Are Earth's Tectonic Plates As Strong As They Were?

In conclusion the recent conception and development of plate tectonic theory has greatly aided our understanding of the distribution of seismic events. We now understand that there is a correlation between earthquakes/volcanoes locations and their proximity to a plate boundary plates are continually moving and earthquakes and volcanoes are found along these boundaries. Exceptions to this rule such as Hawaii also help prove tectonic theory due to their unique creation. Whilst this has helped our understanding we also recognise the fact those in LEDCs with poor access to education are unaware of plate tectonic theory so they cannot understand the hazards that some countries face, nor have the means to mitigate against them thus worsening the

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)

Over time, Earth’s process had to have changed at some point. The Earth’s changing process hasn’t just effected the landforms and natural features, but also the populations organisms living here. These drastic processes have caused landform changes, climate changes, and natural disasters.

For millions of years the Earth has experienced geologic catastrophes. Since the existence of Theia itself, the Earth’s crust has been formed, deformed, and even demolished. The crust has never been a completed masterpiece due to this. Why is this? The most recent physical changes were caused by the theory of plate tectonics and earth’s crust displacement. Plate tectonics and its movement resulted in our continents drifting across the earth’s surface, and the creation of mountain belts, volcanoes, and the faults of today’s Earth.

Some scientists know that tectonic plates have moved over time because of California’s changes over time. Scientists have provided us with the evidence in multiple ways.

Firstly, plate tectonics was not formed exclusively from induction which differentiates “real science … from unscientific superstitions by its reliance on observations, generalization, and repeated confirmation”, however it was crucial in forming the basis of this theory (400). Continental Drift was the precursor to plate tectonics in a sense as it used sensory observations including the examination of how continents appeared to fit together like puzzle pieces and how many plant and animal fossils as well as rock formations were shared among continents that currently have no physical connection. These observations led Alfred Wegner, the man who introduced continental drift, to make a general statement that all of the continents must have been together at one time and have progressively shifted because of some force (Ammon). Although this evidence was circumstantial and did not undeniably prove his theory, more proof was repeatedly found with additional fossils and rock formations that were discovered to be shared between continents. Conversely, flat earth theory uses a single experiment known as the Bedford Level Experiment which incorrectly stated the earth was flat (Cox). This experiment does use sensory observations and a generalization regarding said observations which is part of induction, but leaves out the necessary component of repetition that completes it. In

Have you ever wondered why the Earth looks the way it does today? Well, you are not the only one. Not too long ago was it that scientist asked themselves the same question and were able to come up with an answer. Now, lets take a quick look back at that question. Why do the continents look the way they do? Well, the short answer is basically plate tectonics. What is that you say? Plate tectonics is a theory that describes the formation, movements, and interactions of the Earth's lithosphere with its' asthenosphere. The lithospheric layer of Earth's crust is broken into plates that move on the asthenosphere, the layer located under. This theory is what basically explains how continents, volcanoes, and mountains got where they are today. Now,

1. Evidence that supports that continents have moved is the evidence of Pangaea. Some evidence from continents are matching rocks,fossils,glaciers,and structural relations, proving that at one point and time all the continents were all connected. With the discovery of tectonic plates and how they function help in the understanding of continents moving over time. As from what Pangaea was to how the continents look now and are currently moving apart but at a really slow rate.

Geoprocesses move our continents 2-3 cm a year. At a time in our world all our continents were connected. Geoprocesses modifies our surface such as plate tectonics, mountains, earthquakes and volcanoes. Mountains, volcanoes and mountain ranges are some of the best sites people see and all those sceneries are made by geoprocesses.

The outward flow of energy from the Earth’s interior drives plate tectonics since the fundamental properties of size, distance from the Sun, and rate of rotation are what drive the internal process, surface properties, as well as the atmospheric properties of a planet. Planet Earth is very large, has a hot molten lava core, and rotates faster than Venus or Mars and is therefore able to sustain volcanic and tectonic activity. Active volcanoes such as Mount Saint Helens are usually located in mountain ranges along the boundaries of tectonic plates because plate tectonics are what cause much of Earth’s geology including seafloor spreading and subduction which lead to earthquakes, mountains, valleys, and volcanoes. A subduction zone is

Having such dense vegetation, provides habitats to many living animals and microorganisms, it could cause overgrowth of plant and other species that could cause endemic diseases. Places like the desert, low biodiversity, has limited food sources to human and animal all together it could cause a low rate of rebirth for both animals and plants. Functional diversity has effected natural selection in great ways throughout history. One specifically being the process of tectonic plates which caused Pangea, continent consisting of all present-day continents, to split apart and turn into present-day continents that we now know and inhabit. The movement of these continents, made them experience climate change and specify which species would be well

Geologists trust that the world 's hull is isolated into huge plates that fit together like the bits of a mammoth jigsaw riddle. These plates are thought to move persistently, for the most part on a level plane. As per geologic hypothesis, the plates meet in no less than three ways, and two of these are imperative to our story: subduction zones (where one plate moves underneath the other), and change limits (where the two plates grind past each other). At some point around sixty million years prior, when our video starts, the lighter-weight North American Plate started abrogating or subducting the denser Farallon plate, and as it did, its external edge went about as a bulldozer, gathering up

The North Coast region, which includes RNSP and the adjacent offshore area, is the most seismically active region in the United States. As a result of frequent earthquakes, rapid uplift rates have led to landslides, actively braiding and shifting rivers, and rapid coastal erosion.

In the middle of the eighteenth century, James Hutton proposed a theory, uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg, 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham Ortelius in December 1596, who suggested that North, South America, Africa and Eurasia were once connected but had been torn apart by earthquakes and floods. He also discovered that the coasts of the eastern part of South America and the

“The good thing about science is that it’s true whether you believe in it or not,” stated Neil Degrasse Tyson. The ‘Theory of Plate Tectonics’ is accredited to most of the creations of mountain ranges, the Centennial Drifting Theory, earthquakes, and other landforms nature has made.
