Boundary

Question: Describe in detail the three theories that were the predecessors to plate tectonic theory. Provide evidence of how features of the surface support the current, theory of plate tectonics describing the ways the tectonic plates interact and the result of their interactions. The Continental Drift Theory The Continental Drift can help the surface support the current by plowing through ocean basins. It also did not include seafloor spreading or subduction. So, that did not cause an…

Plate tectonics is a theory about how the plates are constantly moving on top of a layer of magma that is constantly taking in old crust to recycle it this constant movement causes earthquakes, tsunamis and other geological events. The movement of the Pacific and North American plates cause the old sea floor to be replaced by the now wider North American plate. Also with the movement the continental plate was stretched as the Pacific plate pulled the continental plate to the northwest which…

Boundary Violations The process of creating a true relationship requires setting boundaries. In order to avoid losing ourselves, or because we fear losing or upsetting our loved one, we often over commit to rigid boundaries or fail to have them at all. Which explains why some relationships are in a constant boundary dance that swings between doormat and narcissistic syndromes. The doormat is always accommodating, ever flexible and always nice. They are the self-sacrificing loser in most…

certain spots of western South America. I believe that this particular formation will continue to form more and more volcanos as time goes by. This would most likely happen because of the subduction boundary going on (South American plate is continental, Nazca Plate is oceanic), and if the Nazca boundary continues to push underneath the South American one, it will cause the plate to liquify, which accordingly would cause eruptions. Because of the eruptions, the volcano would continue…

beside something.” In society, borders act as geographic boundaries, but also as boundaries separating people, culture, and ideologies. In the United States of America, borders act as boundaries between both states and cultures. Additionally, boundaries in America stand between itself, and other countries, specifically Mexico. Borderlands, according to its definition, are districts or land surrounded and separated by boundaries. These boundaries, no matter how physical or literal serve the…

subduction, mid-ocean ridge, and ocean trench and island arc. Subduction is when two tectonic plate’s convergent boundaries come crashing together resulting in one going below the other. This results in the bottom plate to sink into the mantle. Mid-ocean ridge is an underwater mountain ridge that forms when convection currents causes magma to rise where two tectonic plates meet at a divergent boundary. Ocean trench are long narrow depressions on the sea floor as a result most ocean trenches…

Dear US Geological Survey, I think that you should accept Alfred Wegener’s Theory of Continental Drift. There is a large amount of realistic evidence to prove that this theory did occur. Wegener’s theory is that all seven continents were once joined into a supercontinent called Pangaea. He believes that after continents were in that supercontinent, they gradually moved apart over more than a hundred years ago and will continue to move in the future. This Theory of Continental Drift is supported…

4.2.5. The Fantale geothermal prospect area The Fantale geothermal prospect is characterized by recent summit felsic lava, caldera collapse, extrusions in the caldera bottom and widespread fumarolic activity, signifying thereby the existence of a shallow magma chamber (Tekelemariam and Beyene, 2005). Active tensional tectonics form fissures up to 2m near the volcanic complex. From the area ground water discharge to the system is guaranteed by the proximity of the area to the western escarpment.…

Mt. Pinatubo, Philippines: Impacts and Human Actions The stratovolcano Mount Pinatubo began showing signs of erupting on the 15th of July 1991. Through a series of events Mt. Pinatubo erupted and effected the surrounding areas. Throughout this paper will be discussed the impacts, including primary and secondary, along with impacts changed by humans. Mount Pinatubo eruption was the second largest eruption in the 20th century, making it have many impacts not only locally but globally. Mount…

The Western Cordillera is found standing along the western edge of the continent. Made of ranges and ranges of mountains separated by occasional plateaus and valleys. Many provinces found in this region are British Columbia, Yukon Territories, Southwest Alberta, and parts of Northwest Territories. The mountain ranges found here are not as old as the other regions, as they are not yet rounded hills. These mountains occurred when the North American and Pacific plates collided, that spans…
