WebApr 1, 2010 · As the plates move, new sea floor can be created. The plates form three different kinds of boundaries: convergent, divergent, and transform. Convergent … WebSeafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading …
WebMay 20, 2024 · That is why earthquakes do not occur everywhere on Earth—they’re clustered around the boundaries of tectonic plates. Plate tectonics also explains the stripes of rock on the seafloor with alternating magnetic properties: As buoyant, molten rock rises up from deep within Earth, it emerges from the space between spreading tectonic plates and ... WebThe East Pacific Rise is a mid-ocean rise (termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), a divergent tectonic plate …
WebAs the two plates move apart from each other, which often occurs at a rate of several centimetres per year, molten rock wells up from the underlying mantle into the gap between the diverging plates and solidifies into new … WebNov 7, 2024 · Ocean trenches are steep depressions in the deepest parts of the ocean [where old ocean crust from one tectonic plate is pushed beneath another plate, raising mountains, causing earthquakes, and forming volcanoes on the seafloor and on land.
WebSeafloor Spreading The idea of continental drift circulated in scientific circles until World War II, when sounding gear produced new evidence of what the seafloor looked like. The …
WebSeafloor-spreading rates are much more rapid in the Pacific Ocean than in the Atlantic and Indian oceans. At spreading rates of about 15 cm (6 inches) per year, the entire crust beneath the Pacific Ocean (about 15,000 km … slv stromschiene 1 phase 3mWebOn each side of the ridge, sea floor moves from the ridge towards the deep-sea trenches, where it is subducted and recycled back into the mantle. A test of the hypothesis of sea-floor spreading was provided by studies of the Earth’s magnetism. Evidences Age of the sea floor: The age of the sea-floor also supports sea-floor spreading. slv stock price today stock price todayWebThe two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge. The figure shows the spreading ridge about 5 million years ago (a), about 2 to 3 million years ago (b) and nowadays (c).

This widening occurs as the new oceanic crust is created at mid-ocean ridges and spreads outwards. The process is driven by convection within the Earth’s mantle. Molten rock (magma) rises through the cover and solidifies on the ocean floor to form a new crust. slv stromschiene 1 phase
