Plates on the Move

The boundary between the Pacific Plate and the Australian Plate is a transform boundary.  What event is likely to occur at this boundary?

• Mountain formation
• Earthquakes
• Hurricanes
• Volcanic eruptions

The San Andreas Fault in California is a result of movement between the Pacific and the N. American plates. Name of this plate movement is _______?

• Convergent
• Divergent
• Transform
• Subduction

What is subduction?

• It's when plates collide and form mountains.
• It's when plates pull apart and make new crust.
• It's when plates slide past each other, destroying the crust.
• It's when plates collide and the denser sinks below the less dense plate.

Which layer is broken into pieces called plates?

• Asthenosphere
• Crust
• Lithosphere
• Mantle

Which layer is "squishy" allowing the plates to float on top of it?

• mantle
• Atmosphere
• Lithosphere
• Mesosphere

What causes the plates to move?

• Ocean Tides
• Earthquakes
• Subduction of plates converging
• Convection currents within the mantle

Where do most geological events happen?

• In the Pacific Ocean
• On larger continents
• Along the plate boundaries
• At the North and South Poles

Which of the following geologic events would most likely occur where two continental plates converge?

• Tsunami
• Earthquake
• Mountain formation
• Trench formation

Where tectonic plates pull away from each other, which of the following geologic land forms is most likely to form?

• Ridge
• Plateau
• Mountain
• Beach

What land form will most likely occur at a divergent plate boundary?

• The plates will form a mountain chain 
• One plate will subduct under the other 
• The plates will create a mid ocean ridge 
• A fault line will form, and earthquakes will result
