The Great Falls of the Potomac were formed by the Potomac River cutting through the hard metamorphic rocks of the Appalachian Mountains, creating steep cliffs. The falls of Yosemite Valley were shaped by glacial activity during the last Ice Age, which carved out the valley and left behind dramatic granite cliffs and waterfalls. Similarly, the falls of the Yellowstone River were influenced by volcanic activity and glacial erosion, resulting in rugged terrain and dramatic drops. In all cases, a combination of geological processes, including erosion and glaciation, played a significant role in their formation.
