Tectonic drift theory: the continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations. Alfred Wegener first supported continental drift.

    Lesson 1.06 Flvs Marine Science

    -The relationship between continental drift and the formation of the Earth’s Oceans stems from plate movement that occurred on Earth. There is a theory that all the continents were once all one big piece of land named Pangaea, and over millions and millions of years the land of Pangaea started to split apart into many different continents. It divided Panthalassa, the large global ocean that surrounded the supercontinent Pangaea, into many different oceans instead of just one big one and now we have many various oceans around the world.…

    Plate Tectonics Theory

    The plate tectonics theory was put forward by Alfred Wegener suggesting that the continents were at one point all conjoined in one supercontinent known as Pangaea. He then said that Pangaea had drifted apart through the movement of plates to give us the current places of continents we have today. Wegener's theory was linked to a variety of evidence, however it took further research and evidence for this to become a leading theory. This means that although volcanic and seismic events help to prove the plate tectonics theory valid, there is also a range of other factors involved.…

    The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses.…

    Evaluate How Plate Tectonics Theory Helps Our Understanding of the Distribution of Seismic and Volcanic Events

    Pangaea was a supercontinent that formed around 300 million years ago and began to break apart around 200 million years ago, during the times of the Pangaea of the land was on one continent and all of the sea was one giant ocean. This theory was coined during a 1927 symposium discussing Alfred Wegener’s theory of continental drift, he posed the idea that prior to the breaking up and drifting to their present locations, all of the continents had at one time been a single supercontinent as seen pictured on the right. The breaking and forming of the supercontinents appears to have been cyclical through the Earth’s history. Alfred Wegeners theory talked about how icebergs may behave the same as moving continents, and how therefore plate tectonics caused the movement of continental crust.…

    Evaluate How Plate Tectonic Theory Helps Our Understanding of the Distribution of Seismic and Volcanic Events (40 Marks)

    The Plate Tectonic Theory developed in the late 1960’s, when people noticed how continents either side of the Atlantic Ocean seemed to almost fit together. Francis Bacon, an English Philosopher was aware of this as early as 1620. Topographical and geological evidence built up and allowed Alfred Wegener to publish a theory in 1912, suggesting that the continents were once all joined together in a supercontinent he called Pangaea. Wegener proposed that at some time, the land masses had drifted apart until they occupied their current positions on the globe. There was lots of evidence to support his theory including Continental Fit. Sometimes continents, such as the west of Africa and the eastern seaboard of South America, seem to fit together if placed beside each other. This is particularly true is the continental shelves are taken into account as the true edges of the land masses. There is also Geological Evidence where rocks of the same age and type and displaying the same formations, such as in south-east Brazil and South Africa. The trends of the mountains are also similar in eastern USA and North-west Europe. Similar glacial deposits are found in Antarctica, South America and India, which are now many kilometres apart. Climatological Evidence shows that places as far apart as Antarctica, North America and the UK all contain coal deposits of a similar age that were formed in tropical conditions. They are no longer in tropical climate zones and must have drifted apart since the Carboniferous period. Biological Evidence shows that similar fossil formations are found on either side of the Atlantic. Plant remains from humid swamps that later formed coal deposits have been found in India and Antarctica.…

    “Volcanic and Seismic Events Are Major Pieces of Evidence Towards Proving That the Plate Tectonic Theory Is Valid” Discuss the Extent to Which You Agree with This Statement (40).

    In 1912, Alfred Wegener, a German meteorologist, was the first man to state that the continents were once joined in a super continent called Pangaea, conversely he couldn’t explain why and what happened to cause the plates to move apart. He based his theory on the extraordinary fit of the South American and African continent coastlines. Notably the eastern edge of South America and the western edge of Africa showed very similar geological features suggesting that at some point in the Earth’s history the landmasses were joined together. Another indicator that the continents were once distributed differently was geological evidence of glaciations in India – it is unlikely that glaciers could ever reach such low latitudes, but this problem can easily be explained by the theory of continental drift. Fossil distribution also provided some of the earliest evidence for plate tectonics. Interestingly, plant and animal fossils were found on the matching coastlines of South America and Africa. These are now widely separated by the Atlantic Ocean, therefore he reasoned that is physically impossible for most of these organisms to have swum or have been…

    Student Exploration: pH Analysis

    The strength of an acid or base is measured on the pH scale. The term “pH” is short for “potential of hydrogen.” It is a measure of how many excess H+ ions there are in a solution. The pH scale runs from 0 to 14, with 0 representing the highest concentration of hydrogen ions. Acidic substances have a pH below 7, while alkaline substances (bases) have a pH above 7. Pure water has a pH of 7 and is considered neutral.…

    Continental Drift, Plate Tectonics, the North American Plate

    Continental drift is when the Earth's plates move in different directions. Scientists think that Continental Drift is caused by the heating and cooling of the Earth's mantel which makes currents. These currents make the plates slide and move over the liquid and molten rock in the mantel. These currents made by the heating and cooling are called convection currents. The person who developed the theory of continental drift was named Abraham Ortelius in 1956. He thought of this theory by noticing that the land of South America seemed to fit Africa like a jigsaw puzzle. He then thought up that the land must've been torn apart by earthquakes and floods. Later on Alfred Wegener made a fully developed hypothesis on how the continents came to be where they are today. This was that the Earth's crust was once a supercontinent known as Pangeae. But the continents broke off not by earthquakes and flooding as Abraham Ortelius stated, but by volcanic activity due to thermal expansion. Then the new continents drifted by further expansion of the rip-zones. But then a theory without any expansion involved was developed by Frank Bursley Taylor. He proposed that the continents were dragged towards the equator by a lunar gravitational pull. But both of these theories were wrong, as I mentioned before, the continents move by convection currents in the mantel. This idea was founded by geologist Arthur Holmes. This is what continental drift is.…
