Uniformitarianism Geology Definition

Uniformitarianism is one of the most important unifying concepts in the geosciences. It states that changes in the earths crust throughout history have resulted from the action of uniform continuous processes that are still occurring today.

It is fundamental to geologic thinking and the science of geology.

Uniformitarianism geology definition. It was the centerpiece of James Huttons 1795 geology book Theory of the Earth with proofs and illustrations. And the history of life was no different. In this work Hutton proposed that the causes acting on the world today also acted in the past.

Uniformitarianism also known as the Doctrine of Uniformity or the Uniformitarian Principle is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe. Which was refined by John Playfair and popularised by Charles Lyells Principles of Geology in 1830. What does uniformitarianism mean.

Uniformitarianism is a geological theory that describes the processes shaping the earth and the Universe. Lyells uniformitarianism was the ruling dogma of geology for almost 150 years until the late 1970s when neocatastrophism began to emerge and with it came reinterpretations of the geological record. Uniformitarianism is one of geologys essential assumptions.

Uniformitarianism is a concept created by Charles Lyell to describe his version of geology. Scientists today know that some earth-changing processes are not at play today such as massive solar debris assaulting the earth. The term uniformitarianism was coined by William Whewell.

Uniformitarianism is the idea that the same physical laws of today have always operated. Uniformitarianism is defined in the authoritative Glossary of Geology as the fundamental principle or doctrine that geologic processes and natural laws now operating to modify the Earths crust have acted in the same regular manner and with essentially the same intensity throughout geologic time and that past geologic events can be explained by phenomena and forces observable today. The principle of uniformitarianism says that the present is the key to the past.

The doctrine that all geologic changes may be explained by existing physical and chemical processes as erosion deposit. This concept states that all processes that change the earth remain the same throughout time. Like Hutton Lyell viewed the history of Earth as being vast and directionless.

Hutton a Scottish farmer and physician is considered to be the founder of modern geologic thought and was the first to recognize and describe the cyclic processes of the Earth. Look it up now. Uniformitarianism in geology the doctrine suggesting that Earths geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity accounts for all geologic change.

This theory states that the forces and processes observable at earths surface are the same that have shaped earths landscape throughout natural history. His widely read Principles of Geology presented an empirically formidable argument supporting Huttons thesis that all past changes on the globe had been brought about by the slow agency of existing causes I. Lyells version of geology came to be known as uniformitarianism because of his fierce insistence that the processes that alter the Earth are uniform through time.

This means that the rocks of the Earth were formed by processes which we can see operating today. It refers to invariance in the metaphysical principles underpinning science such as the constancy of. Uniformitarianism definition is - a geologic doctrine that processes acting in the same manner as at present and over long spans of time are sufficient to account for all current geological features and all past geological changes.

This idea was diametrically opposed to the ideas of that time period which were based on a biblical interpretation of the history of the Earth. Uniformitarianism is a theory based on the work of James Hutton and made popular by Charles Lyell in the 19 th century. This principle has had a profound impact on the science of geology.

Uniformitarianism is the name given to the idea that natural processes behave more or less in the same way today as they have throughout the past and will. This concept developed in the late 1700s suggests that catastrophic processes were not responsible for the landforms that existed on the Earths surface.
