What do scientists study by analyzing how seismic waves travel through the earth?

• The weather patterns

• The atmospheric pressure

• The internal structure of the earth

• The ocean currents

What happens to seismic waves when they reach a boundary between two different mediums?

• They change color

• They are refracted or reflected

• They are absorbed

• They disappear

Why can't S waves travel through the liquid outer core?

• Because they change direction

• Because they are reflected

• Because they are refracted

• Because they are absorbed

What was one of the main clues that led to the discovery of the liquid outer core?

• The change in direction of S waves

• The change in direction of P waves

• The disappearance of S waves

• The disappearance of P waves

What happend to P waves when they travel through the liquid outer core?

• They are reflected

• Because they are refracted

What natural event allows scientists to study seismic waves?
