Answer to Question 1

Oceanic crust is different than continental crust. The density of the entire Earth is 5.5 g/cm3 but typical mantle only has a density of 3.2 g/cm3.

Answer to Question 2

The P waves arrive first, then the S waves, then finally the surface waves. Wave velocities reflect compositional differences in materials.
