Antarctica Research Paper

The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.

Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004.

People might wonder some basic geography of Mount Everest. The first aspect of the geography of mount everest is the elevation. First of all it is the talled above ground mountain with a whopping elevation of 29,035 said Rosenberg. Mooney said that some glaciers are melting up to 8,850 meters up witch is equal to 29,035 feet up. At Everest's highest point, you are breathing in a third of the amount of oxygen you would normally breathe due to the atmospheric pressure (Bromwich).

Sedimentary rocks interpret dinosaur habitats through encased environmental structures of the past. Through sedimentary rocks, paleoecologists’ can examine the arranged formation of sedimentary structures to specify what type of environment the dinosaurs’ lived in. An example of a specific sedimentary rock structure can be seen through formed weathering and ripple marks by how wind and sand formed distinct patterns in the past layered sediment. These arrangements provide interpretations on the structure of the sediment and the habitat of encased fossils, through modern day comparisons

Proof of volcanic activity related to the break-up of Australia and Antarctica is seen at Bunbury, which is located 150km south of Perth, at the point where the basalt is of early Cretaceous, also on the middle Jurassic Kangaroo Island. However, evidence of Cenozoic eruptions is only seen in Eastern Highland. All through the Cenozoic, hot spot volcanic event transpire (Sutherland et al., 1985). Most of these events follow the Miocene (Stephenson et al., 1980) with recent eruptions close to the southern and northern margin of volcanic zone at southeast of South Australia and north Queensland respectively.

Mount Baw Baw is a mountain that belongs to a Great Dividing Range, situated in Victoria, Australia. Mount Baw Baw Alpine Resort is an unincorporated range of Victoria which is part of the Shire of Baw.

The reading passage proposes three theories which support the idea that a dinosaur which is called edmontosaurus survived in the winter by migrating to the south, the more hospitable region than the extremely cold in the North Slope. However, the professor in the listening respectively contradicts each theory in the reading passage by using strong evidence as support.

4. Choose one of the geological periods listed in figure 3.8 and find out all you can about it. How are rock formations from that period identified? What are its most characteristic fossils? Where are the best samples of rock from your chosen period?

In order to find evidence of the transition from fish to land animals, the author and his colleagues chose to focus on 375 million year old rocks. In 2004, they studied sedimentary rock on Ellesmere Island in Canada’s Arctic as they thought that the rocks there would be exposed and untouched by humans, which would be ideal for fossil excavations. They studied sedimentary rocks (limestone, sandstone, siltstone and shales) because these

In a study published in Cretaceous Research and conducted in October 2012 by Anthony R. Fiorillo, Thomas L. Adams and Yoshitsugu Kobayashi, evidence of dinosaurs was based on the finding of an unnamed nonmarine sedimentary package of rocks. Found in the Wrangellia Terrane and considered to be Cretaceous age, the rocks are light colored with medium grey shales and indicate a bounty of horsetails, ferns and gymnosperm wood.

At some 18,000 ft, the base-to-peak rise is the largest of any mountain situated entirely above sea level. It has a topographic prominence of 20,156 feet and a topographic isolation of 4,629 miles. Located in the Alaska Range, in the interior of Alaska, Denali is the centerpiece of Denali National Park. The Koyukon people called it Denali for centuries.

There are two peaks, the tallest reaching 20,310 feet above sea level.(Pletcher) The peaks can only be seen for a few minutes here and there, because the rest of the time they are covered by clouds. At the top there are permanent ice fields that feed down into huge rivers. A study showed that Mount Denali is the second tallest mountain in the world if measured from base to peak. It is taller than Everest if measured from base to peak and second to an enormous underwater mountain. It is 18,000 feet from base to peak. (Zimmerman) It is the third highest when measured from sea level, making it one of the seven
