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

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

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

• 1. through iron and nickel, while S-waves cannot

• 1. through liquids, while S-waves cannot

Base your answer to the question on the photograph below, which shows an outcrop of sedimentary rock layers that have been tilted and slightly metamorphosed.

The tilted rock structure shown in the photograph is most likely the result of the

• 1. deposition of rock fragments on a mountain slope

• 2. reversal of past magnetic poles

• 2. passage of seismic waves

• 1. collision of crustal plates
