Pacific-Antarctic Ridge​

Antarctic

The Pacific-Antarctic Ridge is a mid-ocean ridge that runs in the southern Pacific and the adjacent southern ocean . The Pacific and Antarctic plates move apart , sometimes at speeds between 5.4 and 7.6 cm per year, in the eastern section, near the East Pacific Ridge , the value is even higher. As a result, magma flows in and the submarine mountains pile up.
