Some people might know about the Earth, but what about the solar system? Earth Science and Astronomy are similar in many ways and can be linked together. The basic fact that the Earth is a part of the solar system is the biggest key to it all. Through the study of our Earth, we are able to get a better perspective of how the universe works. So how did the Earth come to be? How did the evolutionary life cycle of the solar system start out and how did it bring us to where we are at today?
Scientists believe that the formation of the universe started with the Big Bang Theory and the universe was an enormous compacted hot and dense mass. Roughly 13.7 billion years ago, the dense mass of the universe began to expand and cool and formed the first elements of hydrogen and helium. Eventually those elements coupled with dust and matter from dead stars, began to form the solar nebula which was a giant rotating cloud. About 5 billion years ago the gravitational interactions of the particles of gases and dust caused the solar nebula to start rotating and caused it to flatten and spread...
Matter, as we conceive it today, did not exist after the Big Bang, because the temperature was too high for that. While trying to join protons and electrons, light continually crossed apart. Only when the universe had cooled to 3,000 K, the atoms are held together and the light was beginning to happen.
Our Solar System was formed approximately 4.6 billion years ago during the Big Bang with the collapse of an interstellar body (Lammer et al., 2009). During these supernova explosions, the dusts and gases that were expelled were mixed and processed to form the planets of our system (Lammer et al., 2009, Nisbet and Sleep, 2001).
After Sir Charles Darwin had introduced his original theory about the origins of species and evolution, humanity’s faith in God that remained undisputed for hundreds of years had reeled. The former unity fractured into the evolutionists, who believed that life as we see it today had developed from smaller and more primitive organisms, and creationists, who kept believing that life in all its diversity was created by a higher entity. Each side introduced substantial arguments to support their claims, but at the same time the counter-arguments of each opponent are also credible. Therefore, the debates between the evolutionists and the creationists seem to be far from ending. And though their arguments are completely opposite, they can co-exist or even complement each other.
The Big Bang Theory is one of the most important, and most discussed topics in cosmology today. As such, it encompasses several smaller components that attempt to explain what happened in the moments after creation, and how the universe we know today came from such a fiery, chaotic universe in the wake of the Big Bang. One major component of the Big Bang theory is nucleosynthesis. We know that several stellar phenomena (including stellar fusion and various types of super novae) are responsible for the formation of all heavy elements up through Plutonium, however, after the advent of the Big Bang theory, we needed a way to explain what types of matter were created to form the earliest stars.!
Native Americans possess a greatly different spirituality than our culture has today. We have varying beliefs, values, and traditions that we deem as normal. If the current generation had to change its way of life to mimic the natives, there would be several potential benefits for ourselves and Mother Earth. There would be considerable changes in role of nature within our lives, the foundation of relationships, and the meaning of connotation of power that would be the cause of a complete paradigm shift throughout the population.
It all started 13.7 billion years ago in the core of a black hole which contains large amounts of gravitational pressure which can squish very fine particles. After the big bang happened the universe eventually cooled and expanded. Every day the universe expands, so trying to find the end will be impossible. Our universe is similar to filling a balloon with air until expands, while keeping all of its contents inside.
If you were told to believe a side of an argument that did not have majority of evidence points on its side, would you? The theories of evolution, creation and intelligent design have been a debated controversy for years and years. These three theories have three different ideas. The theory that creationists have is to believe that concept and design require a Creator. Creationists usually tend to believe that each organism is created as a single and distinct organism. Evolutionists tend to believe that all life started from single celled organisms. They believe that these single celled organisms are part of a continuing evolution over a very long period of time and that this evolution results in the development of new varieties and different species. People who believe in intelligent design believe in the theory that the universe cannot have arisen by chance and was designed and created by some intelligent entity. Evolution is the theory that is most probable because of the fossil record, similarities in all organisms and genetic changes in a population over time.
The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000 years later that it cooled enough so that hydrogen and helium could form by fusion processes. Even then, it took another two billion years of cooling for enough clumps of interstellar dust and gas, called molecular clouds, to achieve stability in the universe.
Our sun is the central pivot point to which or entire planet and solar system is built around. With out it all life on our planet would cease to exist. Within this paper we will explore how our Sun and solar system formed and came to resemble what we see today.
Other changes are more gradual but much more dramatic when viewed over long time scales. Powerful telescopes reveal new stars coalescing from galactic dust, just as our sun did more than 4.5 billion years ago. The earth itself formed shortly thereafter, when rock, dust, and gas circling the sun condensed into the planets of our solar system. Fossils of primitive microorganisms show that life had emerged on earth by about 3.8 billion years ago.
When people think of geology, they usually think of rocks and fossils. However, geology is actually a very large field of study. The knowledge of geologists ranges from rocks and fossils to the moon and other planets (Hammonds 7-8). Geologists use a variety of subjects in their work, but the sciences and math are the most important. Some of the sciences geologists study are physics and chemistry (12). English is also a subject that geologists use when communicating with other scientists, the media, and the public (12) . Because of these tasks, it is important for geologists to have a wide knowledge of these different subjects.
Generally, the universe began as a composition of radiation and subatomic particles, which proceeded with galaxies formation. Galaxies are made up of hydrogen, helium, 100-200 billions of stars, planets and most having a black hole at the center, which attracts everything present in galaxies by force of gravity. Galaxies can be classified as either spiral (Milky Way- galaxy which human kind has been found to exist), elliptical, lenticular and irregular, where the structure is determined by neighboring galaxies with most galaxies are moving away from each other. Classification of galaxies is being conducted by online programs such as Galaxy zoo, using pictures from telescopes and is making significant progress.
The big bang theory is an attempt to explain how the world began. The big bang theory begins with what is called a “singularity.” This term is used to describe an area in space which defies all the known laws of physics. Singularities are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that matter is pressed together into an infinite amount of pressure. The dense hot mass of the singularity slowly expanded. This process is called inflation. As the singularity expanded the universe went from dense and hot to cool and expansive. Inflation is still continuing on today which means that the universe is continually expanding.
Earth system refers to the earths interacting physical, biological, and chemical processes. The system consists of land, oceans, atmosphere and poles. The earth system has four spheres, including the geosphere, the hydrosphere, the atmosphere, and the biosphere. The geosphere refers to the solid parts of the earth system, including earth’s rocky crust, mantle, and the metallic core. Within the geosphere is the lithosphere, which only refers to the uppermost layers of solid earth. The uppermost layers of solid earth are the oceanic and continental crust rocks. Just below the crust is the mantle, which is composed mostly of magnesium and iron silicate minerals. The mantle accounts for about 2/3 of the
The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen, helium, and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together, protoplanets, to eventually form planets. A great mass of the material eventually began to form together, protosun, and make up the sun.
