The Earth’s Nuclear Core Essay

Credibility: The world's first exposure to nuclear energy came with the detonation of two atomic bombs in Japan in 1945. Scientists perceived a positive aspect of

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

•     Waste from nuclear energy stays radioactive for thousands of years. Great care has to be taken in storing this waste safely.

Presently, nuclear fusion and nuclear fission are being studied, and even used in some countries as a power generator. The enormous energy produced by nuclear fission and fusion could light up a big city for a hundred years or more and we do not have to worry about it polluting our environment because nuclear energy is a green energy. Moreover, in a long term, the cost to generate power using nuclear is far less than the cost of generating power using fossil fuel.

The Earth is dying and things are going to go haywire up until its final moments, unless the United States Government fixes the planet -- at least, that is the premise of The Core (2003). There are many scientific inaccuracies throughout this movie. I was honestly astonished by how little the writers reviewed their science, because it is what we can definitely label as “bad.” In fact, the movie has even earned a very unhappy title from quora.com, being labeled “The Most Inaccurate Movie, In Terms of Science.” Let’s now delve into the juicy hunk of bad science that is The Core.

The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900’s. John D. Cockcroft and Ernest Walton confirmed this by experiments in 1932. Then in 1938, nuclear fission was discovered by German scientists, and it was feared by many of the U.S. scientists, that Hitler would try to build a

It was first developed in the 1940s, and during the Second World War to 1945 research initially focussed on producing bombs which released great energy from the atoms of particular isotopes of either uranium or plutonium.

Even though it seems very possible, the core stopping in unlikely without a probable cause other than the so called “ Project Destiny “. (http://www2.lbl.gov/Science-Articles/Archive/Phys-earth-core.html ) This would not work because the impact we need to widely reach the entire surface of the Earth in order for it to work, not to mention the countless riple effects that it would need to go through to impacted, such as; earthquakes, seismic waves, and so on.

It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core and mantle formation, as well as the eventual production of the continental crust.

The “Bad” Science in The Core The movie, The Core, has a lot of “bad science” in it. First of all, the movie is about the start of the end of the world when the core stopped spinning. If the spinning of the inner core would stop, then the spinning of the iron core in the center of the Earth would stop too.

the Earth at tremendous velocities causing them to join the molten and create a crust

Bad science is when a person or group of people test something out, not knowing what could happen, and not doing any research beforehand. There is a bunch of bad science examples in the movie “ The Core.” Such as when they went into the mantle and tried to like jump start the flow of the mantle and tried to my the core spin again. I do not think you can just enter the earth's mantle and not expect to burn up with in milliseconds. In the movie the core would not just cease and refuse to rotate. http://geolor.com/The_Core_Movie-Facts_and_Fiction.htm . it is not possible at all for a few people to control such a huge mass of molten liquid. In the movie, they literally just go right into the mantle and start their process. How would there possibly

The world as we know today is dependent on energy. The options we have currently enable us to produce energy economically but at a cost to the environment. As fossil fuel source will be diminishing over time, other alternatives will be needed. An alternative that is presently utilized is nuclear energy. Nuclear energy is currently the most efficacious energy source. Every time the word ‘nuclear’ is mentioned, the first thought that people have is the devastating effects of nuclear energy. Granting it does come with its drawbacks; this form of energy emits far less pollution than conventional power plants. Even though certain disadvantages of nuclear energy are devastating, the advantages contain even greater rewards.

Nuclear energy has been around longer than people think. In 1934 Physicist Enrico Fermi experiments in Rome showing that Neutrons can split many kind s of atoms. In 1946 the Atomic Energy Commission was created to explore peaceful uses of energy and nuclear energy development. In 1951 an experimental Breeder reactor produced the first electric power from nuclear energy in

Getting energy from nuclear reactions is a well-established science, tracing back to the discovery of radioactive elements, and eventually to harnessing the energy within those reactions for human needs. The basis of nuclear power is the use of nuclear fission to generate heat, which changes water into steam, and powers a turbine. Nuclear fission is related to radioactive decay, which was discovered in the late 1800s by Henri Becquerel and furthered by Marie and Pierre Curie. Nuclear fission itself was the work of Enrico Fermi – a physicist from Italy. Fermi would later help create the first self-sustaining chain reaction on the grounds of the University of Chicago in 1942. The understanding of nuclear fission and the ability to create chain reactions would lead to the Manhattan Project, culminating in the dropping of two nuclear bombs over Japan at the end of World War II. The technology would later be adapted into more peaceful purposes such as generating energy. Nuclear fission works by bombarding the radioactive element – usually uranium, but sometimes plutonium – with neutrons. When the neutron hits the element, it will split into two lighter atoms, releasing more neutrons, and energy. Those
