OCEANIC WATER WILL EARTH'S COAST  EVER BE FLOODED WITH OCEANIC WATER.?Bold text Assume if The Earth would be rounded enough without mountains & oceanic depression and that let the whole water mass to spread all over the sphere, then we would get  the water level upto a height of about 2000m over our head. Fortunately it is not merely a coincidence that Earth's surface is made up of 29.1% land mass restricting the water body in rest 70.9% with an average depth of 3800ms below the mean sea level. If the water mass  became multilpied  due to the melting of  ice from the frozen area then what percent of the land mass would get submerged ? Certainly it is not 10 % of the existing land as calculated but very lower percentage than that because of the fact that in that case the average depth of the ocean  would be increased up to the depth of 5000mts  to  accommodate  the extra water produced by  ice melting and the percentage of land mass will remain constant with respect to the ocean surface. This concept is proved by a new theory  THE HYDROPRESSURE THEORY OF CRUSTAL EVOLUTION & TECTONIC PLATE MOVEMENTS. . The Hydro pressure theory of crustal evolution & tectonic plate movement developed by this author postulates that it is the mass of water which is responsible for the crustal evolution as well as land formation. For example if one will take an water- wet ball & spin it with a high speed it is observed that the water particles will throw out of the surface of the ball. That is due to the effect of centrifugal force developed due to the spinning of th ball. If the ball spins speedily the centrifugal force will be more than a slow spinning ball. The force is directly proportional to the velocity & can be calculated from the formula F= MV2 / R   .where  F= force   M = Mass,  V= velocity & R= radius of the Circle This experiment is simulated in case of the Earth .The water mass ol the Earth try to escape to the space with the centrifugal force as calculated but fortunatelv restricted due to  the gravitational force of the earth. A reactional force equals to the  magnitude of the centrifugal force is generated according to the Newton's Third law  that tells that Every action have an equal & opposite rection. This force is the centripetal force which is developed as the reactional force. So the whole water mass put pressure on the earth's surface as ONE UNIT because of fluid  behaviour, to get the oceanic depression proportionate to the  centripetal force thus generated. This leads  the process of formation  oceanic crust which is as deep as average  3800mt below the  mean sea level. Due to the flexibility of the crust as it is supposed to float over a viscous  mantle, the rest part of the earth surface bulges out to an average height of 840 m above the MSL. The depth of  water in the ocean &  the height of the land mass will proportionately generated and depend upon the mass  the water .The calculation is as follows: .Centrifugal Force ot Earth  MV'2/R   =     React ional centripetal force approximately

I.44 X 1015 kg X 400 X 400 m2/ s2 = 2.3 X 1019  Newton force 6376000mt                                                                                 , Where M =mass of oceanic water  V=  spin of the  Earlh   R =   radius of the earth This reactional force is compensated by the creation of the depression in the shape of ocean &  bulging  of the land mass proportionately as nearly three part of mass of water with specific gravity 1( one) creates one part of the land mass with average specific gravity nearly 2.5. Again another force came in to existence i:e the pressure of water which exert pressure on the sides of the oceanic crust walls  &  responsible for the movement of continents. Oceanic water amounts 1.445 X   IO1' kg  mass  and  its pressure calculated   according   to   th PASCAL'S LAW    FORCE=PRESSURE X AREA     and      PRESSURE=  ρgh   where   ρ=  density g =acceleration due to gravity & h = height of waterD=thickness of the ocean floor. .Total pressure on 1 mt column   of the crustal block is calculated with the formula 1/2 ρgh X h X 1/3 (h + D) This huge force acted on the continental slope like the thrust of reservoir water on dam walls  & distributed in different parts  of the  ocean. The imbalance in the distribution of such force causes continental drift &  breaking of  continents like Africa. South America, Austalia & India from the Gondwanaland. This force also enables the oceanic floor to touch the Mantle to facilitate pouring out lava with  the formation  of Mid Oceanic ridges at  the very low pressure zone under the sea .This Hydropressure theory also suppliments the theories of Mountains building,theory of  Isostasy, Ocean floor spreading,continental drift& Island arc  which warrants more research.
