Explanation:
Detailed explanation-1: -Uniformitarianism suggests that the geological features of Earth were created in slow incremental changes such as erosion. In contrast, catastrophism states that the Earth has largely been sculpted by sudden, short-lived, violent events. So, this is the key difference between uniformitarianism and catastrophism.
Detailed explanation-2: -According to uniformitarianism, fossils are formed over a period of centuries via gradual processes, such as sedimentation. Today, geologists accept this explanation for the formation of many fossils. However, they also know that some fossils were also formed via catastrophic events.
