Most likely this was from cryovolcanoes, cold volcanism; that is, volcanoes where water and ammonia take the place of lava there.

很可能是来自低温火山——冷火山作用；也即由水成而非熔岩喷涌的火山。

These same volcanic forces also created Ethiopia's highlands.

这些相同的火山作用 也造就埃塞俄比亚高原。

Volcanism, the name givento volcanic processes, really has shaped the world.

火山作用（我们对火山活动过程的命名）塑造世界。

The high level of radiation in the rocks implies that they are volcanic in origin.

【imply】这些岩石内的高辐射显示它们是火山作用形成的。

Some of these actually triggered volcanism, which created these huge pools of molten rock on the surface, which then solidified to form a rock called basalt, which are the dark splodges that we can see on the moon today.

一些撞击引发火山作用，在月球表面形成巨大的熔岩池，然后固化形成玄武岩，也就是我们今天在月球上看到的黑色斑点。
