6.2/6.3 Interactions of Plates Quiz

Match the term to its description:

• Mid-Ocean Ridge

• the process of older rock being pushed away from a mid-ocean ridge towards the continents

• Seafloor Spreading

• a geologic feature formed from the convergence of two oceanic plates where cooling lava eventually forms a group of islands

• Subduction Zone

• a region along a convergent plate boundary where one plate moves underneath another

• Island Arc

• a deep underwater valley formed by the subduction of one tectonic plate beneath another

• Oceanic Trench

• an undersea mountain range where new crust in generated
