Question

Which statement supports the claim that the outer core of Earth is liquid? Choose the correct answer.

Answer Choices:
P-waves do not pass through the outer core.

S-waves do not pass through the outer core.

P-waves travel faster when they enter the outer core.

S-waves pass through the outer core and are refracted.

Answer 1

S-waves do not pass through the outer core.

Step-by-step explanation:

S - waves do no pass through the outer core and this suggests that this part of the earth's interior is liquid.

S - waves are secondary waves or shear waves.

They do not pass through fluids which are liquids and gases due to their properties. Unlike P- waves, they are cut off where fluids are present.

Therefore, on studying a seismic wave that permeates through the earth, there is an attenuation of S-waves in the core mantle boundary.
