That's thanks to something called plate tectonics.

这要归功于构造学说。

On the Moon, there are no continental plate tectonics.

在月球上没有大陆运动。

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

但它最终在一种被称为构造的过程中分裂出来。

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

火星现在没有构造运动，但有证据表明它曾经有过。

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

那么，为什么地球一样大小的金星上没有构造运动呢？

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

这些动了数吨的石头，几乎毁掉了一座雕塑。

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

这意味着，我构造学一样老。

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

地壳运动的不断加压从海平面上升起大量岩石、陆地。

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构造，再到岩石的微观图像的所有内容。

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

当然，地球的构造水并不是唯一使它与众不同的东西。

Earth has enough water to lubricate its plate tectonics.

地球有足够的水来润滑它的构造运动。

We know Earth is unique for having plate tectonics, liquid water on its surface and an oxygen-rich atmosphere.

我们知道地球是独一无二的，因为它拥有构造、表面液态水富含氧气的大气层。

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

这些桥梁是在构造之前建造的，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.

比这更古老的岩石已经被构造破坏或高度变形。

In fact, plate tectonics only became widely accepted in the late 1960s – more than half a century after Wallace's death.

事实上，构造学到了 1960 年代末期才被广泛接受，此时已经是华莱士去世后半个多世纪以后了。

It was brought to the surface by the forces of plate tectonics millions of years ago.

数百万年前，由于构造的力量，它被带到了地表。

C, climate change from plate tectonics.

C，构造引起的气候变化。

Plate tectonics influences the flow of ocean currents, which are important drivers of climate patterns worldwide.

构造影响洋流的流动，而洋流是全球气候模式的重要驱动力。

As we learn in the lesson on paleogeography and plate tectonics, the continents are always moving.

正如我们在古地理构造课上学到的，大陆总是在移动。

Although many scientists were skeptical, the idea was eventually accepted and played a critical role in establishing the theory of plate tectonics.

尽管许多科学家对此持怀疑态度，但这一观点最终被接受，并在构造理论的建立过程中发挥了关键作用。
