The Molten Core Theory Essay -- Geology Education Earth Essays

The Molten Core Theory The center of the Earth is composed of a solid metallic burden out surrounded by a molten layer of liquid metal. This paper will discuss the reasons to believe the theory that the Earth has a molten core, and the important discoveries that have lead to this generally accepted theory. It is very reasonable to agree with this theory when paying credence to the logical evidence that answers questions about the Earths core. This evidence includes selective information about the elemental make up of the Earth, the reason for the Earths magnetic field, and some of the possibilities of the Earths formation.Dr. Ken Rubin, an assistant professor of geology at the University of Hawaii. Explains that the Earth is made up of an accumulation of all of the sockn elements combined in different forms to make the various rocks, and minerals that are present in the crust, mantle, and core of the Earth. With the understanding of these elements and their propertie s we can begin to make judgments on the harder to observe questions, like that of the Earths interior make up. Knowing the properties allows for the determination of things on a much larger scale, such as the tautness of the Earth, which is crucial to understanding the Earths core. Much of what is known about the Earth can be learned from observing the other planets in our solar system. Every planet has a different mass and density. That means that planets create varied gravitational pulls on each other. By testing the effects of the Earths orbit on that of the other planets it becomes possible to estimate an overall density for the planet. Knowing the density of the Earth is extremely important to understanding its interior structure. Returning to ... ...its basic structure. Along with the new evidence of the Earths magnetic field originating in the Earths core, and new experiments, such as the multi-anvil press experiment, it is logical and more than plausible to believe that the Earths core is a liquid hot fluid made up of iron and nickel, surrounding a compressed solid metal center.
