Quizplus · Accepted Answer

Uniformitarianism is the principle that the same physical processes that are observed in the present have been operating throughout Earth's history. It suggests that geological and evolutionary processes occur at a gradual and uniform rate, rather than sudden and catastrophic events (as proposed by catastrophism). Parallelism is not a widely recognized principle in geology, and statis (or steady-state) is not related to the concept of maintaining the same physical processes throughout Earth's history.
