The origin of water on Earth. The elements in the universe are caused by nuclear fusion processes at the Central pith of carbon, oxygen, hydrogen, helium stars include silicon and iron. Solar system originated from the dust and gas in the solar nebula (Solar nebula), when approximately 4600 million years ago. The world caused by the aggregation of all the Meteors (Planetisimal) early in the world of hot magma. Substances such as metal, steel has a high specific gravity. Sink down that transformed the world. Non-metallic substances such as silica (SiO2) has a low specific gravity, floating on the Earth's crust. Light element such as substances section, hydrogen, carbon dioxide and water vapor into the atmosphere raises. The surface of the Earth in the first age there are high temperatures filled with lava, and the volcano. Later, when the Earth cool down. The steam condenses into droplets so the waterfall into the surface world. The Crashworthiness of a Comet, which has a lot of elements is ice. Makes the surface water accumulation in the lower world, becoming a marine and oceans as shown in picture 1.
