Resumen del Recurso

Pregunta 1

Pregunta
What do Earthquakes Cause?
Respuesta
  • Shock waves, they travel on the surface and inside earth. We record them with Seismographs.
  • Ocean Trenches.

Pregunta 2

Pregunta
What Two Types of Waves are there.
Respuesta
  • P-Waves and S-Waves
  • D-waves and M-waves

Pregunta 3

Pregunta
Explain P-Waves
Respuesta
  • They go through Solids and Liquids. They are faster than S-Waves. They are Longitudinal.
  • They only travel through Solids. They are Slower. They Are Transverse.

Pregunta 4

Pregunta
Explain S-Waves
Respuesta
  • They only travel through Solids. They are Slower. They Are Transverse.
  • They go through Solids and Liquids. They are faster than S-Waves. They are Longitudinal.

Pregunta 5

Pregunta
What happens to waves when they reach different layers of earth?
Respuesta
  • They reflect, Sometimes
  • They go init.

Pregunta 6

Pregunta
Do waves Change Speed?
Respuesta
  • Yes, as the properties of the Mantle and Core change, it causes them to also change direction slightly - This is Refraction
  • Nope.

Pregunta 7

Pregunta
Is the speed Change of waves Gradual?
Respuesta
  • A lot of the time, it is, so it's got a curved path. But when the properties change suddenly, speed changes abruptly and so does Direction.
  • No its sudden.

Pregunta 8

Pregunta
What do P-waves tell us about The Mantle and Core.
Respuesta
  • P-Waves change direction abruptly about halfway down into earth, showing a sudden change in properties.
  • Nuffin.

Pregunta 9

Pregunta
S-waves are not detected in the core's shadow, what does this tell us?
Respuesta
  • That the Outer core is liquid because S waves only go through Solids
  • THat the Core is Gas.

Pregunta 10

Pregunta
P-waves travel slightly faster in the core, what does this show?
Respuesta
  • That the core is Solid.
  • That the core is Gas.

Pregunta 11

Pregunta
S-waves go through mantle, what does this show?
Respuesta
  • That the Mantle is solid.
  • That the Mantle is Liquid.
