Feb 15, 2024 · The meaning of MID-OCEAN RIDGE is an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.
The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).
The oceanic ridge system is the largest feature of the Earth’s surface after the continents and the ocean basins themselves; it is explained by the theory of plate tectonics as a boundary between diverging plates where molten rock is brought up from deep beneath the Earth’s crust.
Definition. Mid-ocean ridge (MOR) ophiolites represent oceanic lithosphere formed in the sea-floor spreading centers of ocean basin (Fig. 2; Pearce et al., 1984). The overall mechanism by which ophiolites are produced is reasonably well understood, although details continue to be controversial.
Oceanic ridges are the topographic expression of linear or curvilinear zones along which the Earth's oceanic crust is created or modified. A glance at any detailed bathymetric chart ( Fig. 1) reveals that many different geomorphic features within the oceans are called ridges.
Nov 28, 2022 · Ocean ridges form where new lithospheric crust is generated by seafloor spreading at tectonic plate boundaries. Some stretch for tens of thousands of kilometres through the oceans, but others can be quite short e.g., in back arc basins.
Ocean ridges host a range of habitats including hydrothermal vents, rocky slopes, and soft sediments, all with connections to the pelagic ecosystem above. Mid-ocean ridges stretch for tens of thousands of miles through the oceans, but other plate-boundary ridges can be quite short e.g., in back arc basins. ...
