Plate Tectonics Vocab

What is the asthenosphere?

• The rigid upper layer of the Earth.

• A rigid section of Earth's crust that moves very slowly.

• A layer of the upper mantle in which rocks can deform like plastic.

• The layer of Earth between the crust and the core.

What typically forms at a collision zone?

• Earth's crust is divided into plates.

• New crust is created.

• High mountains often form.

• The mantle extends from the Earth's surface to the base of the crust.

What is a plate in terms of plate tectonics?

• The layer of Earth between the crust and the core.

• The rigid upper layer of the Earth.

• A boundary between plates that are moving away from each other.

• A rigid section of Earth's crust that moves very slowly.

What is the definition of plate tectonics?

• A boundary between plates that are sliding past one another.

• The movement of plates that make up Earth’s surface.

• An opening in Earth’s crust from which lava, gas, and ash erupt.

• A convergent boundary where one plate is sliding beneath another.

What happens at a subduction zone?

• Plates move in opposite directions along a fault.

• Lava, gas, and ash erupt from the Earth's crust.

• One plate slides beneath another plate.

• Material from the Earth's crust forms a mountain.
