Question

The P-wave shadow zone is largely the result of...

a)Reflection of P waves from the inner core-outer core boundary
b)Lower P-wave velocities in the mantle than in the crust
c)Refraction of P waves crossing the mantle-core boundary
d)P waves not being able to pass through the outer core

Answer 1

C. Refraction of P waves crossing the mantle-core boundary.

Step-by-step explanation:

The P-wave shadow zone is largely the result of refraction of P waves crossing the mantle-core boundary.
