What is a Transform Boundary?

• A boundary where a denser plate is pushed beneath a less dense plate

Where does Subduction typically occur?

• At the Mid-Atlantic Ridge

• At continental to oceanic boundaries and oceanic to oceanic boundaries

• At transform boundaries

• On topographic maps

What type of boundary involves plates moving past each other?

• Subduction boundary

• Transform boundary

What happens to a denser plate during Subduction?

• It moves past another plate

• It is pushed downward beneath a less dense plate

• It forms a parallel pattern

• It creates a topographic map
