List and describe the six different periods into which the Paleozoic Era is divided

The first period in the Paleozoic Era was the Cambrian Period. During this period there was a sudden explosion of life on earth. The climate of the Cambrian Period was relatively cold at first, but then started to gradually warm up. Halfway through this period life started to go extinct.

The second period in the Paleozoic Era was the Ordovician Period. During this time, life underwater went through some tremendous changes. Also, a variety of marine life flourished also plants were beginning to appear on land also most of the world's land masses came together to form the super continent of Gondwana. Then Gondwana drifted south during this time, then finally settled in the Southern Hemisphere. The climate was mostly warm and humid and during this time sea levels were rising. At the end of the Ordovician period there was a mass extinction.

The third period in the Paleozoic Era was the Silurian Period. During this time sea levels were rising more and continental land masses were low. Also, having a warm climate caused ice glaciers to melt. Gondwana was still located in the southern hemisphere, but it then stretched to the equator. The seas in the Silurian Period were warm and shallow because of that, many life forms were able to be

    Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These compositions ranged from alkaline to mafic to rhyolitic based on their interactions as they made their way to the surface with country rock.…

    The Sierra Nevada is the longest mountain range in America and it lies partially within the parks. Along this range lies Mt. Whitney, at an elevated height of 14,491 feet and considered the tallest mountain within the lower United States. In Sequoia National Park, resides another prominent ridge of mountains called the Great Western Divide and it has been posed as the rival of the Sierran Crest. The topography and its gradual formation was the result of the uplift of the southern portion of the Sierra block over an elevation of 8,000 feet during the Plio-Pleistocene time (Konigsmark 2002).…

    The Paleolithic and Neolithic eras mark the beginnings of art, agriculture, and “civilized” society in humans. The Paleolithic era made up the first part of the Stone Age and lasted over two million years, and came to an end after the end of the last Ice Age. The humans living during this time lived primarily as hunter-gatherers and depended on the land for all resources. In a time prior to practices such as farming and domestication, the societies of this time lived off a combination of wild game and plants gathered from the forests.…

    It is interpreted to extend southwards into the United States below the Williston basin and extends northeast into Nunavut and northern Quebec wrapping around the Archean Superior craton (Ansdell, 2005). The THO is the end result of the closure of the Manikewan Ocean (Stauffer, 1984) which resulted in the formation juvenile crust which was eventually accreted onto the Archean Superior and Hearne cratons as well as a number of smaller cratons including the Sask Craton (Lewry et al. ,1994). The THO preserves a relatively complete tectonostratigraphic evolutionary history including evidence for rifting (ca. 2450-1950 Ma), the formation of oceanic crust (ca. 2000-1800 Ma), and sedimentary assemblages deposited along continental margins and younger (1880-1830 Ma) collisional and foredeep basins (Ansdell, 2005). The southwest exposed portion of the THO in the Canadian Shield is known as the Manitoba – Saskatchewan Trans-Hudson Orogen (MS-THO).…

    The Cambrian Period was an era filled with a massive explosion of a variety of animals and ecosystems. It was a time where super continent Pannotia no longer existed. During this time period, North America remained above water and was eroded by running water. North American was also on the equator which meant warm climate. The continents were oriented very differently, the east coast of North America faced the south.…

    New fossil evidence suggests that dinosaurs originated early in the Middle Triassic time period, during the recovery of life from the Permian-Triassic mass extinction (Benton et al. 2014). Transient episodes of unusually warm and wet conditions, interrupting long periods of cool and dry conditions, may have played a role in mass extinctions and long-term evolutionary trends (Retallack 2013). Although the Permo-Triassic mass extinction wiped out nearly 85% of species, the crises marked the beginning of the Mesozoic Era, a time period often associated with the Age of Reptiles (Benton et al. 2014). The Permo-Triassic extinction was likely a consequence of massive volcanic activity and consequent severe global warming, acid rain and ocean anoxia…
