ridge
ridge
1. (wedge) An extension of high pressure from an anticyclone into a zone where generally lower pressure prevails.
2. The poleward meanders of the flow of the upper westerly winds over mid-latitudes.
3. (mid-oceanic ridge, oceanic ridge) A long, linear, elevated, volcanic structure that often lies along the middle of the ocean floor. Such ridges tend to occupy central positions because the oceans have formed by the symmetrical spreading of two lithospheric plates from the ridge sites. Oceanic ridges occur in all the Earth's oceans, but may be offset from a central position (e.g. the east Pacific ridge, where one side of the oceanic crust is being consumed along a subduction zone.
