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.

果是这的话，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，看起来发生时比她在萨德伯里看到的撞击时得多。

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。

And so they are therefore just more fertile and easier to grow crops in than New Zealand where volcanism is more dormant and rarely even happens.

因此，这些土地比新西兰的土地更肥沃，更容易种植庄稼，新西兰的火山活动休眠得更多，甚至很少发生。

While active volcanism introduces some amounts of minerals to the North Island soils, these eruptions don't really happen that often and they're usually pretty minor events.

虽然活跃的火山活动给北岛的土壤带来了一些矿物质，但这些喷发并不经常发生，通常是相当小概率的事件。

" What you see at Compton-Belkovich is sort of a surface expression of something a lot bigger underneath." Volcanism is evident elsewhere on the moon.

“你在康普顿贝尔科维奇所看到的，是某种更深层事物的表面表现。”月球其他地方的火山活动也很明显。

The evidence for recent volcanism " changes our understanding in the sense that now we will probably start focusing on catching Venus in the act of erupting" .

最近火山活动的证据“在某种意义上改变了我们的理解现在我们可能会开始专注于捕捉正在喷发的金星”。

Able to drill at over 8,000 meters (26,000 feet) beneath the surface of the sea, researchers collected previously unreached sediments to try and reconstruct the history of volcanism in the area.

研究人员能够在海面下超过8000米（26000英尺）的地方钻探，收集以前未获得的沉积物，试图重建该地区的火山活动历史。

Natural processes, such as volcanism, chemical weathering of rocks, and the burial of organic matter, can cause huge changes in carbon dioxide when they continue for millions of years.

自然过程，火山活动、岩石的化学风化和有机物的掩埋，在持续数百万年时会起二氧化碳的巨大变化。

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.

一些撞击发了火山作用，在月球表面形成了巨大的熔岩池，然后固化形成了玄武岩，也就是我们今天在月球上看到的黑色斑点。
