Question

because s - waves do not occur past 103° from the epicenter of an earthquake (s - wave shadow zone), we know that: select one: oa. s waves die out after traveling short distances ob. the earths core is hollow oc the outer core is solid od. the outer core is liquid

Explanation:

S - waves are shear waves and can only travel through solids. The absence of S - waves beyond 103° from an earthquake's epicenter indicates that the outer core, which they would need to pass through in that range, is liquid as S - waves cannot propagate through liquids.

Answer:

D. The outer core is liquid
