What is geologic actualism?
Geologic actualism, also known as uniformitarianism, is the principle that the processes shaping the Earth today are similar to those that occurred in the past. It suggests that by studying current geological processes, scientists can infer the history of the Earth's development. This concept underpins much of modern geology, emphasizing that slow, gradual changes, alongside occasional catastrophic events, have shaped the planet over geological time. Overall, it asserts that "the present is the key to the past."
What is a synonym for uniformitarianism?
