Comparative Essay Original Creation of the Earth

...Elements of Earth Science Comparative Essay Original Creation of the Earth Rhonda L. Carter 9 March 2014 PHSC 210-B13 LOU | | Introduction It should be easy to say that the Earth was created by a higher power. For a Christian this higher power is God. The Bible gives us the six day creation of the heavens and the Earth and all that dwell upon it. For anyone else, the higher power is some unknown power that science is still trying to figure out. There are a lot of theories in science about how the Earth was created. One of these theories is the big bang theory. The essay will compare the two theories and show how different they are. Old Earth View In the old Earth view of the original creation of Earth we are told about the big bang theory. In order to explain this theory one must understand what science says that it is. “According to the big bang theory, the universe began by expanding from an infinitesimal volume with extremely high density and temperature. The universe was initially significantly smaller than even a pore on your skin. With the big bang, the fabric of space itself began expanding like the surface of an inflating balloon – matter simply rode along the stretching space like dust on a balloon’s surface.” (Takahashi, 2000) When dealing with science, one can see that scientists do not believe in a divine power such as God. They deal with their theories and will tell you that they believe something was created, but not that it was created by God.......

...how well they understood the information presented. While administering the pre-test, I told the students to do their best, but this test was not going in the grade book. This released some anxiety from the students, and they relaxed as they took the test. Some of the students were overwhelmed by the test, and continuously complained about how they didn't know about the information on the test. I reassured the students that the test was only for practice to see how much they knew about science instruments, magnets, and the planets. On the pre-test, the students performed poorly. The students were not familiar with the science instruments listed on the test. The post-test was a great success! A majority of my students passed the test with an A or B, and only a few made a C or below. I would be sure to have a blank for the planet Pluto on the test. Some students didn't like the fact that Pluto was left off the test even though we have discussed that Pluto is no longer a planet. I feel it is important to reiterate the importance of Science and how it is ever changing. When administering the test, the students took about 10 to 20 minutes to complete the test. The classroom was very quiet, and each student had a guard up around their desk so there would be no cheating. On the pre-test, out of 24 students 2 scored B's, 5 scored C's, 16 scored D's, and 1 scored an F. On the post-test, out of 24 students, 17 scored A's, 5 scored B's and 2...

Dating the Rocks of the Grand Canyon (Old Earth vs. Young Earth)

...Introduction This is a comparative essay and its purpose is to compare old-Earth and young-Earth viewpoints on Dating the rocks of the Grand Canyon. There are different views on this and no scientific method that can prove (completely) the age of the universe or the earth. There are the use of different types of calculations that can provide some guesses on the age of the earth. Many things need to be assumed such as a beginning date and the speed of change along with varying increases and decreases of material over time. “Young-Earth Creationism” (YEC) is based on a precept that earth and the universe were created by God, only 6,000 years ago in six days. Their position is that by examining geological records the scientific details of early history will become clear and a literal biblical view of Earth’s creation supported. Now, “Old Earth Creationism” (OEC) is also based on a precept that earth and the universe were created by God, but they also believes and interprets the book of Genesis differently. OEC try to fit cosmology and theories on evolution in (in some form). Both “Young-Earth Creationism” as well as “Old Earth Creationism” believes in a creator. The biggest area of disagreement is the age of the universe and the earth. This essay will look at both “Young-Earth Creationism” and “Old Earth Creationism” in regarding Dating of the rocks in the Grand Canyon. The Grand Canyon is one of the most popular areas in the world to focus on this debate. There is a great deal...

Understanding Science

...Understanding Science For many people, science is something to be dreaded – boring math problems and pointless information. Science, however, plays an important part in the world around us. Not only does science rule every part of the human life, from the inner workings of the body to DNA, but it also explains the world that we live in. Even though, many times, science is looked at as an annoying extension of math and, therefore, something to be despised, understanding it can be extremely helpful in understanding our own lives. Science allows us to understand and answer the big questions that cause many people to turn to religion and their beliefs. Science is a way of understanding the world through examination and testing. It can be defined “as the process of observing and questioning the world around us. We also sometimes call the things that we learn through experimentation science” (Red Orbit). As such, science is the process of studying and testing theories to create a hypothesis. It is a very broad subject matter and encompasses many branches, most ending with the –ology suffix, meaning the study of. Biology, for example, is the study of the life where Geology is the study of the earth. People that study biology and geology are scientists because they follow the scientific method, “the most powerful method ever invented by humans to obtain relevant and reliable knowledge about nature. In fact, it is really the only method we have for discovering reliable knowledge......

Earthquakes

...as long as people have inhabited the earth. These dangerous acts of the earth have been the cause of many deaths in the past century. So what can be done about these violent eruptions that take place nearly without warning? Predicting an earthquake, until now, has almost been technologically impossible. However, with recent improvements in technology and science, many lives have been saved and many more will be. What is an earthquake and how do they occur? Did you know that most of the famous mountains are a result of an earthquake? (Cosmeo, 2008) That tidbit of information was just a little side note; now back to the paper. Earth is a planet that is made up of multiple layers. These layers include an inner layer and an outer layer and layer in between. The inner layer of the earth is a ball of molten rock that rotates within the earth. The other layers that are on top of the inner layer are floating about as a pliable ball of molten rock. The outer layer is what we refer to as the crust. The crust is very thin when compared to the other layers of the Earth. For example, think of the outer layer of an orange as it relates to the interior of the orange. This example relates closely to what the Earth looks like when we examine the crust. The crust and other layers floats upon the mantle core. The crust of the earth is made up of multiple pieces. Each of these giant pieces is called a tectonic plate. What are the events that cause the Earth to quake and shake? The movement......

...definition of Earth Science? All sciences that seek to understand Earth and it’s surrounding space. * What are the sub-disciplines of earth science (geology, meteorology, oceanography, and astronomy)? Know the definition of each of these. Geology is the study of Earth divided into two broad areas –Physical and historical. Physical Geology examines the materials comprising earth, Historical Geology is to understand the origin of earth. Meteorolgy is the study of the Atomosphere and the processes that produce weather and climates. Oceanography integrates chemistry, physics, geology, and biology. It includes the study of composition and movements of seawater, as well as coastal processes, seafloor topography, and marine life. Astronomy is the study of the universe. * Be able to name and define each of the earth’s “spheres” (geosphere, hydrosphere, atmosphere, biosphere).The Geosphere (Solid-Earth) lies beneath the atomosphere and the ocean. It extends from the surface to the center of the planet 6400 Kilometers of depth. The largest of all Spheres. The Hydrosphere is a dynamic mass of water that is continually moving, evaporating from the oceans to the atomosphere, reaching land and flowing back to the ocean. Blankets 71% of the earth’s surface. Depth of 3800 meters. The Atomosphere is the life giving gaseous envelope. It is a very shallow layer. The energy exchanges between the atomosphere and space produces weather and climate. Biosphere includes all life on......
