You all saw the video, it is a very scary sight to see. Whole clumps of trees getting literally swallowed by a massive sinkhole. I posed a hypothetical question yesterday saying "Where did the trees go???".... Well in a nutshell, they fell almost 750 feet down!!! So what is letting this happen? What causes a sinkhole and in this case what makes a GIANT sinkhole??
You have seen them in many places, the Earth just opens up and boom, a massive hole forms. Most of the time it is caused by something happening underground like a small underground stream, or a small underground rift that allows water to flow. This will carry all the Earth away under the ground and eventually the ground above caves in, creating a sinkhole. The can range from 2 feet to several hundred feet!
