Earth Stores Heat From the Rest of The Establishment

Since formed 4.5 billion years ago, Earth's temperature continues to cool. However, recent research has shown that the earth still keep the heat emanating from the initial formation.

For seven years, particle physicist from Tohoku University, Itaru Shimizu, examining the earth's internal heat using equipment that is embedded in the belly of Mount Ikenoyama. The detector is able to see neutrinos, invisible and unique particle capable of penetrating solid objects. Lapse of 2002 to 2009, Shimizu and his team discovered 841 neutrinos. A total of 485 of these neutrinos produced by nuclear reactors, and 245 were from outer space. While the neutrino rest 111 are thought to originate from radioactivity within the Earth. "A more rigorous segregation reduced the number of neutrinos from the earth to 106 particles," Shimizu said in a paper in the journal Nature Geoscience, July 18, 2011. Although the number of neutrinos that netted very little, researchers estimated that more neutrinos yahg escaped capture. Radioactivity of uranium-238 and thorium-232 is estimated to produce 4.3 million neutrinos per square centimeter of the earth's surface every second. The amount of radioactivity generated energy estimated at 20 trillion watts. The process of potassium-40 radioactivity measured by separate detectors generate 4 trillion watts of energy. "Energy is a combined 24 trillion watts of radioactivity accounted for 54 percent of the total generated heat of the earth," he said. So, what about the remaining 46 percent of other geothermal? According to Shimizu, some geothermal comes from the rest of Earth's formation 4.5 billion years ago. Heat is constantly flowing from the bowels of the earth to the surface. According to planetary physicist at the California Institute of Technology, David Stevenson, the findings of the deposit the residual heat of the earth formation is important in geological knowledge. "For the first time researchers can measure the residual heat of the earth when the newly formed planet," says Stevenson.*** [SCIENCEMAG | ANTON WILLIAM | KORAN TEMPO 3595]
