Earthquake and Volcano Concepts

This video introduces Chapter 2 of the geology exam review, focusing on key definitions, geological concepts, earthquakes, and volcanoes. It covers the study of geology, transition zones, and core-mantle boundaries. The video also explains lithosphere, Pangaea, mountain formations, and the differences between volcanic and dome mountains. Earthquake-related topics include tectonic earthquakes, tremors, aftershocks, and seismology. The video further explores volcanoes, types of lava, pyroclastic flow, and calderas. Finally, it discusses the identification of elements, faults, and types of earthquake waves.
