英文原文

In the realm of scientific inquiry, a lesser-known yet fascinating field is the study of geomagnetism – the study of Earth's magnetic field and its interactions with the environment. Geomagnetism plays a crucial role in numerous natural phenomena, from navigation using compasses to protecting our planet from harmful solar radiation.

在科学探索的广阔领域中，有一个鲜为人知却引人入胜的领域，那就是地磁学——研究地球磁场及其与环境的相互作用。地磁学在许多自然现象中扮演着至关重要的角色，从利用指南针进行导航到保护我们的星球免受有害太阳辐射的影响。

One of the most intriguing discoveries in geomagnetism is the existence of magnetic reversals. These occur periodically throughout Earth's history, where the polarity of the magnetic field flips – north becomes south, and vice versa. Scientists have documented numerous such reversals in the geological record, with the most recent one occurring approximately 780,000 years ago.

地磁学中最引人入胜的发现之一是磁极反转的存在。这些反转在地球历史上周期性发生，即磁场的极性翻转——北极变成南极，反之亦然。科学家在地质记录中记录了许多这样的反转，最近一次发生在大约78万年前。

Understanding the mechanisms behind magnetic reversals remains a challenge for geophysicists. Current theories suggest that they are linked to the movement of Earth's tectonic plates and the convection of molten rock in the planet's core. However, the exact triggers and consequences of these events are still largely unknown, making geomagnetism a frontier of scientific research.

了解磁极反转背后的机制仍然是地球物理学家面临的挑战。目前的理论认为，它们与地球板块的运动和地球核心熔融岩石的对流有关。然而，这些事件的确切触发因素和后果仍然在很大程度上未知，这使得地磁学成为科学研究的前沿领域。
