The plume's more southern location, Toomey said, adds fuel to his group's findings, at three different sites along the globe encircling mid-ocean ridge (where 85 percent of Earth's volcanic activity occurs), that Earth's internal convection doesn't always adhere to modeling efforts and raises new questions about how ocean plates at Earth's surface — the lithosphere — interact with the hotter, more fluid asthenosphere that sits atop the mantle.

Earth's oceans would disappear due to this process, if it weren't for water returning to the surface via volcanism (mainly at mid-ocean ridges).

The green layer is the lithospheric plate, which forms at the mid ocean ridge, then cools down and thickness as it moves away from the ridge.

For a long time people thought that ocean pH was regulated ultimately by reactions between deep seawater and sediments, but as Walt Allensworth February 5, 2015 at 3:08 pm, says there are so many black, and clear, vents along the midocean ridges spewing acidic water, that these probably maintain ocean pH instead.
