Catastrophism, doctrine that explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations. This is the opposite of uniformitarianism, the view held by many present-day scientists that Earth's features developed gradually over long periods of time. The geologist Charles Lyell built upon Hutton's ideas during the first half of 19th century and amassed observations in support of the uniformitarian idea that the Earth's features had been shaped by same geological processes that could be observed in the present acting gradually over an immense period of time. Omissions? Catastrophe theory is a mathematical framework that deals with discontinuous transitions between the states of a system, given smooth variation of the underlying parameters. [2] Nor did he ever make any reference to divine creation as the mechanism by which repopulation occurred following the extinction event. In 1990, a 180 kilometres (110 mi) candidate crater marking the impact was identified at Chicxulub in the Yucatán Peninsula of Mexico. This led him to believe the Earth was several million years old. [1] This is in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features. In 1923 J Harlen Bretz published a paper on the channeled scablands formed by glacial Lake Missoula in Washington State, USA. Updates? His motivation was to explain the patterns of extinction and faunal succession that he and others were observing in the fossil record. [8], Uniformitarian explanations for the formation of sedimentary rock and an understanding of the immense stretch of geological time, or as the concept came to be known deep time, were found in the writing of James Hutton, sometimes known as the father of geology, in the late 18th century. Catastrophism was a theory developed by Georges Cuvier based on paleontological evidence in the Paris Basin. [5], By contrast in Britain, where natural theology was influential during the early nineteenth century, a group of geologists including William Buckland and Robert Jameson interpreted Cuvier's work differently. “That led to a change in thinking,” Steve said. [11], In the 1950s, Immanuel Velikovsky propounded catastrophism in several popular books. [15] The impact theory does have some faults; some computer simulations show the formation of a ring or multiple moons post impact, and elements are not quite the same between the earth and moon. As a result of the influence of Jameson, Buckland, and other advocates of natural theology, the nineteenth century debate over catastrophism took on much stronger religious overtones in Britain than elsewhere in Europe.

Plants and animals living in the parts of the world where such events occurred were made extinct, being replaced abruptly by the new forms whose fossils defined the geological strata. Catastrophism, doctrine that explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations.

But Mt St Helens helped blast that idea away. According to Werner, all of the Earth’s rocks were formed by rapid chemical precipitation from a “world ocean,” which he then summarily disposed…, …witness to sudden and widespread catastrophes. Corrections? Our editors will review what you’ve submitted and determine whether to revise the article. He added extensive editorial notes to the translation, explicitly linking the latest of Cuvier's revolutions with the biblical flood. [6] Buckland spent much of his early career trying to demonstrate the reality of the biblical flood using geological evidence. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... During the late 18th and early 19th century, the leading proponent of this view was the German mineralogist Abraham Gottlob Werner. [2][3], In the early development of geology, efforts were made in a predominantly Christian western society to reconcile biblical narratives of Creation and the universal flood with new concepts about the processes which had formed the Earth. Most of the mechanisms suggested are catastrophic in nature. Since then, the debate about the extinction of the dinosaurs and other mass extinction events has centered on whether the extinction mechanism was the asteroid impact, widespread volcanism (which occurred about the same time), or some other mechanism or combination. [10], The rise in uniformitarianism made the introduction of a new catastrophe theory very difficult. Instead they believed that the earth had been shaped by the long term action of forces such as volcanism, earthquakes, erosion, and sedimentation, that could still be observed in action today. In the early development of geology, efforts were made in a predominantly Christian western society to reconcile biblical narratives of Creation and the universal flood with new concepts about the processes which had formed the Earth.

This paper suggested that a 10 kilometres (6.2 mi) asteroid struck Earth 66 million years ago at the end of the Cretaceous period. Proponents of catastrophism proposed that the geological epochs had ended with violent and sudden natural catastrophes such as great floods and the rapid formation of major mountain chains.
