Essay about continetal drift theory 1841 words 8 pages continental drift, the theory that continents move slowly about the earth's surface, changing their positions relative to one another and to the poles of the earth. Basically, 'continental drift' is an idea (or a hypothesis) without a really workable mechanism while 'plate tectonics' is a fully developed and empirically supported (by evidence and observation) explanation (a theory) which explains how 'continental drift' occurs.
Once plate tectonics was proposed and accepted, and enough evidence for that theory supported it beyond a reasonable doubt, the fossil evidence made far better sense the movement of continents has had a profound influence on how land animals evolved. One of the most important contributions to the development of plate tectonic theory was alfred wegener's 1915 publication of 'the origin of continents and oceans' which outlined his theory of continental drift wegener supported his argument with five lines of evidence. The theory of continental drift is the idea that about one most important contributions to development plate tectonic was alfred wegener supported his argument with five lines evidence solutions. Key words: continental drift, scientific theory, plate tectonics in 1915, a scientist by the name of alfred wegener proposed the continental drift theory the idea that the continents are continuously moving either towards or away from each other essay on the evidence that supports the theory of continental drift and plate tectonics.
Plate tectonics is the grand, unifying theory of earth sciences, combining the concepts of continental drift and sea-floor spreading into one holistic theory that explains many of the major structural features of the earth's surface.

Plate tectonic is newer form of continental drift with more evidence and an proposed mechanism for the movement of the continents continental drift was rejected at the time it was proposed despite substantial evidence to support the theory. The first evidence supporting the theory of continental drift was _____ the first piece of the evidence explains why parts of continents, such as the west coast of africa and the east coast of south america, seem to fit together like two jigsaw puzzle pieces.
Development of tectonic theory precursors by the 1960s, although evidence supporting continental drift had strengthened substantially, thus, while wegener did not manage to persuade the scientific world of continental drift, the successor theory, plate tectonics,. We will write a custom essay sample on chapter 4 plate tectonics specifically for you for only $1638 $139/page how does the mesosaurus fossil evidence support the continental drift theory the mesosaurus fossil evidence supports the continental drift theory because its unlikely that the mesosaurus could swim between continents 18. The theory of plate tectonics was developed from the theories of continental drift and sea-floor spreading and states that the earth’s surface is divided into several large plates, which are constantly in motion. Therefore continental break up is a strong piece of evidence to support the theory of continental drift geology of rock formations and mountain ranges on separate continents were also suggested by wenger as evidence of continental drift. Wegener proposed the continental drift theory in the early 20th century he was able to provide scientific evidences for such, but sadly he was unable to explain the mechanism or processes behind the movement of continents.
Using the online resources at the earthquakes living lab, students examine information and gather evidence supporting the theory working in pairs, students think like engineers and connect what they understand about the theory of plate tectonics to the design of structures for earthquake-resistance. This essay on the evidence that supports the theory of continental drift and plate tectonics by pardoner contributor current of the “gulf stream’, which surrounds england’s shores, and therefore reduce the annual temperature which would then become significantly colder. Continental drift is the theory that our the earth's continents rest upon plates that float across the molten mantle of the earth german scientist alfred wegner, was one of the first to state a hypothesis that such a thing can occur, but he did not have sufficient evidence to support his claims. Continental drift is the movement of the earth's continents relative to each other, thus appearing to drift across the ocean bed the speculation that continents might have 'drifted' was first put forward by abraham ortelius in 1596 the concept was independently and more fully developed by alfred wegener in 1912, but his theory was rejected by some for lack of a mechanism, which was.
