   Mantle 1 地幔


  We are living on the surface of the Earth. 我们生活在地球表面。
  So, what is inside the Earth? 那么,地球内部是什么?
  There is a mantle under the surface of the Earth. 地球表面以下是地幔。
  The mantle takes up 84% of the Earth. 地幔占地球体积的84%
  It is a rocky layer, and it covers the core of the Earth. 它是岩层,包裹着地核。
  The mantle near the surface is like a bunch of hard rocks. 靠近地表的地幔就像一堆坚硬的岩石。
  But the mantle near the core is boiling liquid rocks. 而靠近地核的地幔是炽热的岩浆。
  When a volcano erupts, this boiling mantle comes out. 火山喷发时,炽热的地幔随之而出。
  Also, the mantle heats up undergroud water. 而且,地幔会加热地下水。
  Thanks to the mantle, we can enjoy a hot spa. 多亏有了它,我们才可以享受温泉。

n.斗篷,覆罩之物,罩子;v.罩住,覆盖,脸红
  • The earth had donned her mantle of brightest green.大地披上了苍翠欲滴的绿色斗篷。
  • The mountain was covered with a mantle of snow.山上覆盖着一层雪。
