Chasmism.
the antonym for uniformitarianism is CATASTROPHISM. Uniformitarianism means to take a long period of time for the Earth to form. Catastrophism means the Earth quickly formed.
Uniformitarianism requires the assumption of vast time-lines, and catastrophism can function with or without assumptions of long timelines
Some combination of both.
False Catastrophism is not the idea that the present is the key to the past. Uniformitarianism is the idea that the person is the key to the past.
An earthquake would support the principle of catastrophism. The principle of catastrophism suggests that significant geological events, such as earthquakes, are caused by sudden, violent forces. This is in contrast to uniformitarianism, which argues that geological processes occur gradually over long periods of time.
Uniformitarianism is a principle that geologic processes that occurred in the past can be explained by current geologic processes. So, it is the idea that the same geologic processes that same Earth today have been at work during all of Earth's history. Catastrophism is a principle that states that geologic change occurs suddenly. Catastrophies include floods, asteroids, earthquakes, etc. Today, modern geology is based on the idea that gradual geologic change is interrupted by catastrophies.
Catastrophism was the theory that the Earth had largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This was in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features.
The science of geology has changed because scientists now realize that not all geologic changes are uniformitarianism, and that catastrophism exists.
because before when they came up with both theorys, they believed the earth was only a few thousand years old . Therefore they believed in catastrophism. and now they have evidence to why uniformitarism could be right and for the earths age .
the grand canyon
a Grand Canyon is nothing but a big erosion.........
Copper Canyon (Spanish: Cañon del Cobre) is such landmark.
