  • Antonio Snider-Pellegrini thought up the continetal theory before Alfred Wegener did

    Antonio Snider-Pellegrini thought up the continetal theory before Alfred Wegener did
    French Scientist. Antonio Snider-Pellegrini published his book, Creation and its Mysteries Unveiled (La Création et ses mystères dévoilés). He pointed out that all of the continents were once connected together during the Pennsylvanian Period. The reason why he thought this is that he found matching fossils on all of the continents.
  • Alfred Wegener first thinks up the idea

    Alfred Wegener first thinks up the idea
    Alfred Wegener cfinds a scientific paper that listed fossils of identical plants and animals found on opposite sides of the Atlantic. Alfred Wegener began to look for more cases of similar creatures separated by oceans. At that time people believed that bridges had once linked continents. However Alfred Wegener noticed the close fit between many countries such as Africa and South America and came to the conclusion that the countries at one point may have been joined together.
  • Alfred Wegener proposed the theory of the continental drift

    Alfred Wegener proposed the theory of the continental drift
    Alfred Wegener first publicly presented the theory of continental drift. Which he argued that the continents were once joined together as one land and have slowly drifted apart.
  • 'The Origin of Continents and Oceans' was published

    'The Origin of Continents and Oceans' was published
    The first edition of 'The Origin of Continents and Oceans' (Die Entstehung der Kontinente und Ozeane), a book outlining Wegener's theory, was published
  • Expanded edition of 'The Origin of Coninents and Oceans' Published

    Expanded edition of 'The Origin of Coninents and Oceans' Published
    An expanded edition of the book about Alfred Wegener's theory 'The Origin of Continents and Oceans' (Die Entstehung der Kontinente und Ozeane) was published.
  • Expanded edition of 'The Origin of Coninents and Oceans' Published

    Expanded edition of 'The Origin of Coninents and Oceans' Published
    Another expanded edition of the book about Alfred Wegener's theory 'The Origin of Continents and Oceans' (Die Entstehung der Kontinente und Ozeane) was published.
  • Expanded edition of 'The Origin of Coninents and Oceans' Published

    Expanded edition of 'The Origin of Coninents and Oceans' Published
    Another expanded edition of the book about Alfred Wegener's theory 'The Origin of Continents and Oceans' (Die Entstehung der Kontinente und Ozeane) was published.
  • Increase of exploration of theory

    Increase of exploration of theory
    For Alfred Wegener's theory many scientists started to believe it may be possible and started to explore more deeply into the earth's crust for more proof and details . The new science of palaeomagnetism started at Cambridge University by S. K. Runcorn and at The Imperial College , P.M.S. Blackett was soon producing data in favour of Wegener's theory.
  • Samples from India Proves Wegener's theory is correct

    Samples from India Proves Wegener's theory is correct
    By early 1953 samples taken from India showed that the country had previously been in the Southern hemisphere as predicted by Wegener.
  • Robert Sinclair Dietz was ldiscsussing ideas about continental drift,

    Robert Sinclair Dietz was discussing ideas about continental drift,
  • More people started believing the theory

    More people started believing the theory
    The theory had enough supporting data that minds were starting to change
  • Harry Hammond Hess helped Alfred Wegener with his theory

    Harry Hammond Hess helped Alfred Wegener with his theory
    Harry Hammond Hess, a professor of geology at Princeton University, was very influential plate-tectonics theory. He believed in many of the observations Wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the Earth.
  • Alfred Wegener was recognised as the founder of a major scientific revolution

    Alfred Wegener was recognised as the founder of a major scientific revolution
    Alfred Wegener was quickly recognized as the founding father of one of the major scientific revolutions of the 20th century and with the advent of the Global Positioning System (GPS), it became possible to measure continental drift directly.  
  • The royal sociery held a meeting for the theory

    The royal sociery held a meeting for the theory
    The United Kingdom Royal Society held a meeting on the subject of Alfred Wegener's plate tectonic theory.
  • Plate tectonic theory accepted and supported by most geologists

    Plate tectonic theory accepted and supported by most geologists
    By the late 1960s, plate tectonics was well supported and accepted by almost all geologists.
  • Fully support and believe Alfred Wegener's theory

    Fully support and believe Alfred Wegener's theory
    Now most people believe and realise Alfred Wegener's theory was correct. His information in continental drift is used in further research to find more information about the Earth's past.
