How are oceanic ridges created
WebThe oceanic plates are the ones that make up the sea floor. The main difference between oceanic plates and continental plates is the type of crust found on each plate. Oceanic crust and continental crust are made out of different kinds of rock. The continental crust contains a lot of granite, which is an igneous rock. Web11 de jan. de 2024 · Divergent plate boundaries in the ocean create mid-ocean ridges. This is where new seafloor is created by upwelling magma. Divergent plate boundaries rift a continent apart. Eventually a new ocean will form between the two continents. Iceland is a location where we can see a mid-ocean ridge above sea level. Review

WebA 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. WebAnswer: A 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 …
WebIf both plates are oceanic, as in the western Pacific Ocean, the volcanoes form a curved line of islands, known as an island arc, that is parallel to the trench, as in the case of the Mariana Islands and the adjacent Mariana Trench. If one plate is continental, the volcanoes form inland, as they do in the Andes of western South America. WebMid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading …
