Evidence of Pangaea Pangaea was introduced by Wegener. He found evidence that the seven continents used to be one large continents. The evidence would be the fossils found in different continents. There is also the fact that the continents seem to fit together, the continental puzzle, that supported pangaea. In addition, the Andes Mountains and other mountains that go nowhere are also evidence of pangaea.
The proof of pangaea are the fossils found on the continents. The same species of fossils are found in different continents that are across the ocean. Some of them are land animals unable to swim across the Atlantic or Pacific ocean. Those species also evolved at the same pace. This suggests that those continents used to be close together,
To set the stage, we must go back 270 million years ago when a majority of the earth’s land masses were collected together in a single continent, a supercontinent, named Pangaea (Encyclopedia Britannica, 1). Historian Alfred Crosby explained that this collected all of earth’s land based biology into a single place, creating a single Darwinian “arena for competition” (Crosby, 1). Or in other words, one big evolutionary pot. Crosby also explains that 180 million years ago, Pangea split into two major land masses, what is now the Americas in the Western Hemisphere as one land mass and Euro-Asia and Africa as the second lass mass (Crosby, 1). What was once a single evolutionary pot, was now two, allowing for plant and animal life to take different evolutionary paths. These two worlds remained relatively separate from each other until the arrival of Christopher Columbus and other European explorers. That contact between the old world and the new world brought two distinct evolutionary arenas crashing into each other and returned a majority of the earth’s landmass into a single Darwinian pot, (Crosby, 1) This was Crosby’s re-knitting of the torn “seams of Pangaea.”
Punic wars impact Over and over again, man engages in war with his neighbors, friends, and his enemies. In a good deal of these wars, it was caused by self-important nations that were in the action of making their empire larger and ended up aggravating another superpower or an ally of one. For some fifteen years regarding the defeat of Rome, the tides went back and forth between the two but ended up leading to the victory of the Romans. When the war was over, Rome made some very unpleasant requests and Carthage filled those requests even though some of them were very drastic. The first Punic War started with an offer by the locals in Messana for the Romans to benefit them in defeating the Carthaginians.
The Carboniferous Period was a time period in the Geological Time Scale that came after the Devonian Period and ended at the beginning of the Permian Period. It lasted from 359 to 298 million years ago. The Carboniferous got its name from the large amount of coal deposits that were found during this time scale. In North America, the period is often separated into two, the Mississippian and the Pennsylvanian.
The areas dominated by the Maya are known today as the southern Mexican states: Chiapas, Campeche, Yucatan, Quintana Roo, and Tabasco. The Maya civilization spread all the way through the nations of Guatemala, Belize, El Salvador, and Honduras. A very large expanse of city-states that ruled the area linked by trade routes.
This paper examines a National Geographic news article pertaining to the history of First Americans called, “On way to New World, First Americans Made a-10,000 Year Pit Stop”. The First Americans may have stayed on the Bering Land Bridge after separating from Siberia, which would explain a few things about the genetic variances between the two groups. Why do researches believe first Americans lived on the Bering Land Bridge? Are the reasons to believe in this justified? This paper attempts to answer such questions.
Tectonic plate theory is a relatively new theory that has evolved over the last century. The history of the theory can date back all the way to the twentieth century. Before the 1960s a majority of geologists believed that ocean basins and continents had a fixed position and
In 1993, Universal Studios released an epic movie known as Jurassic Park. Based on the novel by Michael Crichton, Steven Spielberg and his incredible cast took the viewers on an adventure that brought dinosaurs back from the dead and set the bar for how people would expect special effects in a movie should be. The movie was critically acclaimed and won many awards for special effects and sound. Jurassic Park is one of the greatest movies of all time because it brought dinosaurs to life on screen in a way that had never been attempted before plus leading edge audio/video special effects turned the world on its head with their stunning realism and lifelike sound.
Since the beginning of human kind there has been a cloud of wonder of how our planet was formed. Scientist interested in this field through out the years have developed many different theories to how our planet came about. Before the Twentieth Century, scientists and geologists thought that mountain structures were due to the massive tightening of the earth caused by the gradual cooling of molten rocks. In 1900, American scientist Joseph Le Conte, published an article in the Appleton's Popular Scientific Monthly. He described that the problem in understanding mountain building was establishing the cause of sideways pressure. It was not until 1910, that an American Geologist named F.B.Taylor, proposed the idea of a continental drift. Other scientists dismissed Taylor's idea, because there was just not enough proof. However, Taylor's idea was then backed up by a German scientist named Alfred Wegener. He proposed that the continents surrounding the Atlantic Ocean, Africa and South America fit together like a jigsaw puzzle. His broad range of studies enabled him to incorporate his theory of Plate Tectonics. Wegener, later in 1915 while in the German military published his idea that interpreted how his continental drift theory worked. He proposed that a huge landmass called Pangea, meaning ("all land") existed 200 million years ago. He furthered explained that this super continent began to drift apart very slowly throughout millions of years into what it looks like now. Wegener went on several expeditions through out his life to the continents of South America and Africa.
There is also information presented in the ways that we can study the earth and what is left on our earth that explain evolution in a way that I feel like is undeniable. Examples of evolution can be seen in fossils, of layers deposited on the earth, of radiometric dating, and the Mid-Atlantic ridge. All of these different evidences lead us to believe in an old earth. A earth that has been around roughly 6.5 billion years and has changed and grown while preserving sight into our
The Permian Period was the last period of the Paleozoic Era. During this geological time period’s earlier stages glaciation was extensive. Middle Permian began to warm, and by the late Permian the environment was hot and dry. The environmental conditions were so extreme that the marine and terrestrial life forms were greatly affected. According to research the drastic climate change could have been caused by the formation of Pangaea. In 1912 Alfred Wegener while studying his theory of the continental drift, discovered Pangaea’s very existence. A combination of all of Earth’s landmasses joined together and covered 1/3 of Earth’s surface. Pangaea was f...
Terra Nullius which is referred as “land belonging to no one” was an obstacle in order to achieve Native Title which is the right to land by the original inhabitants, as the Indigenous people had to prove that they were traditional owners of the land with an ongoing connection to it in order to claim native title, which was difficult as they had been forced off their land almost 200 years before. In order to achieve the native title, it had to be claimed by people with the ancestors that inhabited and associated with the land before the European settlement.
Old earth proofs: Most scientists accept these indicators, and many more like them, as proof of an old earth and universe. However, those scientists are forced to make a basic assumption: that naturally occurring processes and fundamental constants in the past behaved in the same way as they do today. For example:
Atlantis was a continent of the Atlantic Ocean where, according to Plato, an advanced civilization developed some 11,600 years ago. Plato affirms that, as the result of a huge volcanic cataclysm of worldwide extent, this continent sunk away underseas, disappearing forever. Official Science - the one you learn at school - rejects the actual existence of Atlantis, as it has so far been unable to find any traces of its reality. But the reason for that is simple to explain. Everybody has been looking in the wrong locations, as Atlantis indeed lies in the opposite side of the world. So been told, of course…
Continental drift is the theory of the shifting of the positioning and look of continents in the past and their predicted look in the future. 2.5 cm a year doesn’t seem like a lot unless we calculate it in the millions or hundreds of million years, possibly even 200 million years ago, the era of Pangea. Pangea is the theory that all the 7 continents that we have classified today were joined into one supercontinent, Pangea. The main evidence for this theory of continental drift and Pangea is that almost identical animal and plant fossils, and similar rock formations, are found on different continents. The coastlines of continents even match up with a little bit of rotation and alignment. Through the years, parts of the supercontinent started to drift apart and continued drifting to turn into the continents we know
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
