Review of Short Phrases and Links

    This Review contains major "Oceanic Ridge"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. An oceanic ridge is an underwater mountain range, usually formed by plate tectonics. (Web site)
  2. The oceanic ridge is cut by faults normal to the ridge.
  3. This type of oceanic ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading. (Web site)

Rift

  1. Running along the middle of an oceanic ridge, there is often a deep crevice known as a rift, or median valley. (Web site)

Subduction Zone

  1. It occurs when an oceanic ridge (spreading plate boundary) crosses a subduction zone.

Plate Tectonics

  1. See also: Oceanic ridge, plate tectonics, earth science, list of landforms. (Web site)

Iceland

  1. One of the only places where an oceanic ridge reaches above sea level is at Iceland, along the Mid-Atlantic Ridge. (Web site)
  2. Iceland is sometimes cited as a third classical example, but complicated by the coincidence of a hotspot intersecting a oceanic ridge constructive margin.

Mid-Ocean Ridge

  1. Also known as mid-ocean ridge; mid-ocean rise; oceanic ridge. (Web site)

Rift Valleys

  1. Rift valleys are found on the continents and along the crests of oceanic ridge s. (Web site)

Subduction Zones

  1. Transform faults occur on land, connect segments of the oceanic ridge, and provide the mechanism by which crust can be carried to subduction zones.

Oceanic Trench

  1. Four principal depth zones can be identified in the oceans; continental shelf (and rise), abyssal plain, oceanic ridge, and oceanic trench.

Plates

  1. Each plate consists of rigid rock created by upwelling magma at oceanic ridge s, where plates diverge. (Web site)
  2. Volcanism can also occur along the axis of an oceanic ridge, where the plates move apart and magma wells up from the mantle. (Web site)

Ridge

  1. Here, basaltic magma is erupted at the oceanic ridge and is intruded beneath the ridge where it forms new oceanic crust.

Boundary

  1. Pacific-Antarctic Ridge is an oceanic ridge at the boundary between the Pacific and Antarctic Plates.

Seafloor

  1. The cause of the subsidence is attributed to the sinking of the seafloor as it moves down the flanks of an oceanic ridge.

Oceanic Ridge

  1. Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches.
  2. The Chile Rise is an oceanic ridge at the boundary between the Nazca and Antarctic Plates. (Web site)
