• Convergent, Divergent, and Transform

What did Wegener name the supercontinent that existed 250 million years ago?

• Gondwana

• Laurasia

• Panthalassa

• Pangaea

What type of boundary may result in deep ocean trenches, volcanic islands, and volcanic mountains?

• Divergent

• Convergent

• Transform

• Both Convergent and Divergent

What force is responsible for the movement of plates on the asthenosphere?

• The rotation of the Earth

• Gravity

• Convection currents in the mantle

• Magnetism in the cores

At which plate boundary do only earthquakes occur (no other landforms created)?

• Convergent

• Divergent 

• Transform

The process by which molten material adds new oceanic crust to the ocean floor. At the same time, older strips of rock move outward from either side of the ridge

• mid-ocean ridge

• sea-floor spreading

• Mariana trench

• fault lines

A break or fracture in the ground that occurs when Earth's tectonic plates move or shift.

• convergent plate boundry

• mid-ocean ridge

• divergent plate boundry

• fault lines

The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary

• earthquake

• rift valley

• transformation

• subduction

What type of event will occur at this boundary?

• Earthquake

• Volcano Eruption

• Tornado

• Mountain Building

A divergent boundary occurs when plates ....
