WebFigure 4.5.3 Mechanism for divergent plate boundaries. The region in the outlined rectangle represent the mid-ocean ridge (Steven Earle, “Physical Geology”). or series of mantle plumes. The buoyancy of the mantle plume material creates a dome within the crust, causing it to fracture.
WebOceanic crust is thin (~6 km thick) and dense (about 3.3 g/cm 3), consisting of basalt, gabbro, and peridotite. Consequently, most oceanic crust is subducted easily at an oceanic trench. In contrast, continental crust is thick (~45 km thick) and buoyant, composed mostly of granitic rocks (average density about 2.5 g/cm 3). men\u0027s short sleeve silk button down shirtsmen\u0027s short sleeve sport shirts with pocketsWebConvergent boundaries, where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental.
