Earth's Interior

Explore Earth's internal structure in this 49-minute lecture covering the planet's layered composition, seismic wave behavior, and methods for probing the interior. Learn about Earth's core, mantle convection, geothermal gradients, and gravity anomalies. Discover how seismic tomography reveals the three-dimensional structure of our planet and gain insights into determining the depth of the Moho discontinuity and the significance of P and S wave shadow zones.
