Free Printable Mid Ocean Ridge Diagram Quick Reference A long linear elevated volcanic structure often lying along the middle of the ocean floor Such ridges tend to occupy central positions because the oceans have formed by the symmetrical spreading of two lithospheric plates from the ridge sites
The mid ocean ridge system is the most extensive chain of mountains on earth but more than 90 of this mountain range lies in the deep ocean The mid ocean ridge wraps around the globe for more than 65 000 km like the seam of a baseball The average depth to the crest top of the ridge is 2500 m but it rises above sea level in Iceland and is Template Mid ocean ridges 7 languages Related changes Upload file Special pages Permanent link Page information Wikidata item Print export Download as PDF Printable version This page was last edited on 6 October 2020 at 05 31 UTC Text is available under the Creative Commons Attribution ShareAlike License

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
Download image jpg 140 KB The massive mid ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball stretching nearly 65 000 kilometers 40 390 miles The majority of the system is underwater with an average water depth to the top of the ridge of 2 500 meters 8 200 feet

Rising up from the abyssal plain you would encounter the mid ocean ridge an underwater mountain range over 40 000 miles long rising to an average depth of 8 000 feet Tracing their way around the global ocean this system of underwater volcanoes forms the longest mountain range on Earth
Occur along mid ocean ridges Where the plates are moving apart magma may push up from the mantle forming new oceanic crust basalt The ocean ridge systems winds around our planet like the seam on a baseball Spreading rates range from 2 to 10 cm year The Atlantic ridge is spreading 2 5 cm year How far would the Diagram of oceanic ridge World Distribution of Mid Oceanic Ridges the big picture Age of oceanic crust youngest red is along spreading centres Seafloor spreading happens at the bottom of an ocean as tectonic plates move apart The seafloor moves and carries continents with it At ridges in the middle of oceans new oceanic crust is created
