  2. Mid-ocean ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-ocean_ridge

    The mid-ocean ridges of the world are connected and form the Ocean Ridge, a single global mid-oceanic ridge system that is part of every ocean, making it the longest mountain range in the world. The continuous mountain range is 65,000 km (40,400 mi) long (several times longer than the Andes , the longest continental mountain range), and the ...

  3. Ridge push - Wikipedia

    en.wikipedia.org/wiki/Ridge_push

    Diagram of a mid-ocean ridge showing ridge push near the mid-ocean ridge and the lack of ridge push after 90 Ma. Ridge push is the result of gravitational forces acting on the young, raised oceanic lithosphere around mid-ocean ridges, causing it to slide down the similarly raised but weaker asthenosphere and push on lithospheric material farther from the ridges.

  4. Marine geology - Wikipedia

    en.wikipedia.org/wiki/Marine_geology

    Plate tectonics is a scientific theory developed in the 1960s that explains major land form events, such as mountain building, volcanoes, earthquakes, and mid-ocean ridge systems. [26] The idea is that Earth's most outer layer, known as the lithosphere, that is made up of the crust and mantle is divided into extensive plates of rock.

  5. Undersea mountain range - Wikipedia

    en.wikipedia.org/wiki/Undersea_mountain_range

    Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.

  6. Fracture zone - Wikipedia

    en.wikipedia.org/wiki/Fracture_zone

    Oceanic crust age differences and ridge-ridge transform faulting associated with offset mid-ocean ridge segments lead to the formation of fracture zones. A fracture zone is a linear feature on the ocean floor—often hundreds, even thousands of kilometers long—resulting from the action of offset mid-ocean ridge axis segments.

  7. Charlie–Gibbs fracture zone - Wikipedia

    en.wikipedia.org/wiki/Charlie–Gibbs_fracture_zone

    The Charlie–Gibbs fracture zone has large amounts of mid-ocean ridge igneous and metamorphic rocks. [3]: 2 At the eastern termination off shore of Newfoundland there is an igneous province found within the otherwise nonvolcanic rifted margin in the region of transition between oceanic and continental crust. [4]: 1135, 1143

  8. Southeast Indian Ridge - Wikipedia

    en.wikipedia.org/wiki/Southeast_Indian_Ridge

    The Southeast Indian Ridge (denoted by the yellow line) The Southeast Indian Ridge (SEIR) is a mid-ocean ridge in the southern Indian Ocean.A divergent tectonic plate boundary stretching almost 6,000 km (3,700 mi) between the Rodrigues triple junction) in the Indian Ocean and the Macquarie triple junction) in the Pacific Ocean, the SEIR forms the plate boundary between the Australian and ...
