MULTIPLE CHOICE QUESTION

absorbed by Earth’s outer core

transmitted only through liquids

weak and detected only at nearby locations

not produced by this earthquake

Which evidence recorded at seismic stations following an earthquake supports the inference that Earth’s interior changes from solid rock to molten iron and nickel at the mantle-core boundary?

P-waves arrive earlier than S-waves.

P-waves and S-waves are both recorded at all stations.

Only S-waves are recorded at all stations.

Only P-waves were recorded at seismic station C because P-waves travel

only through Earth’s interior, and S-waves travel only on Earth’s surface

fast enough to penetrate the core, and S-waves travel too slowly

through iron and nickel, while S-waves cannot

through liquids, while S-waves cannot
