Until recently, the standard teaching has been that the Earth is comprised of? four layers: 教書 the crust, mantle4, o'uter Core5, and inner core. The fifth layer is within the inner core, and is being referred to by geologists' as an inner-inner core. In order to study the inner core, scientists have used earthquake waves to create images of this region. Over the past few decades, this imaging has shown some anomalies that scientists cannot account forº. Some of the data seems to suggest that the core is not entirely solid iron as once thought. Now mineral physicists and geodynamicists 10 are working to create models that may help clarify the makeup12 of this newly discovered layer of the Earth. ||| 字詞大補帖 科學家在今年三月公布,他們發現地球有新的明 顯地層。直到最近,標準的教科書都會寫說地球的結 構有四層:即地殼、地函、外地核與內地核。這個第 五層位在內地核裡,地質學家稱之為內內地核。為了 1. distinct [distinkt] a. 明顯不同的 2. be comprised of... 由……組成 comprise [kam praz ] w. 包括,由…… 構成 死亡,於完动自重、由编制: 口国
