Dr. Mendoza and his team are studying two plates that are far apart from each other. However, these two plates used to be next to each other. What happened to the gap that was created by the plates moving apart?

• Sand and dirt filled in the gap.

• Soft, solid rock from underneath the plates rose and hardened, adding new solid rock.

• A new plate from underneath filled in the gap.

• Ocean water filled in the gap.

The plate boundary shown is ______________ . This means that _____ .

• Divergent; one plate will be pushed into the mantle and the other will experience uplift.

• Divergent; the plates will separate, and magma from the mantle will create new rock on the edges of the plates over time.

• Convergent; the plates will collide, and one plate will subduct into the mantle.

• Convergent; the plates will separate and water will fill the gap between them over time.
