Alfred Wegener Research Paper

2. The theory of “Pangaea” exists suggesting that the continents were once nestled together into one mega-continent. The continents then spread out as drifting islands.

The theory of Pangaea suggests that the continents were once stuck together into one huge continent. Eventually they started drifting into separated landmasses, which gave birth to the modern continents.

Alfred Wegener claimed that the Earth used to have only one giant continent called Pangea, and that it broke up into pieces and they drifted away. Fossils have the most evidence to prove because they show that the continents that would be connected contained fossils from one another. One example of this is in America and Africa, they both had the fossils of a dinosaur that couldn’t swim. One other major reason is the ancient climate, there was a fossil of an ancient tropical plant in Antarctica the theory of Pangea would help explain this. Finally, parts of the Appalachian Mountains in the U.S., Greenland, and Western

Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the theory of the continental drift. Wegener theorized that at one time the continents were one large landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It was not until long after Wegener’s death that proof was obtained and his theory verified.

Alfred Wegener claimed that the continents were once attached and slowly drifted apart. The evidence that best supports Wegener’s claim is the fit of continents because North and South America’s edges look like they would fit almost perfectly with Europe. Another Example of strong evidence for Continental Drift is the mountain ranges because the Appalachian mountains look like they match with Greenland, Great Britain, and Scandinavia’s mountains. The final convincing piece of evidence for Continental Drift is how some places have the same rock types as other places that are far away. All the evidence leads us to know that the continents were once attached.

James Hutton was the first scientist to address the Earth was millions of years old, as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism, and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of the first to recognize and have an understanding of how the Earth works which required data and information from earth sciences. In the 1960s, the theory for the continental drift became known as the theory of plate tectonics or plate building.

Alfred Wegener suggested that the continents have moved about the earth. Wegener carefully compiled evidence for continental drift that eventually became universally accepted in the scientific community. This lab also helped support the theory of continental drift. In this lab, we created a map of Earth 225 million years ago. This map indicates that South America, Africa, India, Antarctica, and Australia all used to be a part of a landmass called pangaea.

Throughout history, scientists have made several theories about every scientific issue. There have been arguments and rebuttals to every theory from creation to lost civilizations. One theory that has survived is that of the continental drift, which theorizes that the continents as we know them today once were combined to form larger land masses. Those land masses then split apart and moved from tectonic plate shifting into what we know today (Abbott 2013). A well known scientist and large supporter of this theory was the German meteorologist Alfred Wegener (Abbott 2013). Around the close of the First World War, Wegener published his findings supported by samples of fossils and rocks. These samples were collected from opposing sides of the

This passage, "Continental Drift", explains what continental drift is, evidence to support it and plate tectonics. Alfred Wegener and Frank Taylor suggested a theory that at one point in time, all the continents were one very large continent called Pangea in 1912. This giant supercontinent was surrounded by one large ocean called Panthalassa.

In the early 1900´s, Alfred Wegener developed a hypothesis called the continental drift. This hypothesis states that All continents Were once joined together in a single landmass. Over time, All continents drifted apart Called the continental drift.This Paragraph will state 4 Types of evidence why Each piece of evidence supports the claim.

In the 20th century, there was a scientist named Alfred Wegener, who came up with a theory that all the continents were one single continent, mostly known as the Continental drift. There was plenty of evidence to prove that this actually happened. Look at the eastern coastline of South America and the western coastline of Africa. Does it look like it fits kind of like a jigsaw puzzle? If so, they might've been connected tougher at some point. Even the fossils found there are evidence of this happening. If you look the image here, you see that the fossils line up toge-

The second theory was Alfred Wegener’s theory. He thought that the continents were moving. He based his argument on the observation that the coast lines matched up like puzzle pieces. He also observed that similar fossils were found oceans apart. He tried to explain this by something called continental drift. So, Alfred Wegener’s theory was that during some point in history, the plates moved from one giant supercontinent to where they are now.

Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener’s ideas by using the evidence of seafloor spreading to explain what moved continents. The theory of plate tectonics is what brings together continental drift and seafloor spreading. Plates are made of lithosphere topped with oceanic and/or continental crust. The plates are moved around on Earth's surface by seafloor spreading. convection in the mantle drives seafloor spreading. Oceanic crust is created at mid-ocean ridges. The crust moves outward from the ridge over time. The crust may eventually sink into the mantle and be

Continental drift all started with a theory that all the continents were connected called Pangaea, becoming a super-continent this was discovered by Alfred Wegener a polar researcher, Geophysicist, and a meteorologist. It was first proposed in 1912, and Alfred says this occurred around 299 million to 273 million years ago but the super-continent started to break apart 200 million years ago. The most popular and major evidence for Pangaea was that some of the continents fit perfectly together. The most noticeable continents were North Western coast of Africa and the Eastern coast of South America, theses two looked like they could been once connected. Another piece of evidence is the distribution of fossils, archaeologists have been discovering

However, Wegener believed that only the continents were moving and they plowed through the rocks of the ocean basins. (Colliers Encyclopedia, 1996) Harold Jeffreys then argued that it is impossible for continents to break through solid rock without breaking apart. (USGS, 2012) Wegener also claimed that the centrifugal force of the spinning planet had forced the continents sideways, parallel to the equator; tidal pull from the sun and moon had caused lateral movement. (Sant, Joseph, 2012) His orders of magnitude were too weak. Thus, his theory was dismissed. (Lois Van Wagner, 2013)
