Which statement best describes the concept of uniformitarianism?
Which statement best describes the principle of uniformitarianism? Uniformitarianism says that the processes that shape Earth are the same throughout time.
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 is the 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 was Lyell’s theory of uniformitarianism?
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 are the 3 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 …
