Exam 8: Earthquakes and Earths Interior

The ________ core is probably solidified.

________ have the highest velocities.

P waves ________.

Label the focus and epicenter on the diagram below.

What instrument is used to record earthquake vibrations?

________ is the maximum possible damage designation on the Mercalli scale.

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.)

Oceanic crust is mainly basaltic in composition; the mantle is more like the igneous rock peridotite in chemical composition.

The epicenter of an earthquake is on the surface of the Earth directly above the focus.

Continental crust is generally thicker than oceanic crust.

Overall, this type of seismic wave is the most destructive.

________ is the name of the earthquake-magnitude scale based on the amount of seismic energy released during the event.

________ is another name commonly used by scientists to denote seismic sea waves induced by earthquakes.

Which one of the following is true regarding tsunamis?
