Possible evolution of magmatotectonic styles for a large silicate body like Earth. Examples from active Solar System bodies Io, Venus, and Mars are shown. Possible evolution of Earth is also shown. Strength of mantle convection is indicated by arrowed curve thickness. Plate tectonics requires certain conditions of lithospheric density and strength in order to occur and is likely to be presaged and followed by different styles of stagnant lid tectonics.
