  2. Rift - Wikipedia

    en.wikipedia.org/wiki/Rift

    The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.

  3. Divergent boundary - Wikipedia

    en.wikipedia.org/wiki/Divergent_boundary

    Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.

  4. Mid-ocean ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-ocean_ridge

    Mid-ocean ridges exhibit active volcanism and seismicity. [3] The oceanic crust is in a constant state of 'renewal' at the mid-ocean ridges by the processes of seafloor spreading and plate tectonics. New magma steadily emerges onto the ocean floor and intrudes into the existing ocean crust at and near rifts along the ridge axes. The rocks ...

  5. Rift zone - Wikipedia

    en.wikipedia.org/wiki/Rift_zone

    A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a set of linear cracks (or rifts) develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent. [1]

  6. African plate - Wikipedia

    en.wikipedia.org/wiki/African_Plate

    This rift zone separates the African plate to the west from the Somali plate to the east. One hypothesis proposes a mantle plume rising beneath the Afar region pushing the crust outward, whereas an opposing hypothesis explains the rifting by dynamics in the crust, as a break in the African plate along a line of maximum weakness as plates to its ...

  8. Seafloor spreading - Wikipedia

    en.wikipedia.org/wiki/Seafloor_spreading

    Hess' theory was that new seafloor is formed when magma is forced upward toward the surface at a mid-ocean ridge. If spreading continues past the incipient stage described above, two of the rift arms will open while the third arm stops opening and becomes a 'failed rift' or aulacogen. As the two active rifts continue to open, eventually the ...

  9. Mid-Atlantic Ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-Atlantic_Ridge

    The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate , north and south of the Azores triple junction .
