Lesson One, "Introduction to Geology," presents the basic terms of geology, the diversity of the earth's surface, the planet's internal structure, and the historical developments which help explain oceanic and continental formation.
Lesson Two, "Mountains, Volcanoes, and Earthquakes," demonstrates the dynamics of the plate tectonics theory. Concepts such as folding and buckling, subduction, volcanism, undersea mountains, and earthquakes are all explored in this video.
