Principles. 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 ...
Detailed logarithmic timeline – Timeline of the universe, Earth, and mankind; Earth phase – Phases of the Earth as seen from the Moon; Evolutionary history of life; Future of Earth – Long-term extrapolated geological and biological changes of planet Earth; Geological history of Earth – The sequence of major geological events in Earth's past
Geologic time is the timescale used to calculate dates in the planet's geologic history from its origin (currently estimated to have been some 4,600 million years ago) to the present day. Radiometric dating measures the steady decay of radioactive elements in an object to determine its age. It is used to calculate dates for the older part of ...
1743 – Dr Christopher Packe produces a geological map of south-east England. 1746 – Jean-Étienne Guettard presents the first mineralogical map of France to the French Academy of Sciences. 1760 – John Michell suggests earthquakes are caused by one layer of rocks rubbing against another. 1776 – James Keir suggests that some rocks, such ...
Timeline geological timescale. 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 for the most recent eon. The second timeline shows an expanded view of the most recent eon. In a similar way, the most recent era is ...
