What is another word for 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 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.
Which of the following is the best definition of uniformitarianism?
Uniformitarianism says that the processes that shape Earth are the same throughout time. That means if we observe a process shaping Earth today, we can assume the same process shaped Earth in the past and will shape Earth in the future all over the planet and even on other planets.
What is a relative age?
1. n. The approximate age determination of rocks, fossils or minerals made by comparing whether the material is younger or older than other surrounding material.
How present is the key to the past?
The present is the key to the past… The idea that the same natural laws and processes that operate on Earth today have operated in the past is an assumption many geologists use in order to better understand the geologic past. This idea is known as uniformitarianism, also defined as “the present is the key to the past”.
What is the law of original horizontality?
The LAW OF ORIGINAL HORIZONTALITY states that a series of sedimentary layers will generally be deposited in horizontal layers.
What is a Reviewal?

What is Charles Lyell’s theory?
Lyell argued that the formation of Earth’s crust took place through countless small changes occurring over vast periods of time, all according to known natural laws. His “uniformitarian” proposal was that the forces molding the planet today have operated continuously throughout its history.
What is an example of relative age?
relative agethe age of an object in comparison with the age of other objects; for example, one rock is older than another rock.
What can relative age indicate?
Determining the Relative Ages of Rocks
The relative age of a rock is its age in comparison with other rocks. If you know the relative ages of two rock layers, you know which is older and which is younger, but you do not know how old the layers are in years.
Which is an example of relative dating?
For example, if a valley is formed inside an impact crater, the valley must be younger than the crater. Craters are very useful in relative dating; as a general rule, the younger a planetary surface is, the fewer craters it has.
Who proposed the law of uniformitarianism?
James Hutton. Along with Charles Lyell, James Hutton developed the concept of uniformitarianism. He believed Earth’s landscapes like mountains and oceans formed over long period of time through gradual processes.
What is the difference between 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.
