Continental Drift Were the continents of this planet always situated the way they are today? Could there have been one supercontinent that over time broke off into the continents we know now? Merriam-Webster Dictionary defines Pangaea as a hypothetical land area believed to have once connected the landmasses of the southern hemisphere with those of the northern hemisphere (Definition of Pangaea). This theory‚ discovered by Alfred Wegener‚ was known as the drift theory. Wegener used the fit of the

Running head: Wegener and the Theory of Continental Drift Alfred Wegener (1880-1930) was a German scientist in the fields of meteorology‚ astronomy‚ and geology. He was one of the first scientists to theorize about the continental drift or continents in motion‚ which supports the belief that the Earth’s continents once were a single land mass. Wegener called this land mass‚ "Pangaea"‚ because the continents began to break up‚ and various parts drifted away from one another. According to Wegener

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

Plate tectonics (from the Late Latin tectonicus‚ from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motions of Earth’s lithosphere. The model builds on the concepts of continental drift‚ developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were developed in the late 1950s and early 1960s. The lithosphere is broken up into tectonic plates. On

Plate Tectonics Ever since the beginning on time‚ Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth‚ and possibly of what the Earth may become at a certain point in time‚ has a great influence on understanding all aspects of living things‚ either in the past‚ present‚ or future.

INTRODUCTION Plate tectonics The large scale motions of the earth’s lithosphere are describe by a scientific theory called plate tectonics which explains that Earth’s outer layer is made up of plates‚ which have moved throughout Earth’s history. The theory was developed during first decade of 20th century (by a famous advocate Alfred Wegener) on the older concept of continental drift and was accepted by many geoscientific communities. There are currently seven major and many minor plates are present

Did you know that one day in the past the continents were connected with each other? Continental drift states that the continents that we know today were once one large landmass called‚ Pangea. Many people argue with the theory about the continental drift‚ because no one yet has proven to the theory’s idea. Many people have been trying to find ways of how the continental drift could have happen‚ by researching objects from the past. This gave scientist or people another point of view about the continental
