   Magmas 岩浆


  Have you heard about liquid rock? 你听说过液态岩石吗?
  It might sound funny to you. 这听起来可能很好笑。
  How can a rock be liquid? While it can be. 岩石怎么可能是液体呢?但有时它还真是。
  If the temperature is very high, rock melts. 如果温度非常高,岩石就会熔化。
  What do you call this melted rock? Magma. 我们怎么称呼这种熔化的岩石呢?岩浆。
  So where can we see magma? In volcanoes. 那么我们能在哪儿看到岩浆呢?在火山里。
  Inside volcanoes, the temperature is over 700℃. 在火山内部,温度超过700℃。
  So the temperature is high enough to melt rocks. 这么高的温度足以熔化岩石。
  When a volcano erupts, magma comes out. 当火山爆发时,岩浆喷涌而出。
  The color of magma is red. 此时,它的颜色是红的。
  But when magma is cooled and becomes solid rock, it becomes black. 但当岩浆冷却变成固体岩石时,它就变成了黑色。
