Plate Tectonics Exam

What is the theory of plate tectonics?

• Earth's surface is made of rigid slabs of rock called plates that move with respect to each other.

• Earth's surface is a single solid piece that does not move.

• Earth's surface is made of liquid layers that flow freely.

• Earth's surface is made of gas layers that expand and contract.

What is the lithosphere?

• The solid, outermost layer of Earth made of crust and upper mantle.

• The liquid core of Earth.

• The gaseous atmosphere surrounding Earth.

• The molten lava beneath Earth's surface.

What is the asthenosphere?

• A hot, semi-plastic layer of Earth below the lithosphere.

• A cold, rigid layer of Earth's crust.

• A solid, metallic core of Earth.

• A gaseous layer above Earth's surface.

How do tectonic plates move?

• They move slowly, only 1–9 cm per year.

• They move rapidly, several meters per day.

• They remain stationary and do not move.

• They move in random directions at high speeds.
