ESS Sec 10.2 Review

The theory that explains how large pieces of the lithosphere move.

• Plate tectonics
• Continental drift
• Sea-floor spreading
• Accretion

Solid, plastic layer of the mantle flows very slowly.

• Lithosphere
• Asthenosphere
• Crust
• Mantle

A boundary where two plates move away from each other.

• Transform 
• Convergent
• Divergent
• Subduction zone

A boundary where two plates are colliding.

• Subduction zone
• Transform
• Divergent
• Convergent

A boundary where two plates are sliding past each other horizontally.

• Transform
• Convergent
• Divergent
• Subduction zone

Cycle in which heated material rises and cooler material sinks.

• Density cell
• Convection cell
• Temperature cell
• Drag cell

Region along a plate boundary where one plate moves under another plate.

• Deep-ocean trench
• Subduction zone
• Mid-ocean ridge
• Rift

Outer layer of the Earth made up of the crust and the upper layer of the mantle.

• Asthenosphere
• Rock sphere
• Lithosphere
• Upper crust

The force exerted by the leading edge of a subducting plate.

• Slab pull
• Ridge push
• Drag
• Convection cell

What type(s) of crust can be on a tectonic plate?

• Neither oceanic or continental
• Both oceanic and continental
• Only oceanic
• Only continental
