Plate Tectonics and Earthquakes Class Review

Sea-floor spreading at mid-ocean ridges is an example of this type of plate boundary movement.

• Convergent

• Divergent

• Transform

The point on the surface directly above the point at which the earthquake occurs.

• Focus

• Epicenter

• Seismic waves

• Surface waves

The breaks in Earth's crust where rocks can move is called

• focus

• fault

• epicenter

• plates

the idea that continents move around on Earth's surface.

• plate tectonics
• earthquake
• continental drift
• volcanic eruption

When an oceanic plate collides with a continental plate, the oceanic plate is usually subducted because

• continental plates move faster than oceanic plates

• oceanic crust is denser and thinner than continental crust

• oceanic crust is denser and thicker than continental crust

• continental crust is denser and thinner than oceanic crust

What order to the 3 types of seismic waves arrive at a seismometer?

• surface waves, P waves, S waves

• P waves, surface waves, S waves

• P waves, S waves, surface waves

• S waves, P waves, surface waves

This area around the Pacific plate is the location of many earthquakes and volcanic activity.

• San Andreas fault

• Hawaii

• Ring of Fire

When 2 plates slip past each other, it happens at this plate boundary.

• Convergent

• Divergent

• Transform

Deep ocean trenches can form at this plate boundary.

• Convergent

• Divergent

• Transform

What is a rating of an earthquake's magnitude based on the size of the earthquake's seismic waves?

• seismograph
• seismogram
• Richter scale
