WebA mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

What is a Runnel on a beach? Webformed by lava that is very fluid and flows quickly (high effusion rate), while pillow lavas are bulbous mounds formed by slow-flowing lava (low effusion rate). (6) Do volcanoes at mid-ocean ridges and sub-duction zones erupt explosively? Volcanoes at subduction zones often erupt explosively; volcanoes at mid-ocean ridges usually do not. 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.
