According to the CTH (G ~ t ^-2/3) , the gravitation pressure in the earth globe decreases continuously. Consequentlly, the earth slowly grows. On the basis of the Dirac hypothesis, Pascual Jordan had already developed, decades ago, the theory of the earth expansion [30] . It starts from the assumption that the  liquid primary earth  was definitely smaller due to the gravitation being larger at that time than today.  He assumed , when the surface of the earth solidified, the surface area corresponded to the total mainland area existing today, including the shelves and the shallow sea areas  (Fig. 13).
The theory of the earth expansion elegantly explains several geological phenomena:
-  The apparent bi-level altitudes of the earth surface (Fig. 14).
-  The global net of trenches, interpreted as the effect of tensile stress due to the earth expansion Fig. 15),
-   The exact matching of the African and South American coast lines,
-  The cause of volcanism, earth quakes and mountain build- up caused by the curvature decrease of the earth crust (Fig 13).
Logically, the earth expansion must have been considerably higher than that calculable from a solely elastic expansion due to a decreasing gravitation constant. Chemical conversions and phase changes of rock within the earth due to the decreasing gravitation pressure have effected an additional increase of volume.
