Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of kilometres wide.
The mid-ocean ridge is a global system of underwater volcanoes that forms new ocean crust along divergent plate boundaries. Learn about its shape, speed, location and how NOAA Ocean Exploration studies its volcanic, tectonic, hydrothermal and biological systems.
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 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.
10 Νοε 2020 · Mid-ocean ridges are undersea volcanic mountains that form where tectonic plates are spreading apart. Learn about their features, volcanism, and scientific research at WHOI.
The oceanic ridge system is the largest feature of the Earth’s surface after the continents and the ocean basins themselves; it is explained by the theory of plate tectonics as a boundary between diverging plates where molten rock is brought up from deep beneath the Earth’s crust.
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 (Fig. 1) reveals that many different geomorphic features within the oceans are called ridges.
