National Geographic: Mysteries Underground :: essays research papers

National Geographic Mysteries UndergroundThe video I reviewed was a National Geographic film called MysteriesUnderground. This video was about extraordinary sites on that point are to guess inunderground caves. You traveled along with cave explorers and got to see allthe beautiful untouched natural formations such as gypsum chandeliers, gnarledcalcite columns, and jewel-like lakes. It showed and talked about all thecareful proceders the cave explorers go by dint of. It also talked about how theformations were make over such a long time.I learned many interesting things that would never seem possible. Inthe worlds new most exotic ,Lechuguilla, cave there lied water so clean andclear that the cave explorers were forced to take all there clothes off beforethey swam acrossed it because the littlest filth from any clothing wouldcontaminate the pureness of the water. All the cave explorers are very cautiousas to what they touch or where they step because nigh of the crystallizing f ormationsare so fragile that the slightest vibration from a voice or a footstep couldruin millions of years of forming. In some parts of caves there are giant andvery smooth ice formations that must be slid down very carefully because if theyare not taken cautiously you get out pick up to much speed while sliding andfinally hit some kind of stone wall or something. unmatched lady was not carefulenough and boy did she pay. She was only a mile and a half or so in the caveand she broke her leg. It took near five days to get who to the surface ofthe cave where she could be attended to. Also I found out that caves were muchlarger then I had originally thought. The largest cave now, Mammoth Cave, isover 200 miles long. And if you are exploring a cave being miles and miles fromthe entrance it is very important that you be careful because if you establish yourleg that far from the entrance it would probably take months to get you outsafely. One safety precaution I learned was that when the explorers aretraveling through cold water they must make sure they dont get their upperbodywet because that will cause them to freeze and get many sicknesses that arecaused by the cold. One thing that I found interesting was that with thetechnology today you would think that we would have all the caves discovered andexplored. We arent close at all. In fact some caves have been being exploredfor years and there is still no end in sight.
