That's thanks to something called plate tectonics.

这要归功于造学说。

On the Moon, there are no continental plate tectonics.

在月球上没有大陆运动。

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造，再到岩石微观图所有内容。

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

地壳运动不断加热和挤压从海平面上升起大量岩石、陆地。

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

这些撼动了数吨石头，几乎毁掉了一座雕塑。

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

火现在没有造运动，但有证据表明它曾经有过。

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

但它最终在一种被称为造过程中分裂出来。

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上没有造运动呢？

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

这意味着，我和造学一样老。

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

当然，地球造和水并不是唯一使它与众不同东西。

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

事实上，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。

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

这些桥梁是在造之前建造，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.

比这更古老岩石已经被造破坏或高度变形。

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

数百万年前，由于造力量，它被带到了地表。

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，因为它拥有造、表面液态水和富含氧气大气层。

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

造影响洋流流动，而洋流是全球气候模式重要驱动力。

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

正如我们在古地理和造课上学到，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，并在造理论建立过程中发挥了关键作用。

Without tectonics, slow bubbling leaks of lava from the interior of the planet can continue in one spot for a long time.

在没有造运动情况下，球内部缓慢冒出岩浆可以在一个地方持续很长一段时间。

C, climate change from plate tectonics.

C，造引起气候变化。
