Mid ocean ridge diagram. From 2,000 to 3,000 meters, mid-ocean ridges appear that span the length of the Arctic, Pacific, and Indian oceans. From 3,000 to 6,000 meters of ocean drained, these aquatic mountains slowly give way to the vast majority of the ocean floor. Little changes over the final 5,000 meters except to illustrate just how deep the ocean's trenches reach. oceanic ridge, any of several continuous submarine mountain chains rising from the ocean floor. Individually, oceanic ridges are the largest features in ocean basins.Collectively, they form the oceanic ridge system, which extends approximately 80,000 km (50,000 miles) through all the world's oceans and thus constitutes the most prominent feature on Earth's surface after the continents and ... Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, ... 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 rise in the mantle beneath the ...
Jun 08, 2015 · For instance, a mid-ocean ridge system in Panthalassa—an ancient ocean that surrounded the supercontinent Pangaea—contributed to shallower oceans and higher sea levels in the Paleozoic era. Panthalassa was an early form of the Pacific Ocean, which today experiences less seafloor spreading and has a much less extensive mid-ocean ridge system. The plate tectonic cycle produces chemically distinct mid-ocean ridge basalts and arc volcanics, with the latter enriched in elements such as Ba, Rb, Th, Sr and Pb and depleted in Nb owing to the ... The ridge-push hypothesis suggests after the initial rifting event, plates continue to be pushed apart by mid-ocean spreading centers and their underlying convection currents. Slab-pull proposes the plates are pulled apart by descending slabs in the subduction zones of the oceanic-continental margins [ 80 ].

Mid-Ocean Ridges. Mid-ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge. New lithosphere is created by volcanic activity along the crest of the ridge, and the plates on either side of the ridge are moving away from one another.

Middle English rigge, from Old English hrycg "back of a man or beast," probably reinforced by Old Norse hryggr "back, ridge," from Proto-Germanic *hruggin (source also of Old Frisian hregg, Old Saxon hruggi, Dutch rug, Old High German hrukki, German Rücken "the back"). OED says "of uncertain relationship;" Pokorny, Boutkan, and Watkins have it from PIE *kreuk-, extended form of root *sker- (2) "to turn, bend." The original "back" sense, predominant in Middle English, seems to have become archaic 17c. Also in Old English, "the top or crest of anything," especially when long and narrow, based on resemblance to the projecting part of the back of a quadruped, the "ridge" of the backbone. Probably also in late Old English "a long elevation of land, a long, narrow range of hills," implied in place-names. From late 14c. of the highest part of the roof of a building, also the strip of ground thrown up between two plowed furrows. The spelling with -dg- is from late 15c.

c. 1300, occean, "the vast body of water on the surface of the globe," from Old French occean "ocean" (12c., Modern French océan), from Latin oceanus, from Greek ōkeanos, the great river or sea surrounding the disk of the Earth (as opposed to the Mediterranean), a word of unknown origin; Beekes suggests it is Pre-Greek. Personified as Oceanus, son of Uranus and Gaia and husband of Tethys. In early times, when the only known land masses were Eurasia and Africa, the ocean was an endless river that flowed around them. Until c. 1650, commonly ocean sea, translating Latin mare oceanum. Application to individual bodies of water began 14c. (occean Atlantyke, 1387); five of them are usually reckoned, but this is arbitrary. The English word also occasionally was applied to smaller subdivisions, such as German Ocean "North Sea."
"middle; being the middle part or midst; being between, intermediate," Old English mid, midd from Proto-Germanic *medja- (source also of Old Norse miðr, Old Saxon middi, Old Frisian midde, Middle Dutch mydde, Old High German mitti, German mitte, Gothic midjis "mid, middle"), from PIE root *medhyo- "middle." By late Middle English probably felt as a prefix only, and now surviving in English only as a prefix (mid-air, midstream, etc.). Prefixed to months, seasons, etc. from late Old English. As a preposition, "in the middle of, amid" (c. 1400) it is from in midde or a shortened form of amid (compare midshipman) and sometimes is written 'mid.
This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years.

Mid-ocean ridge | UPSC - IAS. One of the most striking features of the ocean floor is the distribution of mid oceanic ridges. These ridges are mountain-like structures standing well above the deep ocean floors. The mid oceanic ridges are, in total, 65,000 km long and cover almost 23% of the earth's surface.

The patterns reflect the creation and spreading of oceanic crust along the mid-oceanic ridges. Basalt forming at the ridge crest picks up the existing magnetic polarity. Divergence then moves the swath of fresh crust away from the ridge. As long as the magnetic field remains constant, the polarity “stripe” widens.
Mid-ocean ridges are how oceans are born, grow, and mature. Right now, Africa and Arabia are pulling apart, a process called continental rifting, and the Red Sea between them is widening at an ...

This is for "above average" general readers. If the book averages two or more footnotes per page, think twice and justify its inclusion. Secondary and tertiary sources are *strongly* favored: this is for general readers. Feel free to ignore these suggestions, but include reasons for why you are ignoring it (ie, "This is an academic work, but is highly readable").
