What Are The Pros And Cons Of Fracking Essay

Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.

This type of eruption is driven by thermal contraction where the temperature difference between the two results in violent water-lava interactions. The eruption usually has bursts of tremors, geothermal activity, mushroom cloud formation, and a large amount of ash. These tremors can result in earthquakes and geothermal activity refers to the melting of the ice. When the volcano erupts, a mushroom cloud can be formed from 30 km wide and 15 km high. In addition, ash is formed by the magma and glacial ice.

Hydraulic fracturing, otherwise known as “fracking,” by definition, means the process of drilling and injecting fluid into the ground thousands of feet deep, at a high pressure; in order to fracture shale rocks to release the natural gases inside (Schrope n.d.). A more adequate explanation on to why we perform the method of “fracking” is that it is an easier process to obtain the natural gases inside the rocks. These natural gases are used for many sources of energy throughout the world. Natural gases have also been proven to be more cleaner and more efficient source than coal. The process of fracking involves drilling through deep wells into the shale rocks which breaks up the rock shales releasing these natural gases.

Volcanoes are openings in the surface of the earth from which gas or cold melton, or liquid, rock escape and cover the land with smoking hot lava. Also, gases and rock and shoot up through the opening and spill over or fill the air with lava fragments. Where are volcanoes found? Many active volcanoes are located/found around the edges of the volcanoes on the west coast of americas, the east coast of siberia, japan, the philippines, and in island chains from new guinea to new zealand this thing is called the Ring Of Fire. How volcanoes erupt.

Underneath the earth are plate tectonics, and when the earth drifts apart the plate tectonics move and cause many things to happen. Many of our landforms were created because of this. Three examples are volcanos, earthquakes, and mountains. To begin, volcanos are a great example of landforms being created by the movement of plate tectonics. When the plate tectonics move, it causes pressure inside the earth that creates volcanoes.

Introduction- Hydraulic fracturing or as we know it, fracking Is natural gas that trapped in tiny pockets in shale rock formation. Fracking involves injection of large amounts of water, sand and chemicals underground at high pressure to extract fuel. Environmental groups and some neighbors of oil and gas wells have linked fracking to water pollution and some have linked it to increased earthquake activity. Fracking is Regional and a old problem- When fracking started- Fracking began on June 1998 Pro- Some people think that it 's a good thing because we get natural gas that way. natural gas can be used a lot without affecting the environment.

The cause of this volcanic eruption is due to the subduction of the Manila plate, this is a destructive plate boundary. The subduction increases subterranean pressure which gets released through volcanoes, which in this case was Mt. Pinatubo. The eruption was violent and caused lahar, pyroclastic flow and a sulfuric ash cloud that reduced global temperatures by one degree Fahrenheit. (The 1991 Mount Pinatubo Volcanic Eruption)

While marble blocks are cut by gang saws and by vertile water is used as a coolant. The marble converted to powder, flows along with water as marble slurry. Water is reused till it gets thick enough to be insoluble for marble powder. Marble cutting industries are dumping in any nearby pit or vacant spaces. This leads to serious environmental

The plunger retracts against a spring when pressed against the concrete surface, and this spring is automatically released when fully tensioned, causing the hammer mass to impact against the concrete through the plunger. When the spring controlled mass rebounds, it takes with it a rider which slides along a graduated scale and is visible through a small window in the side of casing on which the observation gives the rebound number. Then the calibration chart is used to relate the rebound number to compressive strength of concrete. The typical calibration chart is shown in Fig. 8.3.

The mantle is the largest layer of the earth and consists of dense, heated rock [6]. The lithosphere is split into tectonic plates that slowly move due to the amount of heat from the earth's center causing molten rock to move in the mantle [7]. There are seven major plates and a large number of smaller ones on earth. The relative movement in which the tectonic plates meet, establishes the type of boundary (convergent, divergent, and transform) [8]. Along these boundaries are where earthquakes occur.
