4 cards from this section. Quick, good the night before a test.
What is the outermost layer of the Earth called?
Think about the surface we walk on.
What type of wave cannot travel through liquids?
Remember, 'S' for solid.
Which layer of the Earth is in a liquid state?
Think about the properties of metals at high temperature.
True or false: S-waves can travel through liquids.
Remember what the 'S' stands for.
An earthquake occurs at a focus of 15 km below the surface. If seismic stations detect P-waves first at 5 seconds and S-waves afterwards at 10 seconds, calculate the time difference in travel and interpret what this tells us about the Earth’s layers.
Consider speeds: P-waves travel faster than S-waves.
Explain how gravity anomalies can indicate the presence of different types of materials in the Earth's crust and mantle.
Think about the principles of density and gravitational pull.
