Question

Select the correct location on the image.

Answer 1

Answer:

D.

Explanation:

The refraction of P-waves in the inner core suggests that this layer is solid. P waves are able to travel through both liquids and solids, albeit not uniformly. Inge Lehmann observed this and predicted that the inner core of the Earth  must be solid.

The outer core is known to be liquid, or at  least partially liquid because S-waves cannot travel through that layer.
