• Earth's outer layer is made up of a soft solid material.

• Earth's outer layer is made up of hard, solid rock.

• Earth's outer layer is a combination of hard, solid rock and a soft, solid material.

• Earth's outer layer is made up of hard, solid rock or water; it depends on where you go.

The team is drilling underground at sites 1 and 2. Where will the team find hard, solid rock?

• They will find hard, solid rock below site 1. At site 2, they will find water and sand.

• They will find hard, solid rock below site 2. At site 1, they will find plants and soil.

• They will find hard, solid rock below both sites.

• They will find hard solid rock at neither of these sites; they will find water below both of them.

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.

"Converge" means...

• To drift apart

• To move towards each other

• To slip by each other

• To stop

"Diverge" means...

• To move in different directions

• To move towards each other

• To slip past something

• To stop

The plate boundary shown in the image is a ______ boundary because...

• Convergent; the plates are moving away from each other.

• Convergent; the plates are moving towards each other.

• Divergent; the plates are moving towards each other.

• Divergent; the plates are moving away from each other.

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.
