The Molten Core Theory
The center of the Earth is composed of a solid metallic core 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 led 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 Earth’s core. This evidence includes information about the elemental make up of the Earth, the reason for the Earth’s magnetic field, and some of the possibilities of the Earth’s 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 known 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 properties we can begin to make judgments on the harder to observe questions, like that of the Earth’s interior make up. Knowing the properties allows for the determination of things on a much larger scale, such as the density of the Earth, which is crucial to understanding the Earth’s 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 Earth’s 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 it’s interior structure. Returning to ...

...it’s basic structure. Along with the new evidence of the Earth’s magnetic field originating in the Earth’s core, and new experiments, such as the multi-anvil press experiment, it is logical and more than plausible to believe that the Earth’s core is a liquid hot fluid made up of iron and nickel, surrounding a compressed solid metal center.

Treating the patient and family as one, can have improved outcomes, decrease hospital stays, increased patient satisfaction, and improved reimbursements for the hospital. Developing a relationship with not only the patient, but family as well, can pay off in the long run by providing better communication, better quality of care, and trust. The patient and family can be strong advocates for improved performance improvement efforts. Including family in the treatment of the patient treats the “whole” patient through their hospitalization. Involving the family can enhance the patients care.

“The objective of video games are to entertain people by surprising them with new experience” (Shigeru Miyamoto).Video games have been a leisure activity for many people around the world but for some people it has become a way of life. Video games help us escape everyday life and bring us to a land of imagination. That is why many people play video games because it is a great way to relieve stress. Video games have many benefits than just being fun. Not only are video games shown to have positive effects on the individual if used in the right manner, but it also helps to connect people with common interest; bring a sense of community. It is also a resourceful way to find a career path. The components
Gamification is something new in today’s society. However, it is becoming an enormous deal. From going to local places to an abandoned house. Turning everyday activities is presented very different between the two passages.
According to Medland (Medland, 2013), a great amount of time and money across the globe are spent on games, being one of the world’s largest forms of entertainment. Taking into account that games are played during our free time, at our own expenses and often requiring repetitive tasks, we still pose an unbelievable drive for gaming. The Gamification’s purpose is to make real life activities more engaging, by harnessing the psychological predisposition to engage in gaming using the same motivational mechanisms.
The basic science is pretty straightforward. The earth lurches from time to time because its outer shell is broken into huge, solid plates floating on a layer of molten rock that has the consistency of Silly Putty. These tectonic plates are constantly jostling each other, like rafts crowded into a...
Client centered care is what creates the foundation for the therapeutic nurse-client relationships. The Registered Nursing Association of Ontario (RNAO) recommends that nurses embrace the values of respect, human dignity, client as expert, and clients as leaders, to foster patient centered care (RNAO, 2002). A study done at Coventry University found that there were serious implications to care that was not family-center. Effective communication plays a large role in how the care is perceived by families and patients. It is extremely important for clients to receive constant and continual information from their healthcare professionals (Beckwitt, 2014). Relaying critical, sensitive information is difficult, but when t...
Time after time, science and technology have proven that we live on a spherical planet. Now that we have access to space, the easiest way to prove the Earth is a sphere is to leave it and view it
...ro level forum. She revealed the layers in the plot that tend to get overlooked when viewing a Hollywood musical. Also, her Freudian insight of Linda Low’s character, in which she explains the ego formation and narcissism, mirrors Marchetti’s view of the white knight. Hollywood narrations have notoriously reflected the white male, who I perceive as a representation of American national identity, as a highly narcissistic character. He is portrayed as the hero with patriarchal discourse and male privilege. Overall, both essays dive into the role these films took in constructing a national identity under the veil of a romantic narrative. Both speak to a political subplot on an unconscious, rather than diegetic level. In providing such an in depth analysis, they uncloak the racial and national assimilation that these films depict in relation to the East and West.
Mercury’s large inner core and how the planet was formed is a subject of debate, with two main theories. One theory suggests that the sun vaporized all of the elements that would have built a crust on mercury leaving only the core. The second theory, the large impact hypothesis claims that the chaotic movement of the early solar system resulted in a massive collision with Mercury, this collision caused the lower density material to be cast off of the planet leaving only the massive iron core. In time sediment settled on Mercury leaving a thin crust on the planet.
Earth was formed 4.8 billion years ago (3) . It became the home for hazelnuts because it had an atmosphere and environment which allowed for life to prosper in later years. Earth’s surface was once composed of a single landmass, known as Pangaea (1).Over time it was broken up into seven different plates which were free to move as a result of movements in the hot, semi-liquid magma beneath the...
The lithosphere is an open system, which contains all of the cold, hard, solid rock of the planet's crust (surface), the hot semi-solid rock that lies underneath the crust, the hot liquid rock near the center of the planet, and the solid iron core (center) of the planet (Answers.com). On Earth, the lithosphere comprises the crust and the upper part of the mantle. The lithosphere is about sixty miles thick (Lenkeit).
Gravity is the force that pulls two objects together, and the mass of the human body depends on gravity. The more the mass there is, the amount of the gravitational force will increase. The study of the Earth’s gravitational field itself is complex and deeply fascinating. Likewise, studying its relation to the human body makes it even more thought provoking. A gravitational field is simply the area of space neighboring a body that has another body experiencing a gravitational attraction force. As human beings and just general species, our state in Earth is not the same as it is up in the atmosphere or another planet. Unfortunately, the term “gravity” is thrown around futilely these days, but in this essay you will learn its purpose in our Earth, and all the notions that go along with it.
