No one knows yet exactly how the impact could have sparked a prolonged episode of volcanism.

目前没有人确切知道撞击是如何引发长期火山活动的。

Venus was geologically dead, making the Earth the only rocky planet with active volcanism.

金星在地质上已经死亡，使地球成为唯一具有活跃火山活动的岩石行星。

C, volcanism putting more carbon dioxide into the atmosphere.

C，火山活动将更多的二氧化碳排放到大气中。

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）塑造了整个世界。

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；也即由水和氨组成而非熔岩喷涌的火山。

If that's the case, volcanism could very well be the root cause of Venus' thick cloud cover.

如果是这样的话，火山活动很有可能是造成金星厚云盖的根本原因。

Massive volcanism and falling sea levels might have forced them to extinction, even if the asteroid had missed.

频繁的火山活动和海平面下降也迫使它们走向灭亡，即使小行星没有碰撞地球。

We believe that the extinction may have been related to intense volcanism during the initial breakup of Pangea.

我们认为，这次灭绝可能与盘古大陆最初分裂期间的强烈火山活动有关。

In many spots in the solar system it looks like volcanism happened much longer after the impact than what she saw at Sudbury.

太阳系中的许多地方都有火山活动，看起来发生时间比她在萨德伯里看到的撞击时间要晚得多。

Suzanne Smrekar of NASA's Jet Propulsion Laboratory in Pasadena, California, and her colleagues have found signs of relatively recent volcanism.

美国宇航局位于加利福尼亚州帕萨迪纳的喷气推进实验室的 Suzanne Smrekar 和她的同事发现了相对较新的火山活动迹象。
