Correspondingly, how do scientists determine the age of the ocean floor?
Scientists can determine the age of the seafloor thanks to the changing magnetic field of our planet. As rocks crystallize from lava at the ridges, they literally record the magnetic field of the Earth at the time of their creation.
Also, what does the seafloor spreading suggest on the ocean floor age? The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earth's surface to fill in the empty void. In essence, oceanic plates are more susceptible to subduction as they get older.
Simply so, how are ocean basins formed?
Ocean Basin Features Plates can spread apart by moving away from each other. This creates gaps where hot molten rock, called magma, from the earth's mantle can rise up. When the magma seeps through the gaps, it solidifies as it cools, creating a new layer of ocean crust.
What are the stages of the ocean basin evolution?
There are some stages of ocean basin evolution. The evolution contains five stages which are embryonic stage, juvenile stage, mature stage, declining stage, terminal stage, mature stage, and continental collision.
