Volcanoes Research Paper

Superior Essays
The Earth is a birthplace for incredible natural disasters. These are earthquakes, tsunamis, and tornadoes to name just a few. But one disaster, famously known for its ability to spew hot magma from an opening in its surface is considered the most captivating. Volcanoes, whose name originates from Vulcan the Roman god of fire, are some of the most stunning and fascinating processes to occur underneath and on the surface of the earth. To better understand volcanoes this essay will touch on several topics including, what volcanoes are, their various types, their relationship with earthquakes, hazards and examples of volcanoes. From the typical ‘red foam’ erupting volcano science project to the real deal natural disaster, almost everyone has a …show more content…
Though one familiar image may come to mind, there are actually many different types of volcanoes. Cinder cone volcanoes are the most common type. According to an article by NASA, “these volcanoes consist almost entirely of loose, grainy cinders consisting typically of basaltic and andesitic material and almost no lava” (Volcano Types). Cinder cones are small volcanoes and tend to only rise about 1,000 feet and their craters are small and have steep sides. Though usually classified as a major volcano, they are much smaller than most other major volcanoes and can sometimes even form along the sides of shield and composite volcanoes. Composite volcanoes, also known as stratovolcanoes, are “symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks and bombs and may rise as much as 8,000 feet above their bases.” (Volcanoes General FAQ’s). They are very steep and can be 10-20 miles wide. Composite volcanoes have many vents which pyroclastic flows escape from. These volcanoes usually have explosive eruptions due to their thick, highly viscous lava that moves at high speeds, this makes them very dangerous. Composite volcanoes are also conspicuous and “disguised” as mountains. Another type of volcano is the shield volcano. They are very large, and can be …show more content…
Earthquakes may be caused by the movements of magma within a volcano’s chamber, but also vice versa with heavy seismic shifts cracking open into the inside of a nearby volcano. Both volcanoes and earthquakes can associated with tectonic plate movements as well. According to the National Oceanic and Atmospheric Association, “the Ring of Fire is a string of underwater volcanoes and earthquake sites around the edges of the Pacific Ocean.” Most of the Earth 's volcanoes and earthquakes occur around the Pacific Ring of Fire because that is the location of most of the Earth 's subduction zones. Subduction is when a tectonic plate sinks beneath another, and a subduction zone is the area in which subduction occurs. In this case, dense oceanic plates sink beneath the less dense continental plates. But what causes volcanoes and earthquakes to happen along these

    This volcano has many special characteristics and is famously known across the globe. Stromboli is known to be a stratovolcano. According to the Department of Geosciences at Oregon State, stratovolcanoes tend to be made up of two components, one being pyroclastic material and one being lava. Imperial College of London defines these types of volcanoes as steep-sided volcanic edifices consisting of pyroclastic material and lava flow that dip away from central vents and mostly consist of characteristic of intermediate magmas. Therefore, because Stromboli is such a powerful volcano, many may believe that it is highly dangerous.…

    Volcanoes Volcanoes are magnificent yet dangerous structures created by the forces of nature when Earth’s tectonic plates diverge and collide against each other letting the Earth vent out pent up gases, magma, rock, and ash. There are three types of volcanoes called Shield, Stratovolcanoes, and Cinder cones. Volcanoes are further labeled as active, dormant, or extinct depending on recent activity. The magma underneath the Earth’s mantle is responsible for the explosion and creation of volcanoes around the world. About 90 percent of all volcanoes on Earth are found in the Ring of Fire located in the Pacific Ocean.…

    “Volcanic eruptions are the most awesome and powerful display of nature’s force” (Sigurdsson et al. 2) is a quote from the author Haraldur Sigurdsson that describes the breathtaking sight one may behold from the experience of witnessing the eruption of a volcano. However, innumerable aspects contribute to this gorgeous display. The fascinating eruption varies vastly depending upon numerous factors working within a volcano, and the shapes of volcanoes may affect the way an environment copes with an eruption and may cause volcanic lava and debris to travel in differing paths. Location also plays an important role in the sight and composition of volcanoes, because different regions contain various types of volcanoes.…

    Sun and moon cause tremors by creating tides in Earth 's crust (Live Science Staff). When plates squeeze or stretch, huge rocks shift making faults and causing earthquakes ("Earthquakes"). Faults are where rocks slide past each other and cause a crack ("Earthquakes"). Faults have been the result…

    The eruption of Mt. St. Helens could be seen for hundreds of miles. The increase of pressure or heat causes the eruption. An earthquake can cause a volcano with its additional disruption and pressure. Magma is melted, liquid rock so of course, it is harmful to anything in its path.…

    The amount of silica present in the magma determines its viscosity with high silica content causing a high viscosity and a low silica content produces magma with low viscosity. Volcanoes are found throughout both the North and South Islands of New Zealand although the majority are located in the North. There is a mixture of both active and dormant volcanoes. All of the volcanoes found in the South Island were once active but are now dormant. This is due to the plates moving and the magma no longer being able to reach the volcano.…

    3. Surface waves: Primary and secondary waves affect the surface resulting in the generation of waves called surface waves. These waves are considered to be the most destructive waves. Volcanoes Plate movement can also cause another natural disaster called volcano. Under certain conditions, when plates are pushed or pulled together, volcanoes are created thus, both earthquakes and volcanoes tend to occur in the same place.…

    Mount St. Helens is located in southwestern Washington in Skamania County. It is 96 miles south of Seattle, Washington, and 50 miles northeast of Portland, Oregon. It is also known as Louwala-Clough, or Lawetlat 'la to the indigenous Cowlitz people, and Loowit to the Klickitat. Mount St. Helens is an active stratovolcano or composite volcano, a steepsided and often symmetrical cone constructe. Thess type of volcanoes tend to erupt explosively and pose considerable danger to nearby life and property of lava flows, ash, and other volcanic debris.…

    An earthquake happens because of a sudden release of energy in the Earth’s crust that creates seismic waves. A tectonic earthquake begins by an initial split at a point on the fault surface, a process known as nucleation. The rupture begins to spread along the fault surface. It manifests itself by trembling and sometimes, displacing the ground. Earthquakes are mostly caused mostly by rupture of geological faults, but sometimes, also by volcanic activity, landslides, mine blasts, and nuclear…
