• A deep ocean trench forms

What occurs when two oceanic crust plates converge?

• One plate keeps getting pushed down under the other plate as they continue to move together.

• The plates move away from each other, creating a new oceanic ridge.

• The plates slide past each other, causing earthquakes along the boundary.

• The plates collide and form a mountain range on the ocean floor.

What happens to the density of the new seafloor as it cools?

• It gets more dense the older it gets

• It becomes less dense over time

• It remains the same density

• It fluctuates randomly

What occurs at an oceanic-oceanic convergent boundary?

• old crust is recycled by subduction

• new crust is formed by volcanic activity

• tectonic plates move apart

• earthquakes are rare in this region

Features found at divergent boundaries include ________________.

• mid ocean ridges

• ocean trenches

• volcanic arcs

• transform faults

Crust is neither created nor destroyed at what type of boundary?

• Transform boundaries

• Convergent boundaries

• Divergent boundaries

• Subduction zones
