Web7 de jul. de 2024 · Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones —that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity. WebDivergent Plate Boundaries: Divergent plate boundaries are where seafloor spreading occurs, producing new oceanic crust. Material from mantle intruded into fractures as plates are move apart. New oceanic crust is made, so this type of boundary is said to be “constructive.” Upper crust of oceanic plate is made of basalt (aphanitic mafic rock)
