Question

which layers can s-waves go through
A. inner core, mantle, and crust
B. outer core, inner core, and crust
C. inner core, outer core, and mantle
D. outer core, mantle, and crust

Answer 1

S-waves (shear waves) cannot travel through liquids, so they cannot pass through the outer core, which is liquid. They can travel through the inner core, mantle, and crust, which are solid. Therefore, the correct answer is:

**A. inner core, mantle, and crust**.
