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.

一些撞击引发了山作用，在月球表面形成了巨大的熔岩池，然后固化形成了玄武岩，也就是天在月球上看到的黑色斑点。

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

很可能是来自低温山——冷山作用；也即由水和氨组成而非熔岩喷涌的山。

These results suggest that geological activity and volcanism still play an active role in shaping the Martian surface.

这些发现表明，地质活动和山作用仍在积极塑造星表面。

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是山作用形成的。

These same volcanic forces also created Ethiopia's highlands.

这些相同的山作用 也造就了埃塞俄比亚高原。

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

山作用（对山活动过程的命名）塑造了整个世界。

The tectonic activity and volcanism help sustain life by stabilizing the global temperatures and the carbon cycle.

板块活动和山作用有助于维持生命，它通过稳定全球温度和碳循环来实现这一点。
