6-Considering the effects of the conditions explained previously in parts 3, 4, and 5, it is evident that during the rotation of molten and doughy materials inside the earth, if a distinct and huge mass of high density situates itself in the vicinity of a certain area of the earth’s surface ,the gravitational force in that area will increase ( although it is relatively very slight ).If this region includes the Caspian sea  domain ,the following phenomena will occur :

 6-1-Considering that the total volume of the Caspian sea water is estimated at 500 thousand billion cubic meters,even a slight increase in the " g " factor applied to the wide surface and the great volume of water of the Caspian sea, would cause the body of the sea water  to be attracted or drawn with a more gravitational force toward the center of the earth, since the surface of the sea water is a part of the earth sphere, this additional gravitational force causes the convexity on the curvature of sea water surface to diminish (e.g. drop of 25 centimeters from 3000 meters arch rise in the middle of the sea ), and the surface of the middle part of the sea goes down, since the volume of water should remain constant , the water level in the coastal zone goes up and it is clear that this rising would be maximum in the coastal line ( the width of coastal zone in every side of the sea is estimated to be about %5 of the width of sea at the selected section ).Likewise when a huge bulk of molten and doughy materials with lower density situates in the vicinity of a certain area of that part, ( it replaces the high density bulk ) ,the situation is opposite , so that in the middle part ,the surface goes up and in the coastal zone the surface goes down , (like the effect of the gravitational force of the moon on  the oceans and seas from a distance of 400,000 km.Since this distance is very long,it has a slight effect on  “ g “,however this slight change causes tide every 24 hours).

 Conclusion:

 First : The major rise of sea surface level in the coastal zone of the Caspian sea will always be accompanied by a major fall of sea surface level in the mid part of the sea   ( and vice versa ).

Second - If the position, and situation of huge and distinct bulks of molten and doughy materials with high density and those of low density are symmetric with respect to the earth’s center , regarding the interval between previous occurrences of the fluctuations of the Caspian sea level ,one can predict that the next major falling of sea level in coastal zone will approximately happen in 2050 , and the next major rising will be in 2100 ( the tracing its way is also possible ).

 7- The schematic diagram for the rising of the sea level in the coastal zone , and falling of the sea level in the middle part , is shown below ( that is what happened  during 1987- 94 ). Since the inverse process ,i.e. falling of the sea level in the coastal zone and rising of sea level in the middle part ( that happened during 1933 - 41 ) , is essentially the same in principle, its diagram and the curve of gm are not presented.
