuq greenstone belt in quebec, canada—however, have an isotopic age of 4.28 billion years. there is in effect a stretch of approximately 300.
