內地核

地球的內核，是地球的最深層的部?，半徑1220公里 ^[1]^[2]。一般相信?以鐵 - ? 之合金組成，以及大?與太陽表面溫度相同，約?5700 開氏度。

?度??力 [ ?? ]

?地核的?度??力可以通?理????方式??出?在?地核?外地核?界?力（?330 GPa）?的融化?度。?度???5,700 K（5,400 °C；9,800 °F）。 ^[3] ?地核的?强略高于?外地核?界：??在330至360吉?斯?（3,300,000至3,600,000標準大氣壓）。 ^[4]?在??高的?力下是固?，因?其熔点 ??力??性增高（?? 克?修斯－克拉佩?方程）。 ^[5]

Science ?志上的一篇?文 ^[6]???地核?界?的熔点是6230 ± 500 K。
