Geothermal Energy Essay

When the water or lava comes up from the inner core from either a volcano or from a geyser, the temperature of the liquid it produces would be able to produce the same result we get from using fossil fuel to supply our energy. Geothermal energy could possibly be used to directly heat buildings or used to power turbines and thus generate electricity.

The difference between volcanoes formed through hot spots compared to those formed by submerging tectonic plates is that the magma released in volcanoes from hot spots has different characteristics than other volcanoes. For instance, the magma is released due to its ability to continually break through the lithosphere, rather than being pressured by the sliding of the tectonic plates. Both types of volcanoes are similar because of the fact that they both are temporary features on the planet due to the constant motion of the plates and the cooling of the lithosphere beneath the tectonic

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

As scientists are looking for a solution for our energy shortage issue that they predict we will face in the near future, the author of the passage argues about the future use of geothermal energy as an alternative energy source that can provide us with a resonable solution. The author cites several claims in his or her passage to support his position and convince the reader of his point of view. I think that most of the pieces of evidence that the author provided are valid and credentials to his or her main argument.

Geothermal Energy: it means the use of heated water and stream to power the power station for turning steam and heated water to electricity but it's expensive

The tectonic plates are all over the earth’s surface. Over the years, these plates and their characteristics have become common knowledge. These plates move around 3cm at least every year and they move in different directions due to the convection currents of molten magma that flows beneath them. [Raunekk 2010] A convention current definition is “a current in that a fluid is that a results from convection.” [Earth’s dynamic] Then the movement of these plates are the main forces behind catastrophic events such as earthquakes, volcanic eruptions as well as the development of mountains. In addition, this means that these plates are the main reason why our planet surface looks the way it does today. When processes such as pushing, folding and tilting (as well as other forms of tectonic movement) take place, it shapes our planet [Weather Wizkids 2015] as well as playing its part in heating it to an unbearable degree along with the aids of ocean currents. In comparison to the plates that mainly produce heat through its products the ocean current move the heat all over the earth’s surface.

Volcanoes are wondrous formations on the earth. Humans are fascinated by them but are often very cautious about volcanoes. They see them as explosive, lava spewing mountains often causing natural disasters. These are just some of the effects of a volcano but plus side to it is that its energy can be harnessed. Energy that can be used from a volcano is Geothermal Energy. It is a clean, renewable energy which uses the steam produced from vents and hot springs near volcanoes. In this paper I am going to prove why Geothermal Energy is good for the environment and the society. Firstly I am going to discuss what geothermal energy is. Secondly, I will discuss the benefits of geothermal energy to the environment. Thirdly I am going to show how geothermal energy is beneficial to the society around its source. Lastly I will compare geothermal energy to other energy sources and show why geothermal energy is the way to go.

A hot spot is fed by a region deep within the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock at the base of the lithosphere, where the brittle, upper portion of the mantle meets the Earth’s crust. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes.

Earthquakes then trace the trail of the downward-moving plate because it descends into layer, a trench forms, and because the subducted plate part melts, rock rises to make continental volcanoes.

At convergent boundaries, mountains, volcanoes, and other natural things can occur because when the plates collide, one plate is forced above the other and this happens because of the density and composition of the minerals and elements in the plates.

It's clean and sustainable. In order to find geothermal energy, it is available near geological hot spots. These hot spots are an area in the mantle from which heat rises as a thermal plume from deep in the Earth. Under these spots, a molten material called magma is underneath the crust of the Earth and penetrates it. Magma can cause and therefore turn into steam or hot water. People collect this steam or water by putting steel pipes in the hotspot and then connect the pipe to a power plant on the surface. So, the power plant uses the steam or water into using it to make a steam turbine move (“Geothermal Energy Basics” 2017). The steam or water turns into a vapor and then pushes the steam turbine in order to collect the warm energy. Some pros to using geothermal energy is that since its source is the almost unlimited amount of heat generated by the Earth's core, it will never run out. Another pro is that it can create jobs because someone is going to have to work in the power plants. And that using geothermal energy is very efficient (300- 500% compared to 90% of the best furnaces) (Michaelides 2017). But, there are also cons. One con is that in order to get the steel pipes to suck up the heat, it uses energy in the process. Also, in a bad scenario, geothermal power plants can cause earthquakes. In order for countries to use geothermal energy, they must have money to build several power plants, and must utilize any hot

In this mantle, there are convection currents. Heat from the core causes convection currents to slowly move the Earth 's crust around. All over the crust’s surface, crust is destroyed, and reformed. All plate boundaries movements are moved by convection currents in the mantle. At the boundaries between plates, magma is able to force its way to the surface and escape as lava. There are three different types of plate boundaries known as convergent, divergent, and transform.

Nuclear power and coal are two of the main sources of electricity used in the United States today. Coal and Nuclear power along with Natural Gas make up over 93% of the power we use. Yet they are also the most feared and misunderstood. While both have negative connotations, they both are clearly still doing the job better than other alternative energy.

What would happen to our world if our energy unexpectedly disappeared? Fossil fuels are very important to our world because they provide an overwhelming majority of our world energy. So, what happens when they run out? This research paper confronts this question with a balanced view attempting to address the issue of what sources might provide energy in the future and come to an objective conclusion. As the world enters a new century, new sources of energy such as wind, solar, and hydrogen power need to be developed to help the world keep running on all cylinders. With the development of these new energy sources, our world would become a cleaner place and the energy crisis would straighten itself out.

Ridges occur at the boundaries between the tectonic plates of the Earth’s crust, and the spreading centers of the sea floor (Van Dover 2000). It is at this location that hydrothermal vents are formed. When plates are pulled apart by tectonic forces, seawater seeps through the openings in the earth’s crust (NOAA, Van Dover). The freezing seawater is heated by hot magma that is rising to fill the gap left behind by the separated plates (NOAA, Van Dover). The seawater does not reemerge through the magma strictly as seawater, but rather as a solution created from chemical reactions that remove oxygen, magnesium, and sulfates from the water, and also leach metals from the surrounding crust (WHOI). As it pours from the magma the heated liquid meets cold seawater, creating another collection of chemical reactions (van Dover, WHOI). In this set of reactions, sulfur and other minerals precipitate to create metal-rich deposits and towering vents.
