Geology: The Grand Canyon
Geology started out with the simple curiosity of the earth, its rocks, how and when they formed. “William Strata Smith first recognized in the early 1800s that the fossil record had systematically changed through time.” This lead scientists, namely geologists from all over the world to make divisions of geological time known as a relative time scale. In order to get a generalized date they placed rocks and fossils into eras and periods. With a relative time scale, scientists were able to work together to establish a timeline they could use to categorize the age in which the rock or fossils existed.
John Wesley Powell discovered the Grand Canyon on one of his expeditions and called it “the greatest exposure of rock record on the content.

    Many people were not aware of Arizona's Canyon until 1869, when John Wesley Powell became the first to travel its full length by boat. In 1871 Powell made a second trip accompanied by the young artist Frederick Dellenbaugh. His third trip was in 1873, when he introduced the Grand Canyon to landscape artist Thomas Moran, who portrayed its grandeur to the public. Moran work was to compel President Theodore Roosevelt to declare the site a national monument.…

    Chaco Canyon is located in northwestern New Mexico. Around 700 they started building rectangular houses above the ground. There was higher rainfall and higher groundwater levels and this caused an increase in population. What was so remarkable about this period was the Chaco phenomenon, which is the construction of fourteen Great houses in Chaco Canyon. These houses were multistory, and made from stone-and-timber pueblos. One of the houses, known as Pueblo Bonito, had more than six hundred rooms, forty ritual enclosures and it was as high as five stories. Large caches of rich ceremonial artifacts have been discovered and so it is believed that it served as ceremonial functions.…

    The rock cycle is something that a lot of people know. There are a lot of different versions. Some are more complicated than others(OI). The rock cycle can take thousands of years to complete(OI)! Every rock can turn into another rock from every stage(Doc.1). Geology is not just studying boring rocks. There is a lot more to it. You can study rocks to find out how old the rock is or even how old the earth is. You could be the person to find out how long ago a dinosaur by what rock the bones were in. Or maybe you find a fossil of a new type of animal and the rocks can tell you when it lived. Rocks can be a whole lot more exciting than you ever thought.…

    The United States Geological Survey indicates that there is considerable amount of evidence that the earth is approximately 4.5 through 4.6 billion years old (The Age of the Earth, 2014). Many other old-earth advocates also believe that the earth is roughly the same age. One method of determining the age of various rocks and minerals found on the earth is the radiometric time scale (Radiometric Time Scale, 2001). “Radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock '” (Woolf, J., n.d.). By using this radiometric dating process, scientists have been able to determine the age of rocks and other items found on the earth that vary from just over two thousand years to over 3.6 billion years old (Radiometric Time Scale, 2001).…

    Colorado is located in the mid western part of the United States, bordered by Wyoming, Utah, Arizona, New Mexico, Oklahoma, Kansas and Nebraska. “Being located as a mid-latitude interior continental state (and having the highest average elevation in the United States), combined with complex topography, results in dramatic climate differences from place to place and from year to year. From the Great Plains of eastern Colorado to the high peaks of the Rockies and the Continental Divide, to the valleys, canyons and plateaus of western Colorado, the various climates are each very different.” (CCC) The population of Colorado as a whole is 5,029,196 as of a 2010 Census estimate and the capital is Denver. Other big cities consist of Colorado Springs, Aurora, and Fort Collins.…

    I recently backpacked 32 miles through the Grand Canyon National Park over spring break. My trip leader told me, “Sorry I made you guys pack so many warm jackets and clothes, its usually not in the 90’s during this time of year”. Just like that I thought to myself, I could have had a lighter pack but I also thought about how global warming is real and its everywhere, even in the vastest lands. Like astronomer Lucianne Walkowicz said and I mentioned in my previous paper, “the more you look for planets like Earth, the more you appreciate our own planet” I came to a realization just buy exploring the Grand Canyon how important the rule of leaving no trace behind really is. The Grand Canyon National Park, as well as other parks really enforce this…

    Age of the Earth

    • 560 Words
    • 3 Pages

    Scientists have settled on the age of the earth of about 4.6 billion years as a result of research started almost 50 years ago. This conclusion was based upon carefully designed and conducted experiments that compared the ratios in rock samples of parent elements to daughter elements ( some of which would have been from radioactive decay of the parent, some of which may have been present in the sample at the time of formation). Since radioactive decay is known to occur at a constant rate, the age of a rock can be determined from the ratio of the parent element to the daughter element. The concerns about these dating methods were exactly the same that creationists continue to raise - presence of the daughter element at the time the rock was formed and possible loss / gain of either the parent or daughter element at some point in the history of the rock. For this reason, the tests were designed to account for those possibilities.…
