theories and ideas presented thus, not generally accepted. In the 1960s, plate tectonics emerged that explained Earth’s features such as continents, oceans, volcanoes, earthquakes, valleys and mountains. This theory became widely accepted by virtually all Earth scientists.
A plate is a solid rock that is large and rigid while the Greek word tectonics means ‘to build’. Plate tectonics is the study of how the surface of the Earth is formed, how the separate pieces of it moves and the effects of this movement (Cambridge Dictionaries, 2014)
Understanding the dynamic planet upon which we live has been made and transformed significantly although the concept is fairly new.
According to plate tectonics, the Earth is in constant random motion. The Earth is

However, it was not until 1912 that a German scientist named Albert Wedgner proposed and developed the theory of continental drift. He later published his work in 1915 in his book “…………………..” His hypothesis proposed that the continents were once joined and has drifted apart overtime. This was due to the observation that most, if not all of the continents fits together like a puzzle. He believes that the continents were once a single protocontinent. This he referred to by the Greek word ‘Pangea’ which is translated in English to ‘all land’. He’s also of the view that about 300 million years ago in the Carboniferous period, the Pangea began to break and drift apart. Wedgner held strong on this theory because when he looked at the continents of South America and Africa, their edged joined together like a perfect puzzle. Major observations supported this theory. However, they observations could not have been proven. Wedgner ideas challenged scientists in other similar fields of study such as geophysics, paleotology, geology etc. Because of this, the theory was not widely accepted and received negative feedback from these
