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-ocean ridge is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying in the deep ocean.
10 Νοε 2020 · The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater. It is a central feature of seafloor terrain that is more varied and more spectacular than almost anything found on dry land, and includes a collection of volcanic ridges, rifts, fault zones, and other geologic features.
Learn about the mid-ocean ridge, the longest chain of mountains on earth, where new ocean floor is created by plate tectonics. Discover how volcanoes, earthquakes, hydrothermal vents, and deep sea animals shape this diverse and dynamic environment.
As the oceanic plates move apart at mid-ocean ridges, rocks from Earth's mantle, far below, rise to fill the void, mostly via slow plastic flow.
16 Ιουν 2024 · The mid-ocean ridge is a global system of mountains and valleys formed by the movement of tectonic plates. It spans 40,389 miles around the globe and is the largest single volcanic feature on the Earth.
10 Απρ 2024 · Mid-ocean ridges (MORs) are quintessential sites of tectonic extension 1, 2, 3, 4, at which divergence between lithospheric plates shapes abyssal hills that cover about two-thirds of the...
