Argumentative Essay: Is The Earth Flat?

Ptolemy, a Roman astronomer came up with the theory that the universe revolved around Earth and all the creatures inhabiting it (Doc. C). This theory, The Geocentric Universe of Ptolemy, was adjusted by most of the people during The Middle Ages. However, much later on, Nicolaus Copernicus, a Polish astronomer, disagreed with Ptolemy’s theory. With his use of math and reason, he came up with a new theory called The Heliocentric Universe of Copernicus (Doc. C). He said that the universe & Earth itself revolves around the sun. The Church denied this theory because they did not want to be proven wrong. If the Church was wrong about this part of the universe, this would then cause man to wonder what else they could be wrong about, or even lied to them about. This new theory taught men to think for themselves and not to rely on the Church for

For years the Earth was thought to be flat. The groups of people that created and developed this theory were heavily influenced by religion and cultural practices that were prominent at the time. The theory was a way to explain the Earth and it made sense in the explanations people could create. After many years of scientific exploration and technological development this theory was disproven. The new theory was that Earth is a sphere. However, even after the observations of a spherical Earth the flat Earth theory is still around and widely believed today. This theory is different depending on the group of people present. According to Chris Fleming, “Different cultures at different times have posited a staggeringly diverse array of

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

Columbus’ postulation that the world was not flat because any educated person in that time new that the world was round.

We have learned in basic K-12 schooling that the Earth is spherical in shape. The earliest recording of this concept was c. 6th century BCE in ancient

(between June 20th and June 22nd) the Greek Astronomer, Eratosthenes had heard of a famous well in a Egyptian City called Syene (now known as Aswan) located around the Nile River. He knew that every year on the solstice, there was no shadow on the bottom of well but instead the rays of sunlight reflected back, and not on the sides of the well as on other days. He came to a conclusion that the sun was directly overhead in Syene at noon every year. He knew that in his hometown Alexindra, the sun was never directly above him even on the solstice. He assembled a pole in Alexindra to study and calculate the shadows position eventually proving that no sun was directly above but faintly south. Knowing that the earth was curved and knowing the distance between the two cities, Syene and Alexandra he calculated the planets circumference by doing simple geometry. “Eratosthenes could measure the angle of the Sun’s rays off the vertical by dividing the length of the leg opposite the angle (the length of the shadow) by the leg adjacent to the angle (the height of the pole). This gave him an angle of 7.12 degrees. He knew that the circumference of Earth constituted a circle of 360 degrees, so 7.12 (or 7.2, to divide 360 evenly by 50) degrees would be about one-fiftieth of the circumference. He also knew the approximate distance between Alexandria and Syene, so he could set up this

It was to be that educated Europeans already believed that the world was round even before Columbus made the statement that the world was round. It was the Idea that the Greeks in the 5th century BC already came up with the myth that the world was round. Most believed that the world was flat and you could sail right off the earth. These people thought this because the maps that they used to navigate where a world that was flat and this is why they thought this. But studies identified the world as in a sphere but no christopher columbus was not the first to have estimated that the world is a

Ancient cultures did not believe the Earth to be the spherical object we know Earth to be

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves

Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).

Climate change has undoubtedly become one of the most prominent debate topics in the world today. With that being said, there are multiple aspects of climate change currently being discussed; causes of climate change, the idea that climate change may be a hoax, and whether or not climate change affects human health are three of the many ongoing debates about climate change. Climate change is surrounded by negative connotations, but Jay Leno, former host of NBC’s The Tonight Show, shed some light on the darkness of climate change, saying "According to a new U.N. report, the global warming outlook is much worse than originally predicted. Which is pretty bad when they originally predicted it would destroy the planet.” Although his first statement is rather true, Leno manages to lighten its load with a less true, but hilarious, comment. His words force one to realize that climate change impacts everyone in any area of the health triangle, whether it be through a joke such as Leno’s, or directly through issues such as pollution and pollen; the areas of the health triangle include physical health, mental/emotional health, and social health. Therefore, climate change is a threat to all aspects of human health; social health, mental/emotional health, and physical health.

“There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” - Barack Obama. Climate change has been a popular topic of discussion, because of the threat to our environment. The world will forever be changed if climate change isn’t taken into serious consideration and not in a good way. Climate change has been a popular topic of discussion, because of the threat to our environment. Climate change has had many negative effects, for example, damage to coral reefs, the increase of wildfires, and most importantly rising sea levels. The damage to our earth cannot always be undone nevertheless it can make some things disappear forever.

Global warming, we see it as sad polar bears hopelessly swimming for their lives in the ocean. It's shown as rising sea levels that can washout entire cities. It even sometimes gets turned into politics but scientifically, what is the definition of global warming?

Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
