Gibraltar Arc

Target entity: Gibraltar Arc
Context triple: [Mediterranean geodynamics, relatedTo, Gibraltar Arc]

• A. Alboran Ridge
  Alboran Ridge is a prominent submarine geological feature in the western Mediterranean Sea that separates the Alboran Basin from adjacent deep-water areas.
• B. Gibraltar sill
  The Gibraltar sill is the shallow submarine threshold at the Strait of Gibraltar that controls deep-water exchange between the Mediterranean Sea and the Atlantic Ocean.
• C. Calabrian Arc
  The Calabrian Arc is a geologically active subduction-arc system in the central Mediterranean, where the Ionian Sea plate is being forced beneath the Calabrian region of southern Italy, producing intense seismicity and volcanism.
• D. Azores–Gibraltar fracture zone
  The Azores–Gibraltar fracture zone is a major tectonic boundary in the North Atlantic that marks the complex transition between the Mid-Atlantic Ridge and the plate interactions around the western Mediterranean.
• E. Azores–Gibraltar region
  The Azores–Gibraltar region is a tectonically active area in the eastern North Atlantic where major plate boundaries interact between the Azores and the Strait of Gibraltar.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Gibraltar Arc
Target entity description: The Gibraltar Arc is a complex tectonic and orogenic belt at the western Mediterranean, where the interaction of the African and Eurasian plates has produced a distinctive arcuate mountain system and active geodynamic processes.
