Transcription: Uniformitarians use a combination of slow deposition and erosion to explain the differences in the geology from region to region in the world. Consider for example these two regions of the world. Initially, rock is deposited equally in each region. However, once the rock is formed, differences in the climate cause erosion to occur differently. Suppose for example the region on the right side of this animation was exposed to more water. That would cause the rock to erode. If the region on the left side of the animation stayed rather dry, then the rock wouldn't erode at all. In the end then, eve ...
