Earth Layers and Seismic Waves

How can you accurately represent the different layers of Earth's interior?

• By drawing a flat map of the Earth's surface

• By showing a cross-section of the Earth with labeled layers

• By listing the elements found on the Earth's surface

• By measuring the depth of the oceans

Which type of seismic waves can travel through all states of matter?

• S-waves

• P-waves

• Surface waves

• Love waves

Which type of seismic waves can only travel through solid matter?

• P-waves

• S-waves

• Rayleigh waves

• Tsunami waves

S waves cannot travel past the inner layers of the Earth, what does this suggest about Earth's interior?

• The innermost layers of the earth are too thick for S waves to travel through

• Some of the inner layers of the Earth must be liquid

• The innermost layers of the Earth must be solid

• The outer layers of the Earth must be liquid
