who is credited with proposing the principle of uniformitarianism
Uniformitarianism In geology, uniformitarianism has included the gradualistic concept that "the present is the key to the past" (that events occur at the same rate now as they have always done); many geologists now, however, no longer hold to a strict theory of gradualism.[6] Coined by William Whewell, the word was proposed in contrast to catastrophism[7] by British naturalists in the late 18th century, starting with the work of the geologist James Hutton in his many books including Theory of the Earth[8]. Hutton's work was later refined by scientist John Playfair and popularised by geologist Charles Lyell's Principles of Geology in 1830.[9] Today, Earth's history is considered to have been a slow, gradual process, punctuated by occasional natural catastrophic events.
