Plate Motion

Which statement best describes Earth's outer layer?

• 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 sand, soft rock and water.

• 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.

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.
