WebApr 15, 2024 · Where does the ocean floor form? As plates converge, one plate may move under the other causing earthquakes, forming volcanoes, or creating deep ocean trenches. Where plates diverge from each other, molten magma flows upward between the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean … WebSeafloor spreading is the process by which new oceanic lithosphere forms at mid-ocean ridges. As tectonic plates move away from each other, magma rises from Earth’s interior. Where does new oceanic crust form quizlet? New oceanic crust is formed when the seafloor spreads as hot molten rock (magma) wells up into the rifts of the mid ocean ridge.
WebThe first such process is a downslope movement of sediments by mass wasting, a set of gravity-deposition events, including submarine landslides, slumps, debris flows, and high-velocity sediment-laden density flows known as turbidity currents. Several phenomena may initiate gravity events. north bedford drive beverly hills josh flaggWebThese surveys revealed a series of invisible magnetic “stripes” of normal and reversed polarity in the sea floor, like that shown in the figure below.
