The 50 pages that link to Mid-ocean ridge, each with the reason it gives.

• BasaltRelated: Basalt erupts along these ridges to create much of the ocean floor.

• Seafloor spreadingBroader topic: The site where spreading actually happens; every ridge is a spreading center.

• Oceanic crustRelated: Rising magma at ridges supplies most newly formed oceanic crust.

• Volcanic arcCompared with: Ridge volcanism occurs at divergent boundaries rather than above sinking plates.

• Mantle convectionRelated: The upwelling limb's surface trace, with ridge topography set by mantle temperature.

• Continental crustRelated: New crust is continuously produced here, unlike the long-lived continental record.

• Igneous rockRelated: Basaltic rocks at ridges record the creation of oceanic crust.

• Shield volcanoCompared with: Like shields, ridges commonly erupt basalt, but their setting and structure differ.

• SerpentinizationRelated: Faulting at ridges lets seawater reach hot ultramafic rocks.

• Transform faultRelated: Transforms offset ridge segments into a staircase of spreading and sliding.

• Hydrothermal circulationRelated: Newly formed hot crust drives vigorous circulation beneath ridge crests.

• Earth's mantleRelated: Mantle upwelling and melting supply magma that builds new ridge crust.

• Abyssal plainCompared with: Ridges rise far above abyssal plains and divide ocean basins.

• Flood basaltCompared with: Both involve basaltic magma, but ridge volcanism is sustained along plate boundaries rather than concentrated in brief continental outpourings.

• PeridotiteRelated: Partial melting of rising peridotite beneath ridges supplies much of the basaltic crust.

• SeamountRelated: Ridge volcanism can create volcanic peaks that stand apart from the ridge crest.

• Island arcCompared with: Ridge volcanism occurs at separating plates, not above a descending slab.

• Decompression meltingBroader topic: Mantle rises beneath ridges, melts as pressure drops, and feeds new seafloor.

• East Pacific RiseNarrower topic: The East Pacific Rise is one member of this global ridge system.

• Hotspot (geology)Compared with: Ridge volcanism is driven by plate separation, unlike volcanism centered away from boundaries.

• IslandRelated: Ridge volcanism can build islands where the ridge reaches the surface.

• Divergent boundaryBroader topic: This is the characteristic oceanic expression of plate divergence.

• GabbroRelated: Ridge magmatism produces gabbro beneath newly formed basaltic crust.

• Oceanic islandRelated: Ridge volcanism can build islands where elevated volcanic terrain reaches the surface.

• Gravity anomalyRelated: Ridge-associated gravity patterns reflect crustal thickness, heat, and seafloor relief.

• Harry HessBroader topic: Hess placed rising mantle material and new crust at these submarine chains.

• Antarctic PlateRelated: Several ridges form the Antarctic Plate’s spreading boundaries.

• Farallon PlateRelated: Seafloor spreading at ridges generated crust that became part of the Farallon Plate.

• Oceanic trenchCompared with: Ridges mark seafloor spreading, unlike trenches, where oceanic crust descends.

• Flux meltingCompared with: Ridge magmatism is chiefly driven by decompression, not fluids from a sinking slab.

• Vine–Matthews–Morley hypothesisRelated: The magma factory at the ridge axis is where each magnetic stripe is minted.

• Wadati–Benioff zoneCompared with: Shallow spreading seismicity contrasts with earthquakes reaching 700 km depth.

• Earth's crustBroader topic: Rising magma solidifies here to make new oceanic crust.

• Continental riftCompared with: It is the mature oceanic spreading system that a successful continental rift can precede.

• Juan de Fuca RidgeNarrower topic: The Juan de Fuca Ridge is a short, well-studied example of this global system.

• Oceanic plateauCompared with: Some plateau models invoke enhanced magmatism at spreading ridges rather than an isolated plume.

• Southeast Indian RidgeNarrower topic: The Southeast Indian Ridge is one example of this global seafloor-spreading system.

• Submarine volcanoRelated: Ridge crests host widespread volcanic eruptions beneath the sea.

• West Antarctic Rift SystemCompared with: The West Antarctic system is a continental rift, not a mature oceanic spreading ridge.

• Continental riseCompared with: It is a tectonic high in the ocean basin, unlike the depositional continental rise.

• Oceanic core complexNarrower topic: Oceanic core complexes develop within this spreading environment.

• SerpentiniteRelated: Ridge systems expose and fracture ultramafic rocks that seawater can serpentinize.

• Upper mantleRelated: Rising upper-mantle material partially melts beneath these spreading centers.

• Pacific–Antarctic RidgeNarrower topic: The Pacific–Antarctic Ridge is one segment of this global submarine system.

• PanthalassaRelated: Ridge systems generated crust that spread across Panthalassa's enormous seafloor.

• Seafloor spreading hypothesisBroader topic: The factory floor of the hypothesis: magma rises here to create fresh oceanic lithosphere.

• Southwest Indian RidgeNarrower topic: The Southwest Indian Ridge is one segment of this global system.

• Central Indian RidgeNarrower topic: The Central Indian Ridge is one segment of this global system.

• Oceanic basinRelated: Ridges divide ocean floors into basins and stand high above their abyssal plains.

• SeabedBroader topic: This volcanic ridge system creates new seabed.
