So the bigger the crystals inside a geode, the older the geode is.

所以晶洞内的晶体越大，晶洞就越老。

She discovered it was filled with geodes.

废气的矿井中蕴藏着丰富的水晶矿石。

Our geodes look pretty small, so if there are crystals in them, they're probably small.

我们的晶洞看起来很小，所以如果里面有晶体，它们可能很小。

That geode is estimated to be at least 500,000 years old.

据估计，该晶洞至少有 50 万年的历史。

The problem with this is that the Corso artifact was found encased in a geode.

问题是 Corso 人工制品被发现包裹在一个晶洞中。

You'll need a sock, a hammer, safety glasses or goggles, and a safe place to break open your geodes.

你需要一只袜子、一把锤子、安全眼镜或护目镜，以及一个安全的地方来打开你的晶洞。

These have bigger crystals, so this geode must have been able to collect minerals longer than the other ones.

它们有更大的晶体，所以这个晶洞收集矿物的时间肯定比其他晶洞长。

We have three rocks that we think are geodes!

我们有三块我们认为是大地测量的岩石！

Thanks for learning about geodes with us!

感谢您与我们一起了解大地测量！

Finding one is exciting because it can take geodes thousands or even millions of years to form.

找到一个是令人兴奋的，因为它可能需要数千年甚至数百万年才能形成。
