The Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere, or, as more colloquially known, the five layers of the Earth. Although each layer is important, each living thing resides on the Lithosphere, which happens to rest on the Asthenosphere, the upper part of the Mantle. Forces caused by these two layers both contribute to the theory of Plate Tectonics, which happens to be interconnected to Earthquakes and Volcanoes. Without Plate Tectonics, the other two occurrences simply cannot exist, Of course, to comprehend how Earthquakes and Volcanoes work, Plate Tectonics must be understood first. So, to digress, it is the theories of Seafloor Spreading, proposed by Harry Hess, and Continental Drift, conceived by Alfred Wegener united under…
INTRODUCTION The science of magneto hydrodynamics (MHD) deals with geophysical, astrophysical and engineering problems since many years. This subject has attracted attention of many researchers in the MHD flow on Newtonian fluids on plate, cones and disks. Hari R [30] investigated the chemical and radiation effects on MHD casson fluid flow past an oscillating vertical plate embedded in porous medium. Subbaiah Naidu [70] studied the effect of Hall current on free convective flow of stratified…
Sciencia is a world analogous to Eath. Based on the present day plate boundaries and similarities on multiple continents, It’s believed that the continents of Sciencia were once together as a supercontinent called Edisonia. The supercontinent held 6 of the 8 modern continents, which broke apart due to tectonic forces in the Lithosphere. Also, the 7th and 8th continents were believed to have formed from volcanic eruptions on convergent plate boundaries. The edges on the modern- day Sciencian…
Volcanoes are generally found in three locations: constructive and destructive plate boundaries, as well as hotspots. The most explosive and potentially the most hazardous volcanoes are found on destructive, convergent plate boundaries. Here, one plate subducts beneath the other generating intense heat and pressure, melting the rock and sediment to form an acidic magma chamber. This viscous magma is resistant to flow and therefore results in violent, dangerous eruptions involving pyroclastic…
Tambora is plate tectonics. Islands in this chain along Indonesia are located along the convergent plate boundary of the Eurasian and Australian plates. A convergent boundary is the place where two tectonic plates collide. This can be oceanic-oceanic, oceanic-continental, or continental-continental. In the case of Mount Tambora, the Australian plate slides below the Eurasian plate. In this case a subduction zone is created. Here the sliding of the Australian plate under the Eurasian plate…
An earthquake is the phenomenon that a huge energy suddenly released and appeared in the Earth’s crust when two moved plates slip past one another. The earthquakes usually happen in the convergent boundaries, divergent boundaries and transform boundaries. In the three kinds of boundaries, the convergent boundary often produces the largest magnitude earthquakes. Because when the two plates collide strongly in the convergent boundary, the extreme pressure and the great friction will appear. So the…
Japan is associated with so many natural disasters. This is because the island, Japan is located where the North American, Pacific, Eurasian, and Philippine plate meet, also known as plate boundaries. Japan is also located where the Pacific plate and the Philippine plate are subducting. This results in the stress building up where the two plates are subducting. How do plates move? Well, plates move when uneven heating in the mantle creates currents. This current is a convection current, and…
intermediate, or deep? Fourth, explain the type of plate boundary the earthquake from the third question was near and why are earthquakes common to this area? Fifth where was the deepest and the…
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 in which was proposed about a hundred years ago. This theory states that our Earths lithosphere is divided up into several different plates. Scientists have found that during the past millions of years, these plates move and have caused many phenomenon’s. There are three types of plate boundaries identified today: divergent, convergent, and transform. One of the most acknowledged discoveries made was the Isthmus of Panama. An isthmus is simply a thin strip of…
