Seismic Waves

• Primary waves

  • Fastest
  • Push and pull waves
  • Longitudinal
  • Travel through water and solids
• Secondary waves

  • Side to side waves
  • Transverse waves
  • Slower than P waves
  • Only travel through solids
• P waves are refracted when they enter and leave the outer core
• Secondary waves cannot travel through the outer core so they cant reach the shadow zone
