Physics: Seismic Waves

Question 1 of 11

1

What do Earthquakes Cause?

Select one of the following:

  • Shock waves, they travel on the surface and inside earth. We record them with Seismographs.

  • Ocean Trenches.

Explanation

Question 2 of 11

1

What Two Types of Waves are there.

Select one of the following:

  • P-Waves and S-Waves

  • D-waves and M-waves

Explanation

Question 3 of 11

1

Explain P-Waves

Select one of the following:

  • 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.

Explanation

Question 4 of 11

1

Explain S-Waves

Select one of the following:

  • 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.

Explanation

Question 5 of 11

1

What happens to waves when they reach different layers of earth?

Select one of the following:

  • They reflect, Sometimes

  • They go init.

Explanation

Question 6 of 11

1

Do waves Change Speed?

Select one of the following:

  • Yes, as the properties of the Mantle and Core change, it causes them to also change direction slightly - This is Refraction

  • Nope.

Explanation

Question 7 of 11

1

Is the speed Change of waves Gradual?

Select one of the following:

  • 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.

Explanation

Question 8 of 11

1

What do P-waves tell us about The Mantle and Core.

Select one of the following:

  • P-Waves change direction abruptly about halfway down into earth, showing a sudden change in properties.

  • Nuffin.

Explanation

Question 9 of 11

1

S-waves are not detected in the core's shadow, what does this tell us?

Select one of the following:

  • That the Outer core is liquid because S waves only go through Solids

  • THat the Core is Gas.

Explanation

Question 10 of 11

1

P-waves travel slightly faster in the core, what does this show?

Select one of the following:

  • That the core is Solid.

  • That the core is Gas.

Explanation

Question 11 of 11

1

S-waves go through mantle, what does this show?

Select one of the following:

  • That the Mantle is solid.

  • That the Mantle is Liquid.
