ppefmhEdGarstin1/4The diagrams below show the patterns of S waves and P waves after an earthquake.
  • This is due to the Earth's rotation.
  • This is due to the Earth's magnetic field.
  • This is due to the density changes in the Earth's interior?
Regions where S waves cannot be detected are called the S wave shadow zone.
  • S waves are transverse waves and cannot travel through liquids. This means that S waves cannot pass through the outer core (which is a liquid). As we can see from the diagram above.
  • S waves are longitudinal waves and cannot travel through liquids. This means that S waves cannot pass through the outer core (which is a liquid). As we can see from the diagram above.
  • S waves are magnetically charged waves and cannot travel through liquids. This means that S waves cannot pass through the outer core (which is a liquid). As we can see from the diagram above.
Regions where P waves cannot be detected are called the P wave shadow zone.
  • P waves travel faster in solids than in liquids. This means that when P waves enter the liquid outer core, they slow down. This causes them to change direction (refract). They also refract when they pass out of the outer core. This means that P waves do not pass into the P wave shadow zones.
  • P waves travel slower in solids than in liquids. This means that when P waves enter the liquid inner core, they slow down. This causes them to change direction (refract). They also refract when they pass out of the inner core. This means that P waves do not pass into the P wave shadow zones.
  • P waves travel faster in liquids than in solids. This means that when P waves enter the liquid outer core, they slow down. This causes them to change direction (refract). They also refract when they pass out of the outer core. This means that P waves do not pass into the P wave shadow zones.
  • Very faint P waves can sometimes be detected in the P wave shadow zone. This told scientists that the Earth must contain a solid inner core.
  • Very faint S waves can sometimes be detected in the P wave shadow zone. This told scientists that the Earth must contain a solid inner core.
