Mid ocean ridge how does it form
WebThis evidence led early marine geologists to deduce that the mid-ocean ridges were formed by seafloor volcanoes. When these volcanoes erupted, they spewed out lava that cooled and solidified to become new seafloor. It was soon discovered that when this lava cooled, magnetic particles within it aligned with Earth’s magnetic field. Web13 feb. 2024 · Iron Source. One of the importance of mid ocean ridges is that they are estimated to produce iron that makes up about 25 to 75 percent of global ocean iron stocks. It also appears that the iron produced by the mid ocean ridge have a much longer lifetime and can be exported from the ridge until up to 4,000 km away from its initial place.
