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 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.
Oceanic ridge, any of several submarine mountain chains rising from the ocean floor. Individually, the ridges are the largest features in ocean basins. Collectively, they form the worldwide oceanic ridge system—at about 80,000 km (50,000 miles) long, Earth’s largest surface feature after continents and ocean basins.
The lines represent tectonic plate boundaries. Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. [1][2] The crust overlies the rigid uppermost ...
Definition. An oceanic ridge is a continuous mountain range that forms along the seafloor at divergent plate boundaries, where tectonic plates are moving apart and new oceanic crust is created.
Oceanic ridges are the topographic expression of linear or curvilinear zones along which the Earth's oceanic crust is created or modified. A glance at any detailed bathymetric chart reveals that many different geomorphic features within the oceans are called ridges.
The oceanic ridge is an extensive underwater mountain range formed by the action of tectonic plates that are constantly altered and moved, and by the heat emitted from the Earth's core.
