New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to ...

At divergent boundaries in the oceans, magma from deep in the Earth's mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along the seam.

The estimate is 50% of plate tectonic movement is driven by this heat, and about 20 terawatts of heat flows between the core and the mantle. That's just slightly more than the average total power ...

This is a preview. Log in through your library . Abstract Volcanism on Earth is known to occur in three tectonic settings: divergent plate boundaries (such as mid-ocean ridges), convergent plate ...

My graduate research has been focused on the solid Earth processes that are controlled by magmatism and tectonics. Specifically, from a geodynamic perspective, I formulate theoretical and numerical ...
