Lecture 9: Inside the Earth
What is the interior structure of the Earth and how does it drive the Earth's magnetic and geologic activity? We will review our current knowledge of the interior of the Earth, how we measure it using Seismology, the origins of the Earth's magnetic field, and discuss the workings of plate tectonics. the Earth is a dynamic, geologically active world, which has interesting implications later for understanding the past and future history of life on Earth. Recorded live on 2009 Oct 5 in Room 1005 Smith Laboratory on the Columbus campus of The Ohio State University.
