uniformitarianism theory

The concept that "the present is the key to the past" was developed by the Scottish geologist James HUTTON (1788); the concept consists of the principle that geological processes in the past operated according to the same natural laws that apply today and was given the name uniformitarianism by Sir Charles LYELL
Uniformitarianism, or Actualism. ? 2. Multiple Working Hypotheses. ? 3. Principle of Parsimony. ? 4. Inductive - Deductive Reasoning. ? 5. Scientific Proof vs. Absolute. Proof. ? 6. Retrodiction – prediction in a backward direction. ? Uniformitarianism was developed by James Hutton in the 1790's. ? Charles Lyell in the 1830's.

14 Sep 1970 INTRoDucTION·. The history of geology has of ten been expounded, in the fashion of a fairy tale, as a battle between good and evil. Neptunism is black, Plutonism white; Catastrophism is black, Uniformitarianism white. In the 18th century darkness reigned until, through Hutton, suddenly all became light.
These two rocks are mined from Paleocene and Eocene strata near Andersonville in Sumter and. Macon Counties. Both require intense chemical weathering of aluminosilicate minerals like feldspar to form. The required intensity only occurs in tropical rainforests. The closest tropical rainforest is in Jamaica or Cuba. Explain.
Abstract, Catastrophism in the Earth sciences is rooted in the view that Earth signifies its causative processes via landforms, structures and rock. Processes of types, rates and magnitudes not presently in evidence may well be signified this way. Uniformitarianism, in contrast, is a regulative stipulation motivated by the
Evidence for uniformitarianism. • We haven't encountered any circumstances yet in which physical laws do not operate. • We can witness geologic processes and then look at the evidence they leave behind. • We can witness modern catastrophes and see the evidence they leave behind. • Abundant evidence of an ancient
14 Jan 2011 Basic physical and chemical processes that apply to the present apply to the past. – “The present is the key to the past". – Care must be taken. • Rates change!! • Processes that existed in the past may not exist today. • Understanding uniformitarianism is criecal to the study of geomorphology. Geomorphic
1 Dec 2007 The concept of uniformitarianism is commonly oversimplified in geological textbooks as "the present is a guide to interpreting the past" (or words to that effect). This explanation, however, is not correct about the true meaning of uniformitarianism. In order to understand uniformitarianism, one must examine
9 Oct 2017 Request (PDF) | Reviewing the term u | Uniformitarianism is a classical term of the geological sciences, coined in 1832 by Whewell to indicate a specific part of Lyell's hypothesis. However, over the years uniformitarianism has been used with different meanings, finally becoming synonymous with the
