Lecture 18 Earth's Interior Imaging Earth's interior Propagation of Seismic waves Major layers of the interior: crust, mantle, core Dynamics of the Earth's.
Conclusions… Challenge: 1)Seismic waves are affected by variations in temperature, pressure, composition, mineralogy, structure (layering, scales and distribution.
