uniformitarianism
{i} (Geology) uniformitarian doctrine, doctrine that natural geologic processes took place in the past in the same way as they occur today
The scientific principle that natural processes operated in the past in the same way that they operate today; used especially in physics, chemistry, biology and geology
The uniformitarian doctrine
One side of a nineteenth-century geological argument about the forces that have shaped the earth; in this case, the notion was that, with the exception of volcanoes and earthquakes, the earth has been shaped by the slow, almost imperceptible working of natural processes which are still going on and can be measured The issue is this: if the laws are uniform, we can see back beyond the last major cataclysm and so can reliably talk about millions of years in the past See Catastrophism
The principle that applies to geology our assumption that the laws of nature are constant As originally used it meant that the processes operating to change the Earth in the present also operated in the past and at the same rate and intensity and produced changes similar to those we see today The meaning has evolved and today the principle of uniformitarianism acknowledges that past processes, even if the same as today, may have operated at different rates and with different intensities than those of the present The term "actualism" is sometimes used to designate this later meaning
Doctrine in geology that physical, chemical, and biologic processes now at work on and within the Earth have operated with general uniformity (in the same manner and with essentially the same intensity) through immensely long periods of time and are sufficient to account for all geologic change. In other words, the present is the key to the past. Although the term is no longer much used, the principle, originated by James Hutton, is fundamental to geologic thinking and underlies the whole development of the science of geology. See also Charles Lyell
Is a theory that rejects the idea that catastrophic forces were responsible for the current conditions on the Earth The theory suggested instead, that continuing uniformity of existing processes were responsible for the present and past conditions of this planet
The theory that geologic events in the past were caused by natural processes which are operating at the present time
A theory derived from the work of James Hutton and championed by Charles Lyell during the nineteenth century It suggests that the Earth is unchanging except for a series of cycles such as the rock cycle, and that the same processes that act on the surface of the Earth today have been the same throughout the past Uniformitarianism does not allow for the influence of catastrophies, and views the processes of the Earth as being gradual and unchanging
n the idea that geologic processes which operate at present also operated in the past in an identical manner, and geologists can therefore extrapolate on past events using present day standards or examples; termed "the present is the key to the past "
Originally a concept in geology, the precept that the processes observable in the present can also be used to explain the past
The name coined by William Whewell in 1837 to describe a view in geology championed by Charles Lyell that the rate and mechanisms of geological change operating in the modern era are sufficient to explain changes in the past It was contrasted with catastrophism More recently, uniformitarianism has been applied to any 'steady state' theory or model of historical change, including evolution (cf Gould and Eldredge's Punctuated Equilibrium theory)
The name coined by William Whewell in 1832 to describe a view in geology championed by Charles Lyell that the rate and mechanisms of geological change operating in the modern era are sufficient to explain changes in the past It was contrasted with catastrophism More recently, uniformitarianism has been applied to any 'steady state' theory or model of historical change, including evolution (cf Gould and Eldredge's Punctuated Equilibrium theory)
