Once our entire Earth was made of hot gases.

曾经我们的整个地球都是由高温气体构成的。

The gases cooled into hot rock. A thin crust formed over the rock.

气体冷却成热岩石。 岩石上形成了一层薄薄的地壳。

Volcanoes spewed melted rock and steam from inside the Earth.

火山从地球内部喷出融化的岩石和蒸汽。

The steam formed clouds, then fell back to Earth as rain. The rain made oceans, rivers, and lakes.

蒸汽形成云，然后以雨的形式落回地球。 雨水形成了海洋、河流和湖泊。

The world we know was born because of volcanoes! Today, volcanoes still shape our world.

我们所知道的世界因为火山而诞生！今天，火山仍然塑造着我们的世界。
