Continental Drift It takes a lot of courage to stand up for something you believe in‚ especially when faced with intense amounts of scrutiny and rejection from colleagues and peers alike. But this is exactly what Alfred Wegener experienced when he advanced the unthinkable thoughts that all continents were once upon a time‚ all part of one massive supercontinent. He battled through the adversity‚ and continued to collect sources and ideas that backed his thinking. The purpose of this paper is

BACKGROUND Continental drift is a theory proposed by a scientist‚ Alfred Wegener in the twentieth century. The theory explained that all the continents was once joined as one‚ and through the course of millions of years‚ drifted apart from each other to form separate continents as we see it now. THEORY Before all the continents were separated‚ they existed as one supercontinent‚ Pangaea (Lovett‚ 2008)‚ surrounded by a super ocean‚ known as Panthalassa. Movement of continents can be compared to

The development of the theory of plate tectonics from Continental Drift to the present The theory of continental drift first came to be in 1915 when Alfred Wegener first proposed his belief that 300 billion years ago there was one single supercontinent‚ Pangaea. At the time‚ most did not believe it was true as he had no proof or idea of how the masses of land would move. However‚ new evidence was put forward over time that fit with Wegener’s beliefs. The first key piece of evidence is the shape

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

Continental drift is a theory stating that the Earth’s continents have been joined together and have moved away from each other at different times in the Earth’s history. The theory was first proposed by Alfred Wegener in 1912. Whilst his general idea of continental movement eventually became widely accepted‚ his explanation for the mechanism of the movement has been supplanted by the theory of plant tectonics. However there was a problem in accepting this idea originally because Wegener had no convincing

Continental similitude’s were can’t help being illustrated distant with the thought that the mainland’s had once been associated via arrive scaffolds. The earth was cooling‚ as per the theory‚ and in the methodology it was contracting‚ bringing on ocean levels

Fauna of Asia is all the animals living in Asia and its surrounding seas and islands. Since there is no natural biogeographic boundary in the west between Europe and Asia‚ the term "fauna of Asia" is somewhat elusive. Asia is the eastern part of the Palearctic ecozone (which in turn is part of the Holarctic)‚ and its South-Eastern part belongs to the Indomalaya ecozone (previously called the Oriental region). Asia shows a notable diversity of habitats‚ with significant variations in rainfall‚ altitude
