Like all sink holes, it was made by water eroding the rock beneath.

就像所有下沉的洞穴，它也是由于水侵蚀了下方的岩石所造成的。

The marine sink hole is almost 1,000 feet across and more than 400 feet deep.

这个海沟直径近1000英尺，深度超过400英尺。

The giant sink hole known as the Great Blue Hole is located nearest to what country?

这个被称为“大蓝洞”的水下巨坑离哪个国家最近？

The sink hole had cut away, or eroded, the front limbs.

下沉孔已经切掉或侵蚀了前肢。

Apparently what had happened, was many years ago, a sink hole cut through the badlands and this particular level.

显然发生的事情是多年前发生的，一个水坑穿过荒地和这个特殊的水平面。

In fact, it had cut right to the edge of the skull, and if it had continued cutting, before it got filled in, that sink hole would have eroded the skull away too.

事实上，它已经切到了头骨的边缘，如果它继续切割，在它被填满之前，那个下沉的洞也会把头骨侵蚀掉。

So, there were two chances this skull was going to be destroyed, but we were very lucky in that this skull was sitting exactly between the sink hole, and the edge of the hill.

所以，这个头骨有两次可能会被摧毁，但我们非常幸运，因为这个头骨恰好位于下沉洞和山的边缘之间。

And a sink hole is a like a cave that transmits water, and the water of course, erodes all the sediments around and the sink hole is like a well that goes deep into the cliff, well down below.

而沉洞就像一个输水的洞穴，水当然会侵蚀周围所有的沉积物，而沉洞就像一口井，深入悬崖，在下面。

The skeleton stretched between the sink hole and the edge of the hill and went back into the hill side, but we wouldn't have found that either if, in fact, that skull had not been eroding out slightly.

骷髅在水坑和山边之间伸展，然后回到山边，但事实上，如果那个头骨没有被轻微侵蚀，我们也不会发现。
