The concept that suggests slow geologic processes observed today have been at work throughout Earth's history is known as uniformitarianism. This principle posits that the geological processes we witness, such as erosion, sedimentation, and volcanic activity, operate in consistent ways over time. This idea implies that by studying current geologic processes, we can infer how the Earth has changed throughout its history.

Uniformitarianism fundamentally contrasts with the notion of catastrophism, which emphasizes that Earth's landscapes have primarily been shaped by sudden, violent events, such as earthquakes or meteorite impacts. While these events certainly have an impact, uniformitarianism argues that the gradual processes are equally, if not more, significant in shaping the planet over geological time.

This principle laid the groundwork for modern geology and helped to establish the concept of deep time, allowing scientists to understand Earth's history as a long, continuous progression rather than a series of discrete disasters. Ultimately, uniformitarianism provides a framework for interpreting geological records and understanding the Earth's past environment and conditions based on observable evidence.
