Museum of Natural History!

The trip to the museum of natural history was great! i haven't been there since i was like in third grade. It was really interesting and the animals and humans in there looked so real. Pretty crazy..\
Here are some of the things that i learned at the Museum Of Natural History. Venus and earth are about the saem size and probably started out with similar atmospheres, But now the aitmospheres are very differnt... The amouunt of carbon dioxide in the atmoaphere is related to global temperature- as the earth warms. Co2 increases . Vice versa. Measuring co2 in ice cores provides a record of atmospjeric co2 variation over thousands of years- from one glacial period t another. By tracking the
natural variablity of co2. Scientists havre discovered that the recent rise in atmosphere co2 has ben casued by human activities. Carbon dioxide and global warming... Glacial ice records the the climate of past ages.. The composition of the ice itself and of the air bubbles and dust trapped in it record changes in temperature. Humidity. Atmospheric . Circulation. Volcanic activity, extents of sea ice, and even atmosheric pollution by human activity. Greenland how ice burgs are melting because of global warming. Greenland melts and sea level rise and soon or later it wil gulf land... Pollution from human activity. The burning of coals releases nitrogen and sulfur compund sinto the atmosphere. They show up as higher concentrations of nitrate and sulfate compunds in ice. Average increases in these pollutants became evident in ice core layers beggining in the late 19th century.
Global warming-the amount od carbon dioxide in ther atmosphere has increases due to the extensive burning of fossil fuels. Which started with the industrial revoltuion around 1850. Since then global temperature has aslso increases. Because carbon dioxide is a greeb gas.
Scientists believe it is partyle reponsible for this warming. Discovering fossil detective. There were many media forms and presentations in the Museum Of Natural History. They displayed things through mini films, exhibits, pictures and there were workers that were explaining the exhibits. One media form was a mini video presentation i saw about global warming. There were many effects and cinematic elements that really helped explain how green land ice lands were melting because of global warming. The video showed how greenland ice was melting over the years and how risky this can be for us. The presentation was great and i learned so much from a 3 min presentation. The pictures in the exhibit related to the film. There cinematic sensibility. Overall the Museum Of Natural History was a great trip and there is so much history and information that is very important in there. I learned so much at the Museum.
