When two oceanic plates collide, the older denser plate subducts. The results of this tectonic collision are similar to those involving oceanic and continental plates. A deep trench is formed on the seafloor. As the oceanic crust sinks, a deep oceanic trench, or valley, is formed at the edge A subduction zone is also generated when two oceanic plates collide — the.
When two oceanic plates collide one oceanic plate is eventually subducted The magma that forms is andesitic in composition and begins to form when the. When two oceanic plates converge, the denser plate will subduct under the plate that is less dense, creating a deep sea trench at the point of subduction. As the subducted plate goes deeper into the mantle, the mantle material above it starts to melt to become magma. Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines If two tectonic plates collide, they form a convergent plate boundary.
A convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density. Instead, the.
