Can someone me with this science question? explain why earthquakes provide indirect evidence about the layers of earth? use complete sentences to write your answer. (will mark brainliest if correct)

ANSWER:

Earthquakes create S and P waves. The P waves are quick and of a larger frequency than S waves. P waves arrive at a point first and can go through liquid whereas S waves reach after and they lose quite a bit of their energy while passing liquid media. This is on the grounds that S-waves are shear waves and require inelastic or inflexible media for transmission.

EXPLANATION:

During a quake, there is generally a shadow zone (where there isn't any destruction since S-waves didn't reach) framed right over the focal point of the quake. This is because of the fact that the S-waves were not able to travel through the inner core of the liquid of the earth before arriving at the surface. Just P-waves are enlisted in this shadow zone.Thus, earthquakes provide indirect evidence about the layers of Earth
