Seismic Waves Quiz

The speed of seismic waves and the paths they take give geologists clues about Earth's internal structure.

• True
• False

List the layers of the Earth in order from outermost to innermost.

• inner core, outer core, mantle, crust
• crust, mantle, inner core, outer core
• crust, mantle, outer core, inner core
• inner core, outer core, crust, mantle

What are the 2 types of Surface Waves?

• Love & Rayleigh
• Love & Hate

• Spring & Neap

Which layer of Earth is a solid ball of metal?

• crust
• mantle
• outer core
• inner core

Which layer is mostly melted rock?

• crust
• mantle
• outer core
• inner core

How do scientist know that the outer core is made up of liquid metal?

• Seismographic data shows that P-waves don't travel through the outer core.
• Seismographic data shows that S-waves don't travel through the outer core.
• Seismographic data shows that S-waves don't travel through the mantle.
• Seismographic data shows that P-waves & S-waves don't travel through the outer core.

Body waves radiate outward from the

• earthquake.
• epicenter.
• focus.
• inner core.

Which type of seismic wave causes the most damage?

• P-waves
• S-waves
• Surface waves
• Body waves

Directly above the focus point (on the surface) is called an

• fault
• fault line
• epicenter
• focus

What are seismic waves?

• Vibrations that travel through Earth carrying water.
• Vibrations that travel outward from the epicenter.
• Vibrations that do not travel and carry nothing.
• Vibrations that travel through Earth carrying energy from an earthquake.
