Abstract

Based on the surface structures, the planetary bodies of the Solar System can broadly be classified into three groups, each respectively resembling the surface of the Earth, Moon and Outer Planets. While the earth�s surface is marked by continents and oceans, its satellite Moon is pitted with perfectly circular marks with slight protrusion at the centre, which appear to be the impressions formed at the penultimate stage of solidification of a silicate melt. Because of low density, the prevalent concept conjectures the Outer Planets to be constituted of gaseous matter, while the present study interprets these giant objects are extensively expanded planets and are also composed of basaltic mantle and iron core. Based on the earth expansion theory, the author explains that originally the planet earth was considerably small and devoid of oceans when its mantle was adequately fluid owing association of ocean-forming water. The earth�s expansion was caused due to gravitational attraction of an extra-terrestrial planetary object that caused the original semi-fluid mantle to swell up forming a number of long and sinuous expansion cracks. In consequence of such expansion, the sialic crust was fragmented in to several distinct continental fragments, while through the expansion cracks or mid-oceanic ridges extensive molten magma of basaltic composition extruded and spread on both sides of the cracks forming rudimentary ocean basins. With further expansion of the earth the continental fragments were drifted apart from one another, thereby, enlarging the ocean basins, which were simultaneously filled up with water that surfaced as water-enriched volatiles along with magma emission. The outer planets which are also enormously expanded are distinguished by presence of ring structure occurring over the planetary surface towards the equatorial region.
