Royce and Marla...seismic review question answers

1.  P and  S waves interior waves.   P--longitudinal, S transverse

Raleigh is a surface wave---rolling action on the transverse wave

Love is a suface wave that slides parallel to the surface.


2.  P penatrates through all layers of the earth.  Refracting at various layers based on density and elascitiy of the medium.

S penatrate only mantel.  Reflecting or being absorbed by the outer core.  So there is a shadow portion of the earth that will not observe the S waves

Raleigh and Love are both surface waves.  So only felt on the surface but propagation is still governed by density and elascitiy of crust and surface features.
