中文翻译:
我很高兴你们提出了关于地球内部组成的调查的问题。事实上,这是你们下次阅读作业的话题.
让我用课上最后一点时间来说说这个关于地球内部组成的问题。这里有在本世纪初的一些重要发现,它们帮助地质学家们更加精确地看到地球内部。
第一个关键性的发现是????。地震是因为地球内部震动导致的。
科学家们发现它们在地球内部穿越数千米。这一发现使得地质学家们去研究地球内部。
你看到的这研究把地球的震动分为两种类型:P波和S波。研究者们发现p波可以穿过固体和液体,而s波只能穿透固体。
1906年,英国地质学家发现p波在一定深度的地方运动变得慢起来,但是还是保持向更深的地方运动。另一方面,s波的反射消失了。因此,他的出结论,那条界限就在固体和液态核之间。
3年之后,另一条界线被发现了。它在【什么和什么之间】
关于地球还有很多东西要去研究,地质学家知道地核是热的,这从火山流动的【什么 我猜是岩浆】就能判断出来。我们至今不确定【什么....】
 
 
I'm glad you brought up question of our investigations into the make up the earth interior. In fact, since this is the topic of your reading assignment for next time.
let me spend some this last few minutes of class talking about it. there were several important discoveries in early part of this century that help geologists developed more accurat picture the earth interior.
the first key discovery had to do with science make wipes. remember their the vibrations cause by earthquacks.
well sicentist found that they trouble thousands miles through the earth interior. this finding enable geologists to study the inner parts of the earth.
you see the studies review that this vibrations were two typs: conpr or P waves and s or S waves. and researchers found that P wave travel throught both liqued and solids, while S waves travel only through solid matter.
In 1906,a British geologist discovered the P waves slow down and certain deep but keep traveling deeper .on the other hand,S waves either disappeared all over reflect the back so he concluded that the depth marked the boundry between the solid mental and liquid with core .
3 years later, another bundry was discovered that between the mental and the earth crast .
there still a lot to be learned about the earth. frinstens geologists know that the cores are hot. evidence of these the【】 floods of the vocanoes.but we still not sure what the source of the【】
