Plate Tectonics Vocab

What is Pangea?

• Circular currents in the mantle.

• Boundary between two plates that are sliding past each other.

• A supercontinent containing all of Earth's land that existed about 225 million years ago.

• The process by which new oceanic lithosphere forms.

What is the process of Sea Floor Spreading?

• Sections of the Earth's crust that move due to convection currents.

• Areas where plates move toward each other and collide.

• The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.

• The theory that pieces of Earth's lithosphere are in constant motion.

What are Convection Currents?

• Boundary between two plates that are sliding past each other.

• Circular currents in the mantle caused by the magma being heated by the core of the Earth.

• Tectonic plates spreading apart, new crust being formed.

• A supercontinent containing all of Earth's land.

What are Tectonic Plates?

• Areas where plates move toward each other and collide.

• Circular currents in the mantle.

• The process by which new oceanic lithosphere forms.

• Sections of the Earth's crust that move due to convection currents.

What occurs at Convergent Plate Boundaries?

• Tectonic plates spreading apart, new crust being formed.

• Boundary between two plates that are sliding past each other.

• Areas where plates move toward each other and collide, causing uplift.

• Circular currents in the mantle.

What is a convergent plate boundary?

• Areas where plates move towards each other and collide, causing an uplift.

• Tectonic plates spreading apart, new crust being formed (ex. mid-ocean ridges, rift valley).

• Boundary between two plates that are sliding past each other.

What is a divergent plate boundary?

• Areas where plates move towards each other and collide, causing an uplift.

• Tectonic plates spreading apart, new crust being formed (ex. mid-ocean ridges, rift valley).

• Boundary between two plates that are sliding past each other.

What is a Transform plate boundary?

• Areas where plates move towards each other and collide, causing an uplift.

• Tectonic plates spreading apart, new crust being formed (ex. mid-ocean ridges, rift valley).

• Boundary between two plates that are sliding past each other.
