Abstract
In present, contribution paleogeographical maps for the time interval 0.6 Ga BP to present are analyzed in terms of (a) the ratio between continental to oceanic crust areas in order to estimate the speed of continental growth and (b) the surface motion of continental plates under the influence of global forces of tidal friction and Eotvos force ("pole-fleeing"). It is concluded that the area of the continents during the Phanerozoic was growing and it exhibited a rate similar to 0.5 km(3)/year. It is also found that beside the westward-oriented tidal frictional forces the Eotvos force can play also a role in tectonical processes. It is shown that the continental plates on average tend to find a position close to the equator during the whole investigated 600 Ma time interval.
