This set of lecture notes covers several topics relating to the earth's interior. Seismic waves and the earth's internal structure are discussed. Several mechanisms for the origin of magma are offered. These lecture notes are in outline form with definitions and instructive diagrams. This resource is part of the Teaching Petrology collection.

Part of the Cutting Edge collection. The NAGT/DLESE On the Cutting Edge project helps geoscience faculty stay up-to-date with both geoscience research and teaching methods.
