What are 3 examples of uniformitarianism?
Good examples are the reshaping of a coastline by a tsunami, deposition of mud by a flooding river, the devastation wrought by a volcanic explosion, or a mass extinction caused by an asteroid impact. The modern view of uniformitarianism incorporates both rates of geologic processes.
What is known as age of catastrophism?

What do the data from Mount Saint Helens tell us about the time it takes to form stratified rocks?
What do the data from Mount Saint Helens tell us about the time it takes to form stratified rocks? Thus, the data from Mt. St. Helens tell us that canyons form rivers, not that rivers form canyons.
What causes catastrophism?
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 doctrine generally is associated with the great French naturalist Baron Georges Cuvier (1769–1832).
What is Uniformitarianism and catastrophism?
Both theories acknowledge that the Earth’s landscape was formed and shaped by natural events over geologic time. While catastrophism assumes that these were violent, short-lived, large-scale events, uniformitarianism supports the idea of gradual, long-lived, small-scale events.
What is the youngest type of rock?
