Hey there! Welcome to Life Noggin.
大家好！欢迎来到脑洞大开的生命奇想。
My animator was telling me that in the human world the Earth tried to eat his car!
我的动画师告诉我，在你们人类的世界里，地球想吃掉他的车！
I was super confused at first, but then I learned that he was talking about these sometimes scary things called sinkholes.
一开始我非常困惑，但后来我知道他说的是天坑那种可怕的东西。
It's often joked that sinkholes are when the Earth tries to gobble us up, but it had me wondering, just what are sinkholes and how do they even form?
人们常开玩笑说，地球想吞噬我们的时候，天坑就会出现。但这让我很纳闷，天坑到底是什么，它们是如何形成的？
Sinkholes are depressions or pits in the landscape that can have steep, rocky sides, look bowl-shaped, and even be homes to a small lake.
天坑是地表的洼地或坑，侧面陡峭、凹凸不平，形状像碗，底部可能有一个小湖。
Their size can vary greatly and while they usually form gradually, they can also collapse suddenly. Mother Earth can be impatient when she's hungry.
它们的大小会有很大的差异，虽然它们通常是逐渐形成的，但也可能突然崩塌。地球母亲在饥饿的时候会不耐烦。
Sinkholes can most notably be found in karst terrains, which is a term for places throughout the world whose features are largely influenced by underground drainage.
天坑最常见于卡斯特地形，卡斯特地形是指地貌主要受地下水系统影响的地方。
In addition to sinkholes, karst terrains of the world are also often categorized by features like caves, sinking streams, and springs.
除了天坑，喀斯特地形的特色地貌还有洞穴、伏流和泉水。
Sinkholes can form when water gathers in an area and isn't drained out externally.
当水聚集在一个区域，无法外排时，就可能形成天坑。
As the groundwater drains below the surface, it can dissolve the underlying rock.
由于地下水在地表以下流动，它可以溶解地下的岩石。
This is especially true in places where the earth is made of rocks like salt, limestone, or dolomite.
在土壤由盐岩石、石灰石或白云石等构成的地方，情况尤其如此。
Going further into what causes them, one recent study looking at a karst region in Spain found that sinkhole activity is intensified during drought periods.
为探究其原因，在西班牙喀斯特地区最近进行了一项研究。研究发现，在干旱期间，天坑活动加剧。
Since some scientists believe that periods of drought will become more common due to climate change, this could mean that greater rates of sinkholes could be an additional side effect of our changing climate.
一些科学家认为，由于气候变化，干旱期将变得更加频繁，因此这可能意味着地天坑活动愈加频繁，成为气候变化的另一个副作用。
Climate change is obviously important if the earth is eating us!
如果地球正在吞噬我们，气候变化显然很重要！
Now, it can be pretty scary to think that the Earth might try and swallow you and your possessions, but there can be warning signs for when a sinkhole might show up.
现在，一想到地球可能会打算吞噬你和你的财产，你就会感到非常害怕，但是天坑出现时，可能会有一些警告信号。
Leaning fences or trees are common appearances for the early signs of a sinkhole, along with cracks appearing in structures over the sinkhole and even wilting vegetation.
篱笆或树木变歪是常见的天坑早期迹象，天坑上方的建筑还会出现裂缝，植被甚至会枯萎。
Keep a lookout for these signs, especially if you're in an area prone to sinkholes. I always want my friends to stay safe!
注意观察这些迹象，尤其是如果你生活在天坑多发的地方。我希望我的朋友们平平安安！
