Apart from the Late Heavy Bombardment, events on other planets probably had little direct influence on the Earth, and events on Earth had correspondingly little effect on those planets.
Construction of a time scale that links the planets is, therefore, of only limited relevance to the Earth's time scale, except in a Solar System context.
The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time.
It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.
The existence, timing, and terrestrial effects of the Late Heavy Bombardment are still debated.
In Ancient Greece, Aristotle (384-322 BCE) observed that fossils of seashells in rocks resembled those found on beaches – he inferred that the fossils in rocks were formed by living animals, and he reasoned that the positions of land and sea had changed over long periods of time.In East Asia and Siberia, the same unit is split into Alexian, Atdabanian, and Botomian stages.A key aspect of the work of the International Commission on Stratigraphy is to reconcile this conflicting terminology and define universal horizons that can be used around the world.The first three of these can be referred to collectively as the Precambrian supereon.Eons are divided into eras, which are in turn divided into periods, epochs and ages.This clock representation shows some of the major units of geological time and definitive events of Earth history.Tags: Adult Dating, affair dating, sex dating
