Chapter 1 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 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.
