3 spheroid, rotating on its axis and revolving about the parent nebula. The orbit of this planet lay in the plane the ring formerly had occupied and whose bounds was the space occupied by the nebula before separation. A series of rings sluffed off of the equatorial bulge, each in turn forming the eight planets. The central mass was the sun. At the time of the origin of the different planets they were thought to be hot, gaseous and rotating and as they cooled and contracted their rate of rotation was accelerated which caused equatorial bulging in the planets until some of them in turn sluffed off separate rings which form satellites. According to the nebular hypothesis the earth was part of the big mass of gas or nebula which was hot at first and cooled down to a liquid and finally crusted over with a hard shell of rock while the interior was left as hot molten rock. This mass of gas which formed the earth was the fifth planet to be snuffed off. The atmosphere was hot and heavy with no water on the surface of the lithosphere because the surface was too hot for water to remain there without evaporation. In time the atmosphere cooled enough to allow condensation of water vapor and cause percipitation. At first water boiled off very quickly, in fact as quickly as it fell, but going through the same process time after time the temperature was gradually cooled sufficiently to allow water to remain on the surface. The surface water began the ocean basins. Gradually the air was cleared of its obnoxious gases and the earth was fit for living and growing things. To analyze this nebular hypothesis one finds certain points in favor of, but more points which do not favor the hypothesis. They are based on known laws and scientific knowledge.
