(Something in nature that happens and causes a lot of damage.)
No, "gradual" typically refers to slow changes over time, while "catastrophic" describes sudden and intense changes. They are opposite in terms of the speed and scale of the geological change.
The idea that geologic change can happen suddenly is known as catastrophism. This theory proposes that Earth's geological features are mainly a result of sudden, short-lived, and violent events, rather than gradual processes over time. While some catastrophic events like earthquakes and volcanic eruptions can cause rapid geologic changes, most changes on Earth's surface are the result of slow and continuous processes such as erosion and sedimentation.
The event used to separate geologic eras is a significant change in Earth's environment or life forms, known as a mass extinction event.
Geologic forces are natural processes that shape the Earth's surface over long periods of time. These forces include tectonic plate movements, volcanic activity, erosion, and sedimentation. They are responsible for creating landscapes, mountains, valleys, and other features on Earth.

uniformitarianism
Catastrophic weather events have happened since the Earth was formed. They can happen when things in the atmosphere radically change.
The geologic principle that the same geologic processes that operate today operated in the past to change Earth's surface.
uniformitarianism
First, let's define uniformitarianism. It is the postulation that the geologic principles that operated in the past are the same as those that are operating today. The opposite view is supposed to be catastrophism, the postulation that Earth's geologic features are a result of sudden and catastrophic processes that are not currently in action today. Catastrophic events, however, are perfectly compatible with uniformitarianism, as events such as flooding can occur due to normal processes such as headward erosion toward large bodies of water, and climatic caused ice melting during periods of glaciations. Large meteor impacts have been recorded in the past, and so have eruptions of supervolcanoes. These catastrophic events are going to occur again and are considered a part of, just not a highly predictable part of, the geologic cycle.
