然后，固态地球的内部变得炽热、熔融，引起某些物质上升到地球表面，其结果也许就形成了地层。

Then the inside of the solid earth became hot and molten causing certain materials to rise to the surface. This probably resulted in the formation of the earth's layers.

为了能够维持生命，这个新的星球不仅要有液态水，而且它的土表还必须是固态的，就像地球这样。

To be able to support life, the new planet would need not only to have water, but it would also need to be solid.
