F.) Convergent boundaries: where two plates are colliding.
The denser plate is subducted underneath the less dense plate. The plate being forced under is eventually melted and destroyed. Island arcs and oceanic trenches occur when both of the plates are made of oceanic crust.
G) When two oceanic plates collide one oceanic plate is eventually subducted under ... is now less dense than the surrounding material so it rises through the crust .
H) Ocean-Continent Collisions As the oceanic plate is subducted sediment is scraped off to form an acretionary wedge at the point of collision between the two plates. When the oceanic plate is subducted due to partial melting of the asthenosphere magma with an andesitic composition is formed.
