Through collisions, these plates can raise great mountains or send ocean floor to the depths of Earth's molten interior.

通过碰撞，这些板块可以升起巨大的山脉，或者将海底送到地球熔融的内部深处。

Eurasian plate into the Earth's interior.

入欧亚板块下方，进入地球内部。

Eurasian plate into the Earth’s interior.

入欧亚板块下方，进入地球内部。

These are bodies of igneous rock, often ore-bearing, that have risen as liquid magma from Earth's interior but solidified before they reached the surface.

这些是火成岩体，通常含矿，从地球内部以液态岩浆的形式上升，但在到达地表之前就凝固了。

Moreover, volcanoes play a role in Earth's carbon cycle, releasing carbon dioxide from Earth's interior and contributing to the planet's long--term climate.

此外，火山在地球的碳循环中发挥着重要作用，从地球内部释放二氧化碳，对地球的长期气候做出贡献。

If you add more weight above the surface, they sink lower into the earth's hot interior, and when they sink far enough, they soften and basically melt.

如果加重地面，它们会沉没到地球炙热的内部，当沉到足够深时，它们会变软并且熔化。

And we can basically fingerprint these different volcanic systems to understand where the fluids and the gases in the material are coming from within Earth's deep interior.

我们可以精确识别不同的这些火山系统，以了解材料中的液体和气体来自地球内部深处的哪里。

As new crust is added to the Earth's surface here, the other edge of the plate, perhaps thousands of miles away sinks back into the Earth's interior.

当新的地壳被添加到地球表面这里，另一个边缘的板块，也许处于几千英里外，下沉回地球的内部。

There were several important discoveries in the early part of this century that helped geologists develop a more accurate picture of the Earth's interior.

本世纪早期有一些重要的发现，能够帮助地质学家开发出一个更精确的地球内部的图片。

Well, scientists found that they traveled thousands of miles through the Earth's interior. This finding enabled geologists to study the inner parts of the Earth.

好吧，科学家们发现他们穿越了地球内部数千英里。这一发现使地质学家能够研究地球的内部。

Thomas Gold of Cornell has estimated that if you took all the bacteria out of the Earth's interior and dumped it on the surface, it would cover the planet to a depth of five feet.

美国康奈尔大学的托马斯·戈尔德估计，要是你把地球内部的细菌统统取出来堆在地球表面，那么就可把把这颗行星埋在15米深处——相当于四层楼的高度。

Proponents of the crack hypothesis consider this a widespread phenomenon and believe that magma's not coming up from deep within the Earth's interior, but rather from just beneath the surface crust.

裂缝假说的支持者认为这是一种普遍存在的现象， 并认为岩浆不是来自地球内部深处，而是来自地壳表面下方。

I try to understand what's happening from like a geological carbon cycle, how much carbon is coming out of volcanoes, how much is going back into the Earth's interior due to subduction processes and plate tectonic processes.

我试图从地质碳循环角度了解目前发生的情况，比如有多少碳从火山喷出，有多少碳由于俯冲过程和板块构造过程而回到地球的内部。

The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth's interior.

承载这些大陆的板块的相对运动已经被详细构建，但是一个板块相对于另一个板块的运动不能轻易地转化为相对于地球内部的运动。
