The change of the earth’s dimensions determined from paleogeographical data


It is shown that paleogeographical data give evidence for the increase of the Earth’s radius. The average annual increase computed is 0.5 mm/year. The formation of the continents and ocean basins may be easily explained on the basis of the Earth’s expansion. The rate of the annual radius increase derived from this explanation is in good agreement with the value determined from paleogeographical data. The theoretically computed duration of a transgression-regression period corresponds also with geological observations.
