WebGeology Chapter 1 2 3. What are the basic differences between the disciplines of physical and historical geology? B) Historical geology involves the study of rock strata, fossils, and geologic events, utilizing the geologic time scale as a reference; physical geology includes the study of how rocks form and of how erosion shapes the land surface. Adjacent plates pull apart, such as at the Mid-Atlantic Ridge, which separates the North and South America Pates from the Eurasia and Africa Plates. This pulling apart causes "seafloor spreading" as new material from the underlying less rigid layer, or "asthenosphere," fills the cracks and adds to these oceanic plates. … See more Two plates move towards one another and one is dragged down (or "subducted") beneath the other. Convergent plate boundaries are also … See more One plate slides horizontally past another. The best-known example is the earthquake-prone San Andreas Fault Zone of California, which marks the boundary between … See more
