The graph shows the different velocities of P-waves and S-waves through Earth's interior.
Which cross section best shows the inferred thickness of Earth's interior layers that cause these different velocities?
A.
B.
C.
D.
C.
What would be the best explanation as to why the S waves suddenly stop at the point they do?
A.
the S waves are not strong enough to go any further
B.
the S waves can only travel through solids, so there must be a liquid at that location.
C.
the P waves stop the S waves from going any further.
D.
The S waves can only move through liquids, so there must be a solid at that location.
