Part of mantle where lithosphere floats

• Crust
• Core
• Asthenosphere
• Atmosphere

One large landmass

• North America
• Pangea

Heat transfers within the Earth 

• Conduction
• Convection Current
• Ocean Current
• Radiation

Addition of new sea floor

• Subduction
• Sea Floor Spreading
• Sea Floor subduction
• Convergent

Plates sliding past each other in opposite directions

• Convergent

• Transform 

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries
