Exam 9: Earthquakes and Earths Interior

Would earthquakes of similar magnitudes in different regions of the Earth cause approximately the same levels of damage necessarily? In your explanation, consider both geologic and human- induced factors.

________have the highest velocities.

Which one of the following statements about the crust is NOT true?

P waves ___________ .

The ________core is probably solidified.

Which one of the following statements is correct?

Using the time- travel graph below, how long does it take a P wave to travel 2000 km?

The Richter magnitude of an earthquake is determined from the ________.

The elastic rebound theory for the origin of earthquakes was first proposed by________ following the ________earthquake.

__________is the layer of warm rock below the crust and uppermost mantle that readily deforms and flows plastically.

Which one of the following is TRUE regarding tsunamis?

The________ Magnitude is a measure of the total energy released. It does not directly measure the extent of building damage.

Most of our knowledge about Earth's interior comes from________ .

Which one of the following best characterizes tsunamis?

Approximately how much more energy is released in a 6.5 Moment Magnitude earthquake than in one with Mw of 5.5?

Since much of our knowledge of Earth's interior is inferred from the behavior of seismic waves and not actual samples, what are some of the assumptions that are made in order for our models to be correct? (Hint: Think of earth materials, physical and chemical parameters, etc.)

On a typical seismogram,________ will show the highest amplitudes.

The instrument that records earthquake events is termed a_______ _.

________is the cool, brittle, outer layer of Earth that includes the crust and uppermost mantle.

The upper mantle is very close in chemical and mineralogical composition to__________ .
