Plate Boundaries and Layers of the Earth

What type of plate boundary causes sea floor spreading?

• convergent
• divergent
• transform
• compression

The stress caused by a transform plate boundary is

• compression
• tension
• shearing
• subduction

What stress is associated with a convergent plate boundary?

• compression
• tension
• shearing
• sea floor spreading

Where is new crust being formed?

• convergent
• divergent
• transform
• shearing

What is most likely to occur at a transform plate boundary?

• volcanoes
• mountain building
• earthquakes
• blizzards

Volcanoes occur at

• convergent plate boundaries
• hot spots 
• divergent plate boundaries
• all of these

Plate movement is cause by

• conduction currents in the crust
• convection currents in the mantle
• volcanoes
• earthquakes

The super continent that existed millions of years ago is called

• Wegener
• Pangea
• Jurassic World
• Eurasia

What type of plate boundary is pictured

• convergent
• divergent
• tranform
• tension

Oceanic crust is more dense than continental crust.  At a convergent plate boundary between oceanic crust and continental crust which crust is subducted?

• oceanic crust will go under the continental crust
• continental crust will go under the oceanic crust
• it depends on the speed the plate is moving
• there is no way to determine which plate will be subducted
