WebMid-ocean ridges are created by the upwelling of basaltic lava and lateral rifting of ocean crust (Figure 6.12 ). They form a rift valley system that encircles the Earth along a total length of over 75,000 km ( Figure 6.11 ). The mid-ocean ridges are the earth’s largest volcanic system, accounting for >75% of all volcanic activity on the planet. http://ccom.unh.edu/seminars/bernard-coakley-2024 china buffet xenia ohio
