On the basis of the latest achievements in nuclear physics, astronomy and geology, this study discusses the huge amount of heat energy released by large scale uranium and plutonium nuclear chain fissions occurring about 4.5 billion years ago on all the original terrestrial planets and their satellites including Earth and Moon, and its effect on them. Gravity differentiation of the new planet compositions resulted in spherical layer structure, i.e. a structure of the crust, mantle and core. The inner core, the center of Earth is solid under a very high pressure. Uranium and plutonium which deposited on the surface of the inner core continued their chain nuclear fission, but could not change the solid state of the inner core. The nuclear energy produced since then conducted outward in the form of heat convection. Uranium chain fission stopped around 4.5 billion years ago, while plutonium fission continued. Therefore, less heat was produced since then and Earth started to cool down. When the temperature of the melting magma decreased to 700~800℃, the magma started to condensate to form layers with light weighted granite magma condensing to thin layer firstly. Due to shocking of large tide and wind, the thin layer was fragmented into several blocks. Huge drifting objects formed due to convergence with basaltic magma below are so called continents and small blocks formed islands. With temperature gradually decreasing, the mantle started to cool down to solid. With temperature decreasing to or under 100℃, steam in atmosphere cooled into water and converged at depression areas on the surface, thus forming oceans and lakes. Therefore, basalt is widespread on the floor of oceans. Then the nuclear heat produced continually from top of the inner core released as "plume" and penetrated through the solid layer to the crust. Blocked by the Crust, the plumes concentrated and formed asthenosphere under the Crust. After heated, the crust rocks were softened and tended to flow toward low pressure areas. Kinetic energy of asthenosphere was strengthened by gravity of Sun and Moon as well as spinning of Earth. Such huge driving force triggered a series of activities, such as uplift, folding, faulting, metamorphism, magma, volcanoes and earthquakes. The Earth, as one of planets in the universal, is incessantly influenced by numerous events on Earth, but the leading factor controlling its evolution is nuclear energy. This study finally discusses the relationship betwween nuclear energh and emements and evolutiont of solar system.
