North American plate boundary system

Target entity: North American plate boundary system
Context triple: [Explorer Plate, partOf, North American plate boundary system]

• A. North American Plate
  The North American Plate is a major tectonic plate that underlies most of North America, parts of the Atlantic Ocean, and surrounding regions, playing a key role in shaping the continent’s geology and seismic activity.
• B. North American Cordillera
  The North American Cordillera is the vast, complex chain of mountain ranges running along western North America from Alaska through Canada and the United States into Mexico, encompassing systems such as the Rockies and the Sierra Nevada.
• C. 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.
• D. Gorda Plate
  The Gorda Plate is a small tectonic plate off the coast of northern California that forms part of the complex plate boundary system between the Pacific and North American Plates.
• E. Rio Grande Rift
  The Rio Grande Rift is a major north–south trending continental rift zone in the southwestern United States that marks where the Earth's crust is being pulled apart, forming a series of basins and uplifted ranges.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: North American plate boundary system
Target entity description: 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.
