Plate Tectonics

A ______ is a section of the lithosphere that slowly moves over the asthenosphere, carrying large slabs of continental and oceanic crust.

• wedge
• plate
• chunk
• fault

What is an undersea mountain chain where new ocean floor is produced?

• Rift valley
• Deep-ocean trench
• Mid-ocean ridge
• Transform bounda

A plate boundary where two plates move away from each other is called

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

A Plate Boundary where two plates move toward each other is called

• Convergent Boundary
• Divergent Boundary
• Transform Boundary
• Subduction

Convergent Plate Movement can create

• Rifts
• Mountains
• Ocean Ridges
• Radiation

_______________ Currents within the mantle cause the earth's plates to move and shift s molten material rises and falls due to density and gravity

• Convection
• Radiation
• Conduction
• Wind

Divergent Plate movement can create

• Convection Currents
• Conduction
• Mountains
• Rifts and ocean ridges

This boundary is described as two plates moving past eachother ALONG THE EDGES horizontally.  These boundaries will get stuck or lock against eachother causing earthquakes when they slip and release.

• Convergent, Subduction Zone
• Transform 

Mid Ocean Ridge Formation  is created at this type of  boundary.

• Divergent
