地球形成时基本上是各种石质物的混合物，如果积聚过程持续~年，则短寿命放射性元素的衰变和固体颗粒动能的影响都不大。初始地球的平均温度估计不超过1000℃，所以全部处于固态。形成后，由于长寿命放射性物质的衰变和引力位能的释放，内部慢慢增温，以致原始地球所含的铁元素转化成液态，某些铁的氧化物也将还原。
When the earth was formed basically is a mixture of various stone, if the accumulation process continues in ~, short life of radioactive elements decay and solid particle kinetic energy are not. The average temperature of the earth's initial estimate does not exceed 1000 degrees, so all in solid state. After the formation, due to the release of long-lived radioactive substances decay and gravitational potential energy, internal slowly warming, that the primitive earth contains iron is converted to liquid form, some iron oxides will also be reduced.
液态铁由于密度大而流向地心，形成地核（这个过程何时开始，现 在已否结束，意见颇有分歧）。由于重的物质向地心集中，释放的位能可使地球的温度升高约2000℃。这就促进了化学分异过程，由地幔中分出地壳。地壳岩石受到大气和水的风化和侵蚀，产生了沉积和沉积岩，后者受到地下排出的气体和溶液，以及温、压的作用发生了变质而形成了变质岩。
The liquid iron because of its high density and flow into the heart, to form the core (this process began when, now has not ended, have different opinions). Due to the heavy material to the concentration of released potential can make the earth's temperature is about 2000 DEG C. This promotes the chemical differentiation process, separated by mantle crust. Crustal rocks by weathering and erosion of air and water, the sedimentary and sedimentary rocks, the latter by the gas and solution discharged from the underground, the effect of temperature, pressure and metamorphism and the formation of metamorphic rocks.
这些岩石继续受到以上各种作用，可能经受过多次轮回的熔化和固结，先形成一个大陆的核心，以后增长成为大陆。原始地球不可能保持大气和海洋，它们都是次生的。海洋是地球内部增温和分异的结果，但大气形成的过程要更复杂。
These rocks continue to be above all, may be subjected to melting and consolidation of cycle times, to form the core of a continent, later to become the mainland growth. The original earth may not keep the atmosphere and oceans, they are secondary. The oceans are the result of a moderate increase in the earth's interior, but the process of the formation of the atmosphere is more complex.
原生的大气可能是还原性的。当绿色植物出现后，它们利用太阳辐射使水气（H2O）和CO2发生光合作用，产生了有机物和自由氧。当氧的产生多于消耗时，自由氧才慢慢积累起来，在漫长的地质年代中，便形成了主要由氮和氧所组成的大气。
The primordial atmosphere may be reductive. When green plants appear, they use the sun's radiation to make water vapor (H2O) and CO2 photosynthesis, resulting in the production of organic and free oxygen. When oxygen is produced more than consumption, the free oxygen is slowly accumulated, in the long geological time, it formed the main nitrogen and oxygen in the atmosphere.
