Nearly every day somewhere on the crest of the mid-ocean ridge there is likely to be an eruption of lava or an intrusion of magma that builds the ocean crust.

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. Webseafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them.
