地球体温有点高一层薄薄的地壳包裹在外面,向内是温暖的、可流动的地幔,再向内先是液态的外地核,最内部是致密的铁镍金属内地核——这幅地球剖面图是中学地理课本上的经典图画,地球的“鸡蛋型”内部结构似乎是板上钉钉的科学事实。
The Earth’s body temperature is slightly higher than the thin crust of the Earth, surrounded by a warm, flowable mantle and then the liquid core, the innermost part of which is the dense iron-nickel metal core - the Earth’s cross-section The map is a classic drawing of geography textbooks in high school. The internal structure of Earth’s “egg type” seems to be a scientific fact.
