For centuries, mankind has wondered how the moon came to exist. The Greeks, the Romans, and the Egyptians all conjured their own myths and theories as to how the it came to be. Few people continue to believe these today, though, as new, scientifically backed theories have formed. Scientists believe that the moon’s formation either followed the co-accretion model, the capture model, the fission model, or the big impact model. The co-accretion model suggests that the Earth and its moon formed simultaneously from the same debris. This theory does not support the Earth and the moon’s difference in iron contents, so most scientists do not believe this occurred. The capture model proposes that the moon formed somewhere else in the Solar System and was later pulled by gravity into orbit. This theory also possesses problems as the physics of capturing an object as large as the moon is …show more content…
This theory would suggest that the rock densities of the earth and the moon would be the same, but this is not the case. The most accepted and scientifically supported theory is the big impact model. A vast majority of scientists believe that approximately 4.5 billion years ago, in the Hadean Eon, a large protoplanet struck Earth. This object, cleverly named “Theia” after the Greek goddess who gave birth to the goddess of the Moon, was roughly the size of Mars and the majority of the material that hit Earth merged with the planet in less than 24 hours. A disk made up of debris, gas, and molten rock formed along the Earth’s equator. This collection of materials from Theia and the Earth coalesced over time and half of the material formed the moon, while the rest fell to Earth. This theory came about in the mid-1970s, and it has provided reasoning for a lot of the problems that the other models face. The theory accounts for the lack of a substantial iron core in the Moon.

Final Team Paper

...Final Learning Team Paper GLG/150 Final Learning Team Paper During the early days of mankind, humans were led to believe that he or she were the sole entity of the universe. The Earth was thought of as exact center of the solar system, and that other planets revolved around it. Through the efforts and determination of individuals who refused to believe unchecked facts or documents, Earth is not the center of the universe but is instead a small piece to a larger solar system. The discoveries made by earlier pioneers of science Copernicus, Kepler, Galileo, and Newton. Developed ideas that help individuals understand the concepts of motion, and the formation of celestial bodies in space. Theories of gravity and space dramatically changed the views in which Individuals determine the origins of our Moon and other planets within our Solar System. As science and technologies progress, ideas of formations and motions in space provides more educated theories of how our world, or universe has formed and will continue to function. The Earth was formed about five billion years ago and is the earliest material in the solar system, which a solar nebula that collapsed from the formation of the sun ("How Did the Earth Form", 2012).

...Evolution Through the Solar System Abstract Over the course the class has been about many different things through our solar system, land features, and more. This week we had to put together a paper describing how evolution has taken place through our solar system. The main objectives of the paper are to include the formation of the planets, the motion of the planets, the early revolution. Also, discussed is the scientists who discovered these properties of our solar system. For example Copernicus, Newton, Galileo, and Kepler. These scientists have all created or in some way helped to discover something new about our solar system. Evolution Through the Solar System Though scientists have been studying the solar systems for years. There are still discoveries made each year. Many of the discoveries have been interesting from the formation and motion of the planets, the early revolution of the planets, and the scientists who discovered what we know today. Formation Scientists have been studying the origin of our solar system for hundreds of years. Some findings are well supported while others are not as well received. The best news is we are not done concluding the formation of our solar system just yet. In 2006, the distant ice-covered body known as Pluto was reclassified as a dwarf and changed the model of our solar system from nine planets to eight. Today a planet is defined as, “A full-fledged planet is an object that orbits the sun and is large enough to have...

Author’s note I chose this topic on the basis it was the most difficult topic to research. I am fascinated with the celestial bodies that encompass our solar system. The Moon, being such an influential entity on our planet, has also one of the most mysterious findings our scientists have discovered. The Artificial Moon Justin Jones EN1320 Andrew A Bowen Abstract This paper analyzes several works on the Moon and its characteristics and geological features. The Moon is the largest satellite of a planet in the Solar System relative to the size of its primary, having 27% the diameter and 60% the density of the Earth, resulting in 1/81 its mass. The Moon is a paradoxical celestial body, raising questions about its composition and origin. Isaac Asimov wrote, there is no astronomical reason why the moon and the sun should fit so well. It is the sheerest of coincidences, and only the Earth among all the planets is ‘blessed’ in this fashion” (Samone 2012). Nobel chemist Dr. Harold Urey suggested the moon’s reduced density is because of large areas inside the moon where is “simply a cavity” (Regehr 1995). Carl Sagan also writes, “A natural satellite cannot be a hollow...

Developing Diverse Team

...Development, Texas A&M University, College Station, Texas, USA Abstract Purpose – The use of teams in organizations given the current trend toward globalization, population changes, and an aging workforce, especially in high-income countries, makes the issue of diverse team building critical. The purpose of this paper is to explore the issue of team diversity and team performance through the examination of theory and empirical research. Specifically, the paper seeks to answer the question: “How might individuals with diverse characteristics such as culture, age, work experience, educational background, aptitude and values, become successful team members?”. Design/methodology/approach – A review of theories that are pertinent to individual differences and team formation, including social identity theory, mental models, inter contact theory, social comparison theory, and chaos theory, was conducted. Team formation and diversity literature were reviewed to identify ways of developing diverse and effective teams. Findings – It is a truism that working together in teams is a smart way of achieving organizational performance goals. This paper discusses the theories, research and practices that underlie the development of efficient and effective teams. It demonstrates that recognizing the underlying individual differences, mental models, and assumptions that team members bring to the organization can help build teams that...

The empirical results indicate that there exist two threshold values of 32.88% and 55.89%. The latter is lower than the Maastricht criterion and Stability and Growth Pact of a total external Debt per GDP ratio at 60% in the OECD countries. Both thresholds divide our panel into three regimes. In the middle (stimulus) regime, the Debt per GDP ratio has a positive impact on real GDP per capita, which is consistent with the stimulus view (Eisner, 1984). However, the impact becomes negative and consistent with the crowding-out view (Friedman, 1977, 1985) in the left and right (crowding-out) regimes. Based on our findings, we find no supportive evidence for Ricardian view (Barro, 1989). Therefore, our empirical results have important implications for fiscal policymakers in these Latin...

The Endosymbiotic Theory: Cellular Theory

...Biology Semester 1 Research Project Cellular Process Meagan Baggett 4th Period The endosymbiotic theory explains how eukaryotic cells may have evolved from prokaryotic cells. Symbiosis is a close relationship between two different organisms. The discovery of the endosymbiotic theory took hundreds of years to be considered as real and was eventually it was finalized. The endosymbiotic theory is believed to be first introduced and described by Andreas Schimper in 1883. Schimper was a German botanist and phytogeographer. He was born on May 12, 1856 and he passed away on September 9, 1901, at the age of forty-five.

Enceladus Research Paper

...Enceladus Research Paper Enceladus, the sixth largest of more than 62 moons that orbit Saturn, however of the 62 Enceladus is one of the most prominent and most varied moons to cycle the planet. Unlike most moons Enceladus is a very bright body, reflecting almost 100 percent of the light that that strikes its surface (making it one of the brightest objects in the solar system). With that being said, it still cannot be seen with the naked eye and must be viewed from a rather large telescope. This is due to the fact that it is small in comparison to the planet itself and that it can easily be outshined by the rings it resides in. Enceladus was first observed by William Herschel on August 28, 1789 when turned his 1.2 meter telescope to the ringed planet Saturn. Herschel managed to avoid a large amount of the glare from the rings and get a much clearer view of Enceladus by observing it during Saturn’s equinox (Redd, 2013. "Enceladus: Saturns Tiny, Shiny Moon "). Herschel initially named the moon “Saturn II” which stuck with it until 1847 when William Herschel’s son, John Herschel, published a report which suggested that the moons be named after the various titans from Greek mythology (seeing as they were orbiting Saturn or Cronus and the children of Cronus where the titans in Greek myth) (Blunck, Solar system moons discovery and mythology, 2010). According to Greek mythology Enceladus was the primary adversary of Athena in the battle between the titans and the gods and at some...

...rub debris against the rock beneath it, also acting like sandpaper. Even plants can force rocks to split as roots creep into cracks and grow. The second type of weathering is chemical Weathering, the breakup of rock caused by a change in its chemical makeup. Rain is the most common producer of chemicals that can weather rock. For example, Rain absorbs carbon dioxide and sulfur dioxide from the atmosphere, forming carbonic acid and sulfuric acid, two liquids capable of dissolving other materials. The levels of carbonic and sulfuric acids in rain, while generally weak, can over time dissolve rock such as limestone, freeing other types of rock. Over very long periods, rain can even dissolve enough limestone to create caves and unusual rock formations. 2.

Earth's Structure

...THE STUCTURE OF THE EARTH The interior structure of the Earth is layered in spherical shells, like an onion. These layers can be defined by either their chemical or their rheological properties. Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of Earth's internal structure is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravity field of Earth, and experiments with crystalline solids at pressures and temperatures characteristic of Earth's deep interior. ASSUMPTIONS: The force exerted by Earth's gravity can be used to calculate its mass, and by estimating the volume of the Earth, its average density can be calculated. Astronomers can also calculate Earth's mass from its orbit and effects on nearby planetary bodies. Observations of rocks, bodies of water and atmosphere allow estimation of the mass, volume and density of rocks to a certain depth, so the remaining mass must be in the deeper layers. Earth's radial density distribution according to the preliminary reference earth model (PREM). Earth's gravity according to the preliminary reference earth model (PREM).

...the asthenosphere, the weaker, hotter, and deeper part of the upper mantle. The boundary between the lithosphere and the underlying asthenosphere is defined by a difference in response to stress: the lithosphere remains rigid for very long periods of geologic time in which it deforms elastically and through brittle failure, while the asthenosphere deforms viscously and accommodates strain through plastic deformation. The lithosphere is broken into tectonic plates. The uppermost part of the lithosphere that chemically reacts to the atmosphere, hydrosphere and biosphere through the soil forming processis called the pedosphere. The concept of the lithosphere as Earth’s strong outer layer was developed by Joseph Barrell, who wrote a series of papers introducing the concept.[2][3][4][5] The concept was based on the presence of significant gravity anomalies over continental crust, from which he inferred that there must exist a strong upper layer (which he called the lithosphere) above a weaker layer which could flow (which he called the asthenosphere). These ideas were expanded by Harvard geologist Reginald Aldworth Daly in 1940 with his seminal work "Strength and Structure of the...

However, traditional methods cannot measure the ancient leaving rates, so a myriad of research attempting to provide explanations were met with unmatched magnitudes. In this paper we consider that the growth patterns on fossils could reflect the ancient Earth-Sun relationships. Through mechanical analysis of both the Earth-Sun and Earth-Moon systems, these patterns confirmed an increase in the Earth-Sun distance. With a large number of well-preserved specimens and new technology available, both the modern and ancient leaving rates could be measured with high precision, and it was found that the Earth has been leaving the Sun over the past 0.53 billion years. The Earth’s semi-major axis was 146 million kilometers at the beginning of the Phanerozoic Eon, equating to 97.6% of its current value. Measured modern leaving rates are 5–14 m/cy, whereas the ancient rates were much higher. Experimental results indicate a special expansion with an average expansion...

Old The Universe

...Approximately 14 billion years ago, the universe that stands today was born. There are various explanations for how it was created. Research shows that they are essential scientific questions and it stimulate scientists to debate their research. Many scientists from all over the world and different time periods work to find the reason behind its creation. The different theories on the origin of the universe have a great impact on the way humans view how the universe was created. The most known is the Big Bang theory and smaller theories include the String theory, the Incredible Bulk theory, the Times Arrow theory and the Steady State theory. (Tate) The universe is almost 14 billion years old. There are two common ways scientists use to calculate how old the universe is. The first method involves measuring the speeds and distances of the galaxies. Scientists interpret that the galaxies were closer together before in the past because all of them are slowly moving further from each other every second. Identifying the current speeds and distances of the galaxies, included with the rate at which the universe is accelerating, permits scientists to calculate how long it took...
