传统观点认为,夏威夷的火山岛由一个直通地球炙热核心的热岩地幔柱形成,这个热岩地幔柱现仍在给火山岛“供料”。一项新的研究对于这一传统观点提出挑战。根据传统观点认为随着地壳在地幔柱上方滑动,海床喷出熔岩,在数千万年的岁月变迁中,冷却的熔岩层形成山脉和岛屿。美国科学家表示,经过 Traditionally, Hawaii’s volcanic island has been formed by a hot-rock plume directing the hot core of the Earth, which is still “feeding” the volcanic island. A new study challenges this traditional view. According to the traditional view, as the crust slides above the mantle plume, lava is ejected from the sea floor, and cooled lava layers form mountains and islands for tens of millions of years. American scientists said that after
