The principle that discusses sudden and catastrophic changes in geological formations is catastrophism. This concept is grounded in the idea that Earth's landscape has been shaped primarily by a series of abrupt, significant events such as volcanic eruptions, earthquakes, and massive floods. Catastrophism emphasizes that these events have played a crucial role in the Earth's history and have led to the formation of many geological features observed today.

In contrast, gradualism proposes that geological changes occur slowly and incrementally over long periods of time. This principle emphasizes a more continuous process of change rather than sudden events. Evolutionary Theory, while related to biological changes over time, does not specifically address geological changes or processes. Similarly, the concept of Agents of Change refers to various forces that cause change, such as wind, water, or ice, but does not specifically focus on the idea of sudden, catastrophic events like catastrophism does.
