Have you seen a news clip or a video showing a volcano erupting, or an earthquake shaking a city? One of the interesting things about those events is that they occur today in the same way that they have in the past. Scientists look at modern-day geologic events—whether as sudden as an earthquake or as slow as the erosion of a river valley—to get a window into past events. This is known as uniformitarianism: the idea that Earth has always changed in uniform ways and that the present is the key to the past.
