地球的核心可能含有足以形成45个海洋的氢,这表明自地球形成以来就存在水。
Earth’s core may contain enough hydrogen to form 45 oceans, suggesting water existed since Earth’s formation.
根据《自然通讯》发表的一项研究,地球核心的含氢量可能比地球海洋的含氢量多45倍。
Earth’s core may hold up to 45 times the volume of Earth’s oceans in hydrogen, according to a study published in Nature Communications.
研究人员利用高压实验和高级分析,发现氢占核心重量的0.07%至0.36%,这表明氢是45亿多年前地球形成时所含的。
Using high-pressure experiments and advanced analysis, researchers found hydrogen makes up 0.07% to 0.36% of the core’s weight, suggesting it was incorporated during Earth’s formation over 4.5 billion years ago.
这挑战了早先的理论,即地球的水后来通过彗星运来,相反地表明水和氢来自地球早期的开发。
This challenges earlier theories that Earth’s water arrived later via comets, indicating instead that water and hydrogen were present from the planet’s early development.
研究结果表明核心在地球氢循环中起着关键作用,并可能影响地球的磁场和内部动态。
The findings imply the core plays a key role in Earth’s hydrogen cycle and may have influenced the planet’s magnetic field and internal dynamics.
