The rock material flows up from Earth's interior here, at the split, which forces the two sides of the ocean floor to spread apart, to make room for the new rock material.
岩石物质从地球内部的裂缝处向上流动，迫使海底向两边分开，为新的岩石物质腾出空间。
Stone meteorites, which we refer to simply as stones, are almost entirely rock material.
我们简单地称之为“石头”的石头陨石，我们简单地称之为石头，几乎完全是由岩石组成的。
The latter two sources are limited to those few areas where surface water seeps down through underground faults or fractures to reach deep rocks heated by the recent activity of molten rock material.
后两种来源局限于少数区域，在这些区域，地表水通过地下断层或断裂往下渗透，从而接触到被近期的熔岩活动加热的深层岩石。
