Observing The Mega Picture And Paradigm Shift

Although there are other volcanic events that don’t prove that the tectonic theory is valid. For example The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world's active and dormant volcanoes. This huge ring of volcanic and seismic (earthquake) activity was noticed and described before the invention of the theory of plate tectonics theory. Also without movement at the boundaries around the Pacific, volcanoes such as Mt St Helens would simply not exist, as they would have no fuel caused by the subduction of an oceanic plate under a continental plate.

Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks)

The theory of plate tectonics was first developed by Alfred Wegener. He concluded that the continents seem to have a similar shape and could potentially fit together. This suggested that they were at one time joined together as part of 2 super continents called Gondwanaland and Laurasia was in the north. This theory was said to be proven by the discovery of fossilised remains of a mesosaurus that were found on the coasts of Brazil and Gabon. Sea floor spreading is another theory that supports the idea of plate tectonics; this theory discovered that rock is being formed under the ocean as a new sea floor. Sea floor spreading was shown in the Atlantic, where it is believed the Eurasian and North American plates are moving apart on a

Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt. (Pitman, W.C., 2007)

To support the theory of continental drift is through topography, surveying the floors of oceans, charts of rock magnetism, and statistics on rock ages (Trefil & Hazen, 2010). At one time scientist believed that the deep ocean floors were flat; accumulating the sediment that progressively wore away from the prehistoric landmasses (Trefil & Hazen, 2010). However, they discovered steep-walled valleys and elevated highlands. This was evidences that just as the continents are transformed and are active, so to is the seafloor (Trefil & Hazen, 2010). The Mid- Atlantic Ridge, positioned in the central part of the Atlantic Ocean, is recorded to be the longest mountain range on this planet. Volcanoes, lava flow, and earthquakes are a source of

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

A paradigm is defined as how you perceive or see something. Therefore, a paradigm shift is when your perception of something is changed or challenged. For many characters in the movie Remember the Titans, the struggle of integration and football challenges their thoughts on racial segregation. While many of the characters don't agree with the idea of integration and believe that they are superior to the rest, paradigm shifts happen for most every one of the characters. Throughout the movie we see that both adults, teens, and children have paradigms of others, themselves, and relationships.

The forming of the geologic features go way back to starting with the beginning of North America millions of years ago. The land that is now known as Eastern California, was covered by a shallow sea. North America was slowly being pushed westward and oceanic crust was being pushed onto the side and being pulled underneath the continent. After continuous repetition, this accretionary wedge formed. This is when some of the crust pushes up onto the edge of the

However, if you travel away from the ridges you will encounter rocks with reverse polarity and then rocks of normal polarity which are followed by reverse polarity rocks, etc. Vine and Matthews observed that there were symmetrical bands of rocks with similar polarities on each side of every mid-ocean ridge. They hypothesized that the reverse polarized rocks formed at the ridges during the geologic past when the earth's magnetic field had reverse polarization. Their work provided rather elegant proof that the seafloor spreading actually occurs.

Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today” (Briney). Geology defines “plate” as a large slab of solid rock, and “tectonics” is part of the Greek root word for “to build.” Together the words define how the Earth’s surface is built up of moving plates. The theory of plate tectonics dictates that individual plates, broken down into large and small sections of rock, form Earth’s lithosphere. These fragmented bodies of rock move along each other atop the Earth’s liquid lower mantle to create the plate boundaries that have shaped Earth’s landscape. Plate tectonics originated from meteorologist Alfred Wegener’s theory, developed in the early 20th century. In 1912, he realized that the east coast of South America and the west coast of Africa appeared to piece together like a jigsaw puzzle. He further examined the globe and deduced that all of Earth’s continents could somehow be assembled together and proposed the idea that the continents had once been linked in a single supercontinent called Pangaea. To explain today’s position of the continents, Wegener theorized that they began to drift apart approximately 300 million years ago. This theory

Continental drift was a theory offered by Alfred Wegener in 1912 that hypothesized that all the continents at one time fit together as one land mass. Wegener, explained that the ends of each continent could fit together like a puzzle and that over time the continents drifted apart. "The model explained why the same types of fossils occur in sedimentary rock on both sides of the vast Atlantic Ocean" (Star, 2008, pg. 250), in other words allopatric speciation. Wegener's theory did not have a supporting geological mechanism. Many years later and advances in technology brought about the plate tectonics theory. Essentially it says:

Refer to the images above. Discuss in detail the two pieces of additional evidence that supported Wegener’s theory, now known as the theory of plate tectonics.

“When you change the way you look at things. The things you look at change.”-Wayne Dyer an American philosopher. What are paradigms and paradigms shift? Well first of they can be seen everywhere but, a paradigm is a way someone sees something, their point of view or frame of reference. A paradigm shift is looking at something from a different perspective, it's like putting on a new pair of glasses. It’s also a fundamental change in approach or assumption. Paradigms can be anything like places people and even things The three stories Amir, Fairy Tale and the last spin are all great examples of both paradigms, paradigms shifts and how they all come together.

The earth has been through a lot of changes throughout time. It used to be thought that the continents were locked in their positions and couldn’t move, but in 1915 Alfred Wagner came up with a theory about continental drift (Tarbuck and Lutgens, 2015). While unsure of the process that happened at the time, Wagner also came up with the idea that all the continents in existence today were once all connected as one giant continent known as Pangea. This idea is supported by the findings of similar rocks or fossils in multiple locations separated by large water bodies. Thanks to more tools and funding, the oceanic ridge system was found and by 1968, the theory of plate tectonics was introduced (Tarbuck and Lutgens, 2015). This theory

Scientist are struggling to come up with a widely accepted model that will explain the role of non-vertical strike-slip fault segments, crustal movement and deformation within Pacific –North American plate boundary. Multiple methods of analysis are being used; some of which are described below.
