Loud booms rang out. The quivering began to intensify, causing belongings to fall in residents’ homes. It was the beginning of the 5.7-magnitude Oklahoma earthquake, which struck on November 6, 2011 and resulted in significant structural damage (“Oklahoma’s Largest Quake in Decades Buckles Highway; Rattles Residents,” CNN). A journalistic study—published in the journal Geology—conducted in 2013 showed that the 2011 earthquake was actually caused by fracking, a practice in which water is injected into the Earth’s ground (“Wastewater Injection
Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21). These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
Convection Currents The Alaskan Way Viaduct will collapse if an earthquake happens. Tectonic plates rubbing together causes an earthquake. What causes them to rub together? An earthquake happens through a sequence of cause and effect. Altogether, temperature, density, and convection currents work together to cause an earthquake.
The hospitals and clinics reported that over 1,000 documented cases of water contamination surround the areas of gas drilling involving sensory, respiratory, and neurological damage due to ingested contaminated water. The amount of water used in these processes and the amount of waste produced are also major issues. To start the oil fracking process, a massive amount of water is used. This means, a huge amount of water being transported to the fracking site, at significant environmental cost. It takes 1 to 8 million gallons of water to complete each fracturing job.
Analysis The Beginning In 1949, fracking was introduced to oil companies as a way to use hydraulic fracturing by creating vertical wells. Fracking is the use of pumping water, proppant, and chemicals down a well that is either gas or oil in order to break channels into rocks that contain these oils or gas. In order to properly obtain these pressure oils, we have to create holes in the thousands of miles of rocks below
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes. How do earthquakes form?
Fracking: The New Energy Rush “Fracking is taking place from sea to shining sea” was a quote used within the documentary that stuck out to me. Prior to this documentary, I had no previous knowledge on the subject; the video made me anxious to learn. Fracking is when a crane goes down approximately two miles underground, which leads to it turning horizontally. After the crane goes horizontally, water, sand, and chemicals are released. This causes breaks and cracks throughout the rocks, causing shale gas to occur.
The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. Examples of these rock types include marble, slate, gneiss, schist.Metamorphic rocks can be formed from any other type of rock - sedimentary or igneous. Remember these two examples of common metamorphic rocks and where they come from: slate is formed from shale.main ways. Clastic material (pieces of other rocks or fragments of skeletons) may become cemented together and chemical precipitation and evaporation can form sedimentary
Why is fracking dangerous? During the fracking process natural gases are realized into the well where they are drilling often contaminating the nearby groundwater with methane gases and chemical toxins. After the fracking process the waste fluid is evaporated releasing volatile organic compounds causes acid rain, contaminated air, and ozone at
The central cores of major mountain ranges consist of intrusive igneous rocks, usually granite. When exposed by erosion, these cores (called batholiths) may occupy huge areas of the Earth's surface. Coarse grained intrusive igneous rocks which form at depth within the crust are termed as abyssal; intrusive igneous rocks which form near the surface are termed hypabyssal. Extrusive igneous rocks Extrusive igneous rocks are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. Extrusive Igneous rocks cool and solidify quicker than intrusive igneous rocks.
Fracking has actually been taking place since the 1940’s, but not until it was combined with horizontal drilling was it extremely useful (“Hydraulics” 71-75). In the past fifteen years the fracking business has skyrocketed. By 2015 thirty-five thousand wells are using fracking methods in order to extract the natural gases each year. Ninety percent of all gas production in the United States would be impossible without fracking (“Hydraulics” 71-75). More than ninety percent of natural gas wells in the U.S. rely on fracking (Howarth, Ingraffea, and Engelder).
Ali Elkanuni 040809006 November 24, 2015 Here Comes the Sun Analysis Introduction: Hydraulic Fracturing, also known as fracking, is the process in which companies use in order to extract natural gasses. High-pressure fluid is injected into rocks deep underground so that it fractures shale rocks to release natural gas inside. This natural gas is used for energy, gas and oil. There has been a controversy about fracking since it was introduced about 60 years ago. Although it was a great technological advancement, it has raised both health and environmental concerns in the areas fracking is occurring.
