That's thanks to something called plate tectonics.

这要归功于板块构造学说。

On the Moon, there are no continental plate tectonics.

在月球上没有大陆板块运动。

It covered everything from the geochemistry to plate tectonics, to microscopic images of its rocks.

它涵盖了从地球化学到板块构造，再到岩石微观图像所有内容。

Plate tectonics created heat and pressure, that produced rock lighter than the ocean floor.

地壳板块运动不断加热和挤压从海平面上起大量岩石、陆地。

The tectonics trembled tons of stone and nearly decapitated a sculpture.

这些板块撼动了石头，几乎毁掉了一座雕塑。

Mars doesn't have plate tectonics today, but there's evidence it once did.

火星现在没有板块构造运动，但有证据表明它曾经有过。

Which means, I'm as old as plate tectonics.

这意味着，我和板块构造学一样老。

But it eventually split off in a process called plate tectonics.

但它最终在一种被称为板块构造过程中分裂出来。

So why is there no plate tectonics on Venus, which is the same size as Earth?

那么，为什么和地球一样大小金星上没有板块构造运动呢？

Of course, the Earth's plate tectonics and water are not the only things to set it apart.

当然，地球板块构造和水并不是唯一使它与众不同东西。

You know, volcanoes erupt in Hawaii, too, but that doesn't necessarily prove plate tectonics.

你知道，夏威夷也有火山喷发，但这并不一定证明板块构造论。

The bridges were built before plate tectonics, so we've got no retrofitting at all.

这些桥梁是在板块构造之前建造，所以我们根本没有改造。

The rocks older than this have been either destroyed or highly deformed through plate tectonics.

比这更古老岩石要么被板块构造破坏了，要么发生了严重变形。
