The continental crust is higher than oceanic crust, so water flows down to fill those huge basins.

大陆地壳比海洋地壳要高，所以水会向下流入这些巨大的盆地。

The resulting recycled magmas form many different types of granite and granite-like rocks, which make up most of the Earth's continental crust.

由此产生的再循环岩浆形成了许多不同类型的花岗岩和花岗岩状岩石，它们构成了地球大陆地壳的大部分。

That is enough rock to explain the continental crust.

这足以用来解释地壳的形成。

On Earth, this recycling process usually happens at subduction zones, where the oceanic crust slides beneath the continental crust, warming as it goes down.

在地球上，这种循环过程通常发生在俯冲带，即海洋地壳滑落到大陆地壳之下，并在向下移动的过程中变暖。

It's denser than the continental crust but only a few kilometers thick.

它比大陆地壳更致密，但 只有几公里厚。

It’s denser than the continental crust but only a few kilometers thick.

它比大陆地壳更致密，但 只有几公里厚。

There are actually two types of crust on Earth: continental crust and oceanic crust.

大陆地壳和海洋地壳。

There are two types of crust on Earth: Oceanic crust, which is about five kilometers thick, and continental crust, which is a much beefier 30-50 kilometers thick.

一种是海洋地壳，约5千米厚；另一种是大陆地壳，约30至50千米厚。

While plate tectonics are the dominant mechanism for generating new continental crust today, in the distant past Earth's subsurface temperatures are widely thought to have been too hot to allow plates to form.

虽然板块构造是今天形成新的大陆地壳的主要机制，但在遥远的过去，人们普遍认为地球的地下温度太高，不能形成板块。
