Chapter 12-Earth’s Interior Basic Cosiderations o The center of the Earth is about 6400 km below us…the deepest well is ~10 km o Heat inside the Earth drives the core’s geodynamo and the mantle’s convection o Earth’s Interior is explored by using information from seismic waves and their passage through the body of the Earth Exploring the interior with seismic waves o Seismic waves can be used to infer structure and composition of Earth and transitions marking boundaries P and S waves travel through specific materials 1. Recall: P waves=compressional (faster); S waves=shear (slower) 2. P waves travel through solids, liquids, and gases 3. S waves travel only through solids Seismic velocity depend on material (denser material moves faster)
