What is the difference between uniformitarianism and catastrophism quizlet?
What is the fundamental difference between uniformitarianism and catastrophism? Catastrophism- states that Earth's landscapes developed over short time spans primarily as a result of great catastrophes. Uniformitarianism- one of the fundamental principles of modern geology.

What is the difference between uniformitarianism and Actualism?
Uniformitarianism is the application of actualism. Uniformitarianism is when the theory of actualism is used to interpret the past. What's weathering? Over time, the climate breaks down rocks.
What are some examples of catastrophism?
This mass extinction is an example of catastrophism. Meteorite impacts, ice ages, and ocean acidification are all catastrophic phenomena that can cause mass extinction events. In fact, it's pretty likely that all five major mass extinctions are the result of catastrophism.
What is theory of 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).
Is catastrophism or uniformitarianism more accurate?
In addition, uniformitarianism laid the foundation for Darwin's theory of evolution, which also needed an old earth to be credible. So uniformitarianism dethroned catastrophism and evolution dethroned biblical creationism and both became the dominant theories in academia and science until the present time.
What are the key differences between gradualism and catastrophism?
What are the key differences between the theories of gradualism and catastrophism? Gradualism emphasizes slow changes on Earth over long periods of time, while catastrophism emphasizes change through natural disasters.
What is the difference between uniformitarianism and gradualism?
Gradualism is the view that large-scale changes occurs by the accumulated effects of small changes over long periods of time, rather than by rare cataclysmic events of massive effect. Uniformitarianism is the view that the same forces that shaped the world in the past continue to operate today.
What is the age of Earth according to catastrophism and uniformitarianism?
According to catastrophism, the Earth was created 4004 B.C. and is only a few thousand years old. According to uniformitarianism, there was no sign of a beginning or an end of all geologic processes, which occurred over thousands or millions of years. You just studied 58 terms!
What are 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 catastrophism in simple words?
Definition of catastrophism : a geologic doctrine that changes in the earth's crust have in the past been brought about suddenly by physical forces operating in ways that cannot be observed today — compare uniformitarianism. Other Words from catastrophism Example Sentences Learn More About catastrophism.
What is theory of uniformitarianism?
Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.
What’s the meaning of uniformitarianism?
Definition of uniformitarianism : a geologic doctrine that processes acting in the same manner as at present and over long spans of time are sufficient to account for all current geological features and all past geological changes — compare catastrophism.
What’s the difference between catastrophism and gradualism?
Gradualists explained geological features as the result of slowly acting processes such as erosion, while catastrophists argued that Earth had been shaped mainly by a series of violent events or catastrophes, whether over a relatively short time (6,000 to 10,000 years) or over many millions of years.
What is the theory of uniformitarianism?
Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.
Which is more correct catastrophism or uniformitarianism?
In addition, uniformitarianism laid the foundation for Darwin's theory of evolution, which also needed an old earth to be credible. So uniformitarianism dethroned catastrophism and evolution dethroned biblical creationism and both became the dominant theories in academia and science until the present time.
What is uniformitarianism in simple words?
This is known as uniformitarianism: the idea that Earth has always changed in uniform ways and that the present is the key to the past. The principle of uniformitarianism is essential to understanding Earth's history.
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 an example of uniformitarianism?
Uniformitarianism is the concept that natural geological processes which occur today have occurred at approximately the same rate and intensity as they have in the distant past and will continue to do so in the future. As an example, think of a volcano which erupts, spewing out lava which forms basalt.
What is Uniformitarian principle?
Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.
What is the opposite of uniformitarianism?
Catastrophism is the doctrine that Earth's history has been dominated by cataclysmic events rather than gradual processes acting over long periods of time.
What is the difference between catastrophism and gradualism?
Gradualists explained geological features as the result of slowly acting processes such as erosion, while catastrophists argued that Earth had been shaped mainly by a series of violent events or catastrophes, whether over a relatively short time (6,000 to 10,000 years) or over many millions of years.
What are the three principles of uniformitarianism?
The theoretical system Lyell presented in 1830 was composed of three requirements or principles: 1) the Uniformity Principle which states that past geological events must be explained by the same causes now in operation; 2) the Uniformity of Rate Principle which states that geological laws operate with the same force …
What is the analogy of catastrophism?

What are catastrophic processes?
Proponents of catastrophism proposed that each geological epoch ended with violent and sudden natural catastrophes such as major floods and the rapid formation of major mountain chains.
What is the opposite of Uniformitarianism?
Catastrophism is the doctrine that Earth's history has been dominated by cataclysmic events rather than gradual processes acting over long periods of time.
