Recently, a number of research findings have come to light about the age of plate
tectonics, and energies are needed to operate it. The aim of present study is to investigate
whether the energy of plate tectonics process was different during the Phanerozoic
(Pz) and in earlier eons, and if there is such a discrepancy, whether it can be justified
by changes in the processes that able to move the plates. The study will track temporal
changes in important components of plate tectonics such as length of mid‐ocean ridges,
subduction zones and relative oceanic crust coverage during Phanerozoic. Next, it
will be examined how the knowledge gained in this way can be reconciled with the results
of studies of previous eons. It was found that the temporal variation in kinetic energy
of axial rotation due to changes in length of day (LOD) can be assumed as a determining
energy which acts on the tectonic plates as in the Phanerozoic as earlier in Archean
(Arch) and Proterozoic (Ptz).
