WebOther linear features that did not form in this way are highlighted by blue lines, (1) A pseudofault, the scar left by a migrating second-order offset of the ridge crest, (2) an abandoned segment of ridge crest (Cande et al., 1982), (3) a linear ridge formed by interactions between a mid-ocean ridge segment and excess melt delivered from a … WebA theoretical model of the formation of magnetic striping. New oceanic crust forming continuously at the crest of the mid-ocean ridge cools and becomes increasingly older as it moves away from the ridge crest with seafloor spreading (see text): a. the spreading ridge about 5 million years ago; b. about 2 to 3 million years ago; and c. present-day.
Why are the mid ocean ridges elevated? [Solved!]
http://worldlandforms.com/landforms/mid-ocean-ridge/ A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. … Meer weergeven The mid-ocean ridges of the world are connected and form the Ocean Ridge, a single global mid-oceanic ridge system that is part of every ocean, making it the longest mountain range in the world. The continuous … Meer weergeven Increased rates of seafloor spreading (i.e. the rate of expansion of the mid-ocean ridge) have caused the global (eustatic) sea level to rise over very long timescales (millions of … Meer weergeven Discovery The first indications that a ridge bisects the Atlantic Ocean basin came from the results of the British Meer weergeven Morphology At the spreading center on a mid-ocean ridge, the depth of the seafloor is approximately … Meer weergeven The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. Two processes, ridge-push and slab pull, are thought to be responsible for spreading at mid-ocean ridges. Ridge push refers … Meer weergeven Seafloor spreading on mid-ocean ridges is a global scale ion-exchange system.

This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading.
