Summary
Have you ever seen a sinkhole? These are spots in the Earth’s surface where the ground has collapsed and formed a hole. Sometimes they can be more than a hundred feet deep! But how do sinkholes form? We asked geologist Hazel Barton to help us find the answer.
Got a question that’s a real hole in one? Send it to us at BrainsOn.org/contact, and we’ll help dig up the answer!
