Why do seismic waves travel through the earth at different rates?

• It takes time to move through land

• Some move through oceans

• The composition of the Earth's core; some waves travel through solids and liquids, others only liquids

• They all travel at the same rate.

These waves only go through solids....

• P waves

• S waves
