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.

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.
Identify each type of convergent plate boundary. Since oceanic plates are denser than the continental plates, they will subduct to great depths when they converge with continental plates. When two oceanic plates converge, the denser of the two will subduct; whereas when two continental plates converge, neither will subduct. Therefore, the resulting geologic feature depends on the types of plates that converge. Depending on the type of plate convergence, different features could result.
