6th Plate Tectonics

An undersea mountain chain where new ocean floor is produced; a divergent plate boundary under the ocean:

• Mariana Trench
• Pacific Ring of Fire

• Mid-Ocean Ridge

• Mountain Range

The process by which molten material adds new oceanic crust to the ocean floor:

• Continental drift
• Plate tectonics
• Subduction
• Seafloor spreading

The process by which oceanic crust sinks beneath a deep ocean trench and then and back into the mantle at a convergent plate boundary:

• Erosion
• Expansion
• Sublimation
• Subduction
