Pange Plate Tectonics

The first, would be Land features. Alfred Wegener saw how the coal fields in North America and Europe lined up, he also realized that mountain ranges in North America and Africa lined up. The second, evidence he used were the fossils. There were three types of fossils he found the first was the glossopteris a fern like plant found in Africa, South America, Australia, India, and Antarctica. The second and third were the Mesosaurus and the Lystrosaurus fossils, they were freshwater reptile fossils on continents separated by oceans. The third evidence Alfred Wegener used was, the climate zones. Alfred Wegener looked at the past of the climates and he found scratches in rocks from glaciers in South Africa. Those were the three main evidences Alfred Wegener used to prove Continental Drift

Continental drift is the theory that says the continents are moving around on the Earth’s surface, both in the past and now. A man named Alfred Wegener noticed that South America and Africa looked as though they could fit together. Scientists were convinced that it was once a big landform. Research was conducted to find that North America, South America, and Africa fit together. Since the Earth's crust solidified billions of years ago, plates of its crust have been drifting. The map of the Earth is always changing too. In addition, not only are the underlying plates moving, but the plates change in size. Also, the sea level changes over time (as the temperature on Earth varies and the poles melt or freeze to varied extents), covering or exposing

Plate tectonics is the theory that has been studied for over thirty years that states that the outside layer of Earth are actually large plates, approximately forty kilometers thick, that slide across the magma beneath the exterior of the planet. The theory of plate tectonics explains the enormous amount of volcanic and seismic activity surrounding certain areas of the world, stating that the sliding of these plates either away from each other, sliding past each other, or sliding into each other and causing one of the plates to slide beneath the other. When the plates slide away from each other, new ocean floor is formed. When the plates slide past each other, minor earthquakes will occur. When the plates slide toward each other and

Much proof of the evolution of organisms and change in the environment overall is shown through fossils. Some of the most unusual fossils found in Australia were disovered at Riversleigh. Animals such as the Lungfish show a strong development in animals as adaptations are cleary seen through, for example, the fact the the lungfish has developed, working lungs that it can us to breathe with on land unlike any other fish. The lungfish shows the tranformation of fish swimming only being ablt to live in water to fish adapting and being able to live on land whilst their body has become dry in the dry season. It shows the evolution from sealife to land life and shows inbetweens for the evolution of the creatures. There are also records of many ancestors of animals that walk the earth today. examples include primative koalas and wombats, a range of ancestral thylacines and platypus, aswe as rodents whch show the evolution of placental mammals. Many of these organisms evolved from what they were and adapted as the climate changed to suit more and became the animals we see today. many similar types of flora and fauna fossils as well as the formation of rocks are similar so due to the continental drift. the continental drift is the drifting apart of all continents from one full land mass into the locations they are currently in. all landmasses were original joined as one big land mass caled 'Pangaea', because all organisms existed on a single land mass aswell, similar fossils can be found, as can rock formations. some evidence of continental drift was that a man named Alfred Wegener went out and matched up the same rock ike a puzzle with different pieces from different parts of the world and they

There are many similarities and differences between continental drift, seafloor spreading and plate tectonics. All three of these theories have yet to be proved correct. But the evidence is sound so therefore it is regarded as the truth. Plate tectonics is a more recent and detailed theory than continental drift. Seafloor spreading is caused mostly because of what occurs in the other two theories. All three theories work together to help us understand the Earth.

Questions were raised when rocks were found on the surface of the Earth that had manetization the did not corralate to the location that it was found. Also, Harry Hess suggested that the continents could have drifted and still were because the sea floor was moving much like a conveyor. (Bugielski, 1999).

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.

Alfred Wegener gave many facts that help prove his Continental Drift theory. Wegener’s supporting facts include fossil evidence, land features, climate evidence, and sea floor spreading.

1. What is continental drift? Continental drift is the gradual movement of the continents across the earth’s surface through geological time.

How can we tell if tectonic plates move and if the earth was once one huge land mass? Scientist Alfred Wegner produced three pieces of evidence to support The Theory of Plate Tectonics. Due to modern technology, we are able to have a greater comprehension of his research. One of his three documentations refers to the fact that certain continents have coastline similarities. For example, the east coast of South America and the west coast of Africa have comparable forms. This led him to believe they were once connected to each other. The second piece of evidence states that fossils of plants and reptiles were similar. Two of the similar fossils found consist of the following the Mesosaurus, a reptile fossil, and the Glossopteris, a plant fossil. These fossils were found across the southern continents or Pangea. The third piece of evidence consist of the fact that similar geologic patterns of rocks

Geochemists are continuously concerned in defining elemental abundances in minerals and rocks as the time goes by. They examine the distribution of chemical elements and the movement of these elements into soil and water systems which they find interesting in having a closer look on the evolution of the Earth and how it affects the plate tectonics. The movement of the plates caused the supply of nutrients to the oceans changed through the time. To further know what might have helped trigger the rise in atmospheric oxygen, Greber lead a group of researchers to look at Titanium isotopes in shales which lead to a conclusion that changes in crustal composition are possibilities that in an extent can affect the prevalent change in ocean chemistry.

3. Continent to continent is called convergent and what happens is the plates come together

Almost two-hundred million years ago, all of the earth's continents formed an immense supercontinent, Pangea. The land that made up Pangea formed on several different geological plates instead of just one plate. This caused Pangea to break apart into several different continents. After the continents broke apart, they started to move away from each other. Alfred Wegener and Frank Taylor, a pair of scientists of 1912, first developed the "Continental Drift" theory. While this occurred about two-hundred millennia ago, continental drift still happens today, but people can't feel it. Even though the continents can't be seen moving, evidence proves that, in fact, the continents still drift around today. Scientists have found multiple pieces

Based on the information in the textbook and the instructor note, plate tectonics is the Earth’s surface divided into several plates that move slowly and change in size. I found the video Plate Tectonics: “Birth of a Theory” in session 13 very useful. It helps me understand the material easily by using the animation to illustrate the process of plate tectonics. It is amazing about the fact that the continents can be made to fit together like pieces of a picture puzzle. About 225 million years ago, the Earth seemed to contain only one piece of continent. However, as time goes by, the plate boundaries have happened. The plates that move away from one another are called divergent plate boundaries. The plates that move toward each other are called

"Continental Drift" talks about the theory of plate tectonics, which states that the entire world was once a gigantic supercontinent which then drifted apart due to large continental and oceanic plates. These plates can move anywhere, taking whatever is on top of it with. Sir Francis Bacon first came up with this theory in the 17th century when he saw that the coasts of South America and Africa seemed to fit together. In 1912, Alfred Wegener proposed that we can from one continent he named Pangea.
