  2. 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.

  3. List of tectonic plate interactions - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plate...

    Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...

  4. Plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Plate_tectonics

    Divergent boundary. Divergent boundaries (constructive boundaries or extensional boundaries). These are where two plates slide apart from each other. At zones of ocean-to-ocean rifting, divergent boundaries form by seafloor spreading, allowing for the formation of new ocean basin, e.g. the Mid-Atlantic Ridge and East Pacific Rise. As the ocean ...

  5. Mid-ocean ridge - Wikipedia

    en.wikipedia.org/wiki/Mid-ocean_ridge

    A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading ...

  6. Indo-Australian plate - Wikipedia

    en.wikipedia.org/wiki/Indo-Australian_Plate

    The northern margin of the Indian plate forms a convergent boundary with the Eurasian plate, which constitutes the active orogenic process of the Himalayas and the Hindukush mountains. The northeast side of the Australian plate forms a subduction boundary with the Eurasian plate in the Indian Ocean between the borders of Bangladesh and Burma ...

  7. Outline of plate tectonics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_plate_tectonics

    Where the plates meet, their relative motion determines the type of plate boundary (or fault): convergent, divergent, or transform. The relative movement of the plates typically ranges from zero to 10 cm annually. Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation.

  8. Eurasian plate - Wikipedia

    en.wikipedia.org/wiki/Eurasian_Plate

    The western edge is a triple junction plate boundary with the North American plate and Nubian plate at the seismically active Azores triple junction extending northward along the Mid-Atlantic Ridge towards Iceland. [2] [3] Ridges like the Mid-Atlantic ridge form at a divergent plate boundary. They are located deep underwater and very difficult ...

  9. Pacific plate - Wikipedia

    en.wikipedia.org/wiki/Pacific_Plate

    The plate formed because the triple junction had converted to an unstable form surrounded on all sides by transform faults, due to the development of a kink in one of the plate boundaries. The "Pacific Triangle", the oldest part of the Pacific plate, created during the initial stages of plate formation, is located just east of the Mariana ...
