29 Οκτ 2018 · The ridges are the divergent zones where oceanic plates are born, spreading apart from the central valley, or axial trough. This map shows the overall configuration of the ridges and their names. Click the image for a 900-pixel version.
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 system 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 underwater, in the deep ocean.
Bathymetric map showing a global view of the mid-ocean ridge (MOR). The mid-ocean ridge wraps around the globe for more than 65,000 km like the seam of a baseball, with an average depth to the ridge crest of 2500 m. Click image for larger view and image credit.

16 Ιουν 2024 · The longest mountain range on Earth is called the mid-ocean ridge. Spanning 40,389 miles around the globe, it's truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean.
1 Μαρ 1998 · We have now mapped nearly one-half of the global mid-ocean ridge system along a narrow corridor that defines the spreading center plate boundary, a remarkable advance considering we had mapped less that one percent of the system only a decade ago.
