Plate Tectonics & Earthquake Review

These seismic waves arrive first to signal an earthquake and can damage buildings.

• p-waves
• s-waves
• surface waves
• z-waves

These seismic waves arrive second and can shake the ground violently.

• p-waves
• s-waves
• surface waves
• z-waves

A sudden release of energy from plate movement creating shaking and trembling is known as:

• seismic wave
• earthquake
• focus
• epicenter

The point on the surface directly above the focus:

• earthquake
• seismic waves
• seismographic station
• epicenter

This word describes the intensity of the earthquake:

• seismograph

• magnitude

• focus

• epicenter

A break in the rock of the crust where rock surfaces slip past each other; usually occur along plate boundaries:

• focus
• epicenter
• fold
• fault

Where is the point at which the first movement occurs during an earthquake?

• Epicenter
• Focus
• Fault
• Plate

What is an instrument that detects and records waves produced by earthquakes?

• Epicenter

• Fault

• Seismogram

• Seismograph

What is a smaller earthquake that follows a larger earthquake?

• Aftershock
• Liquefaction
• Seismic Gap
• Tsunami

The outside layer of the earth is called ______________________.

• core
• crust
• mantle
• outer core
