Geologists have divided the Earth's history into Eras -- broad spans based on the general character of life that existed during these times -- and Periods -- shorter spans based partly on evidence of major disturbances of the Earth's crust.
The geological column is not strictly limited to evolutionary thought. They believed more in catastrophism than in the uniformitarianism that prevails today.
In doing so Hutton unwittingly fulfilled a prediction in II Peter 3:3-6.
The phrase, "All things continue as they were from the beginning of the creation" is essentially ancient Greek for uniformitarianism.
The average weather conditions of a region over time are used to define a region's climate.
It supposedly grew as a result of numerous impacts early in its history and then cooled over billions of years. About 1785, James Hutton developed an idea called uniformitarianism.Important in its development were studies on the origins of the various kinds of rocks (petrology), coupled with studies of rock layering (stratigraphy) and the fossils they contain (paleontology).The full sequence of layers was compiled following the study and correlation of rock layers on many continents, and was largely based on the interpretation that layers of sedimentary rock formed over millions and even billions of years at uniform geologic rates.It is largely assumed by creation scientists that the differential fossil layers are due to the varying times of death of the organisms that died during the global flood (see fossil sorting).Evolutionists have subsequently added the so-called "periods" and "eras" in order to effectively make the geologic timeline fit within the ever-more popular theory of evolution.
