Continuous, median, seismic mountain range on the ocean floor, running through the North and South Atlantic oceans, the Indian Ocean, and the South Pacific Ocean.
A continuous, volcanically active mountain range extending through the North and South Atlantic Oceans, the Arctic Ocean, the Indian Ocean, and the South Pacific Ocean. It is a broad, fractured swell with a central rift valley, and usually extremely rugged topography. It is 1-3 km in elevation, about 1500 km in width, and over 84,000 km in length. According to the theory of sea-floor spreading, new oceanic crust is created by volcanic eruptions at the mid-ocean ridge.
mountain range that runs along the ocean bottom formed at the boundaries of oceanic plates. The base is in very deep water and the top may break through the ocean surface to form oceanic islands, such as the Western Azores.
An underwater mountain ridge with volcanoes, formed where two tectonic plates move apart.
A major elevated linear feature of the seafloor consisting of many small, slightly offset segments, with a total length of 200 to 20,000 km. A mid-ocean ridge occurs at a divergent plate boundary, a site where two plates are being pulled apart and new oceanic lithosphere is being created.
A 2-km-high submarine mountain belt that forms along a divergent oceanic plate boundary.
a boundary between plates where new lithospheric material is injected from below
A nearly continuous undersea mountain chain that marks the location where tectonic plates (pieces of the lithosphere) are moving apart. Mid-ocean ridges are the locations of creation of new ocean crust.
A huge underwater mountain range.
A submarine mountain chain located along the divergent plate boundaries in the ocean. New oceanic crust forms as magma cools and solidifies at the ridge.
A 50,000 km submarine mountain range along which oceanic plates are formed.
ridge on the ocean floor where oceanic crust forms and from which it moves laterally in opposite directions.
A type of tectonic plate boundary where two tectonic plates are moving apart (also called a "spreading center"). Volcanic activity creates a ridge at the boundary.
A chain of undersea mountains in every ocean that circles the earth like the seam of a baseball for nearly 37,000 miles (59.545 km) and is the site of active seafloor spreading.
The site where tectonic plates move apart and new oceanic crust is created.
A continuous mountain range with a central valley, located on the ocean floor where two tectonic plates move away from each other allowing molten rock from the Earth's interior to move toward the surface.
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. The mid-ocean ridges of the world are connected and form a single global mid-oceanic ridge system that is part of every ocean, making the mid-oceanic ridge system the longest mountain range in the world, with a total length of about 60,000 km.
