Alaska Subscriber. Answer: A triplane fracture extends through the transverse (growth plate), sagittal (epiphysis), and coronal (distal tibial metaphysis) planes of the distal tibia. It disrupts the tibial plafond intra-articularly.
Convergent Boundaries. Introduction. Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone.When two continental plates collide mountain ranges like the Himalayas form.Trenches form at subduction zones, USGS. Subduction zone. The subducting plate is being recycled as it begins to melt at about 100 kilometers.The water soaked oceanic plate forms molten rock that collects in magma chambers.ubduction zone.

oceanic-continental convergence. When an Oceanic and a Continental Plate converge the Oceanic Plate sinks underneath the Continental Plate. The area were the plate sinks into the Mantle is called a Subduction zone. Subduction Zones along an Oceanic-Continental boundary create a deep-sea trench.onvergent Boundary. In Plate Tectonics, a Convergent Boundary, also known as a destructive plate boundary because of Subduction. A Convergent Boundary is an actively deforming region where two or more tectonic plates or fragments of the Lithosphere move toward one another and collide.
