澳大利亚国立大学的科学家在地球外核中发现了一个甜甜圈形状的区域,地表下2 900公里。 Scientists at the Australian National University discovered a doughnut-shaped region in Earth's outer core, 2,900 km beneath the surface. 该区域与赤道平行,具有独特的特性,有助于保护生命免受太阳辐射的地球磁场。 This region, parallel to the equator, has unique properties contributing to the planet's magnetic field, which protects life from solar radiation. 这一发现是利用大地震地震的地震波进行的,揭示了甜甜圈形状区域存在较轻的化学元素,使地球磁场动态和核心组成变得明亮。 The discovery, made using seismic waves from large earthquakes, reveals the presence of lighter chemical elements in the doughnut-shaped area, shedding light on Earth's magnetic field dynamics and core composition.
