Pacific–North American plate boundary system

Target entity: Pacific–North American plate boundary system
Context triple: [Queen Charlotte Fault, partOf, Pacific–North American plate boundary system]

• A. North American plate boundary system
  The North American plate boundary system is the complex network of tectonic plate boundaries and associated fault zones that define the interactions and margins of the North American Plate with adjacent plates.
• B. Cascadia Subduction Zone
  The Cascadia Subduction Zone is a major convergent plate boundary off the Pacific Northwest coast of North America, capable of generating powerful megathrust earthquakes and tsunamis.
• C. Pacific margin of the Americas
  The Pacific margin of the Americas is the tectonically active western edge of North and South America, characterized by subduction zones, mountain-building, and frequent earthquakes and volcanism along the Pacific Ocean.
• D. Cocos–Nazca spreading center
  The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
• E. Nootka Fault
  Nootka Fault is a major transform fault off the coast of British Columbia that separates segments of the Explorer Plate and plays a key role in the tectonics of the Cascadia subduction zone.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
