【一句话翻译】The oldest rocks on Earth (原文已加)

【汉译英 Chinese to English】

许多地质学家认为，地球上最古老的岩石形成于 30 多亿年前从地球熔融的金属核心升起的热柱之上，就像熔岩灯中的蜡一样。

Many geologists think the oldest rocks on Earth formed more than 3 billion years ago above hot plumes that rose from Earth’s molten metallic core, rather like wax in a lava lamp.
