Hot spots are used as a proof of P2T, the continent sliding over a stationary mantle hot spot. Everything is in motion, mantle, core, convection cells, crustal plates (oceanic and continental). And yet, the Hawaiian Islands exist. The theory is the ocean plate was sliding over a number of stationary mantle plumes as they erupt and create volcanic islands. But if hot spots are stationary in the core or lower mantle how does the rising heat pass through the convection cells in the upper mantle? Not once but twice? explain in theory Hot spots are used as a proof of P2T, the continent sliding over a stationary mantle hot spot.
