In the fourth episode, Professor Lisa Mcneill talks about the formation of new oceans, the development of plate tectonics, and her experience with marine expeditions. You will learn how scientists detect the expansion of oceanic crust and what life is like aboard a research vessel. We'll discover how scientists obtain information about our planet's past from deep-sea cores, why it's difficult to predict earthquakes, and how the tsunami early warning system works.
