Triple

Target class: volcanic fissure
Context triple: [Chinyero vent, instanceOf, volcanic fissure]

• A. volcanic rift zone
  A volcanic rift zone is a linear region of the Earth's crust where tectonic plates are pulling apart, allowing magma to rise and create fissures, vents, and often aligned volcanic eruptions.
• B. fissure system chosen
  A fissure system is a network of linear fractures or cracks in the Earth's crust through which magma, fluids, or gases can move and sometimes erupt at the surface.
• C. volcanic ridge
  A volcanic ridge is an elongated, elevated landform created by successive volcanic eruptions and lava flows that solidify along a linear zone, often associated with tectonic plate boundaries or rift zones.
• D. volcanic crater
  A volcanic crater is a roughly circular, bowl-shaped depression at the summit or flank of a volcano, formed by explosive eruptions or collapse around a volcanic vent.
• E. ignimbrite-filled valley
  An ignimbrite-filled valley is a landscape depression that has been infilled and partially reshaped by thick deposits of welded volcanic ash-flow tuffs from explosive eruptions.
• F. None of above.
