This week in class we watched two movies about magma and volcanoes. One was rather ridiculous and the other was more of a documentary, however, I managed to learn a great deal from both of them. Some things I learned in the movie “Magma” is that shield volcanoes errupt with oozing lava, 33% of all the lava on earth comes from the volcanoes from Iceland, the rotten egg smell from the inside of the volcano is the hydrogen sulfide gas, exodus is the ideal that all the volcanoes on earth will erupt at once due to the expansion of the inner core, lava tubes occur in more low viscous volcanoes, and yellowstone is caldera. In contrast to that movie, we watched a documentary about the world’s deadliest volcanoes. Some things I learned from this video are: volcanoes explode with 25 times the force of a hydrogen bomb, Mount Saint Helens and Mount Venere are considered the deadliest volcanoes in the U.S., and the volcano outside of Mexico City could be the deadliest volcano in the world because it could potentially kill all ten million inhabitants.
Also, this week I began to focus more on the paper that we have for class. My topic is “What minerals are used in construction and how does the use of these minerals affect everyday life.” I began by researching some of the basic everday minerals that most people are aware of when they see them, then I went on to research some of the lesser know minerals that are still essential for us to do things such as live, drive to work, and be comfortable with our everday living routines. The most common mineral I looked at was aluminum, which is the most abundant metallic element in the Earth’s crust, as we learned in class. It is used in automobiles and airplanes, as well as bottle caps and cans, and also builings and electrical appliances. While Aluminum provides a large component for cars, basalt is a major component in the asphalt we drive on. The mineral Barium is commonly used in paints, rubbers, and plastics, which could also go into auto production. Minerals more commonly found in the housing industry are: Boron (glass, ceramics, fiberglass, soaps, and detergents), Copper (eletric cables and wires, switches, pumbing, heating, machinery equiptment, coins, and jewelry), Feldspar ( glass and ceramics, pottery, porcelain, cement, glue, fertilizer, and tar in roofing), Garnet (eletricals, ceramics, glass, jewelry, abrasions in furniture), Molybdenum (stainless steel), Quartz (pressure gages, oscillators, resonators, and wave stabilizers, plus glass, paints, abrasives, refractories, and precision instruments), Sandstone (concrete, building stone), Silver (photography, eletrical products, silverware, electroplated wire, jewelry, coins, and brazing alloys), Talc (paper), Trona (fiberglass, specialty glass, flat glass), Gypsum (industrial and builing plaster, wall board, cement), andLead (batteries, construction, ammunition, television tubes, ceramics, weights, containers, tubes). There are hundreds of other hidden minerals that most people wouln’t recognize are there, but the truth is all of these minerals make up everything that we touch, feel, breath, or use in everyday life.
