15 BIGGEST Holes in the Earth

Our planet’s surface is covered in peaks and troughs that have been formed naturally over thousands, or millions of years… and artificially by human activity in recent times. The surface layer, known as the crust, is so thick that there’s no known cavity that burrows through it to reach what’s beneath, but there’s certainly plenty of holes that reach far down to extraordinary depths, or cover such a wide area that it’s almost impossible to know you’re actually in it. It’s time to go deeper than ever before, as we explore the top 15 biggest holes in the earth. #top15 Several segments are licensed under creative commons https://creativecommons.org/licenses/by/3.0/legalcode For more video information, please visit our website.
