By the conventional theories on planetary formation, major discontinuities in the interior of a planet should mainly be the result of compositional differentiation or phase change of material correlated with pressure/temperature gradients. Once the planet is formed and events impacting the planet are of significantly lower energy than its own mass, no significant changes in mantle layers are expected. Exchange and recycling of material between the interior and surface of a terrestrial planet like Earth is assumed to occur through mantle plumes and processes associated with plate tectonics. Although life on surface can certainly be affected by these processes, any correlation between mass extinctions of life on surface and mantle discontinuities is conventionally unexpected and would be hard to explain. Here it is argued that correlation between temporal distribution of major surface events and spatial distribution of internal discontinuities may not be surprising, and evidence is provided that such correlation indeed does exist.
