North American geology

North American geology encompasses the study of the continent's physical structure, including its mountains, valleys, and rock formations. It features ancient mountain ranges like the Rockies, formed by tectonic activity. The eastern part has the Appalachian Mountains, shaped by erosion over millions of years. The Great Plains consist of sedimentary rocks from ancient seas. Geologically active areas, like the West Coast, experience earthquakes and volcanic activity due to the Pacific Plate's movement. Overall, North America's geology reflects a complex history of shaping processes including plate tectonics, erosion, and sediment deposition.
