Plate Tectonics

What are tectonic plates?

• Large pieces of Earth's crust that move

• Small rocks on the Earth's surface

• Rivers and lakes

• Clouds in the sky

Which layer of the Earth do tectonic plates form?

• Core

• Mantle

• Lithosphere

• Ocean

What is the Earth's crust?

• The center of the Earth

• The outermost layer of the Earth

• A kind of weather

• A type of plant

Where do tectonic plates meet?

• Deserts

• Mountain tops

• Plate boundaries

• River banks

What does the plate tectonics theory explain?

• How animals live

• How planets orbit the sun

• How tectonic plates move and shape the Earth

• How the weather changes

What is continental drift?

• Erosion by rivers

• Changes in the weather

• Movement of continents over time

• Formation of mountains

What is the lithosphere?

• The atmosphere

• The solid outer layer of the Earth

• The sun

• The ocean

What is the asthenosphere?

• A solid, rigid layer

• A plastic-like layer beneath the lithosphere

• A type of rock

• A mountain range

What happens at convergent boundaries?

• Plates move apart

• Plates slide past each other

• Plates move toward each other and collide

• Plates stay still

What are transform boundaries?

• Boundaries where plates move away from each other

• Boundaries where plates collide

• Boundaries where plates slide past each other

• Boundaries that do not exist
