Earth’s mantle heterogeneity theories
Conceptual model sketches for proposed compositional structures of Earth's mantle, including "Marble cake", "Thermo-chemical piles", and "Mid-mantle blobs" theories.

Sketches outlining the solid-Earth induced change of sea level over different time periods, covering elastic, viscous, and mantle convection time scales.
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).
The three deformation mechanisms viscous, elastic, and brittle (a.k.a. plastic).
