Seismic mantle tomography maps
Surface projected global horizontal seismic S-wave velocity anomaly maps for different mantle depths revealing the two large low shear-wave velocity provinces (LLSVPs).

A sketch outlining the link between the viscous convection within the Earth’s mantle and tectonic surface plate motions.
Simplified model of the Earth’s interior and its global dynamics featuring a solid inner and a fluid outer core, a viscous partially molten but not fluid mantle, and characteristic surface topography.
Comparison of suggested mantle convection in the Earth (mobile-lid mode) and Venus (inefficient short slab mode).
Sketch of an evolution of an opening and sinking slab gap during oceanic subduction and the resulting surrounding mantle flow.
