It was only early scientists like Galileo who needed to fear the reaction to their radical views. Neither of these beliefs is true. Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century.

Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart.

The jigsaw fit that the continents make with each other can be seen looking at the map of soil types below derived from University of Idaho. South America can be dragged and rotated rotating is tricky by touch so you can try to see how well it joins with Africa.

Wegener and his Critics Since his ideas challenged scientists in geology, geophysics, zoogeography and paleontology, it demonstrates the reactions of different communities of scientists. These reactions eventually shut down serious discussion of the concept.

The geologist Barry Willis summed it up best: Why the extreme reaction? Wegener did not even present Continental Drift as a proven theory.

He knew he would need more support to convince others. His immediate goal was to have the concept openly discussed. These modest goals did not spare him. His work crossed disciplines.

The authorities in the various disciplines attacked him as an amateur that did not fully grasp their own subject.

More importantly however, was that even the possibility of Continental Drift was a huge threat to the authorities in each of the disciplines.

Radical viewpoints threaten the authorities in a discipline. Authorities are expert in the current view of their discipline. A radical view could even force experts to start over again. Thomas Chamberlain, suggested just that: Building the Case In spite of all the criticism, Wegener was able to keep Continental Drift part of the discussion until his death.

He knew that any argument based simply on the jigsaw fit of the continents could easily be explained away. To strengthen his case he drew from the fields of geology, geography, biology and paleontology.

Wegener questioned why coal deposits, commonly associated with tropical climates, would be found near the North Pole and why the plains of Africa would show evidence of glaciation. Wegener also presented examples where fossils of exactly the same prehistoric species were distributed where you would expect them to be if there had been Continental Drift e.

The graphic below shows the striking distribution of fossils on the different continents. Wegener used an Alexander duToit graphic to demonstrate the uncanny match of geology between eastern South America and western Africa.

To explain the unusual distribution of fossils in the Southern Hemisphere some scientists proposed there may once have been a network of land bridges between the different continents. To explain the existence of fossils of temperate species being found in arctic regions, the existence of warm water currents was proposed.

Modern scientists would look at these explanations as even less credible than those proposed by Wegener, but they did help to preserve the steady state theory. New theories often have rough edges. Wegener did not have an explanation for how continental drift could have occurred. He proposed two different mechanisms for this drift.

These explanations could easily be proven inadequate. They opened Wegener to ridicule because they were orders of magnitude too weak. Wegener really did not believe that he had the explanation for the mechanism, but that this should not stop discussion of a hypothesis.

A major conference was held by the American Association of Petroleum Geologists in that was critical of the theory.(used relatively in restrictive clauses having that as the antecedent): Damaged goods constituted part of that which was sold at the auction.

Flood geology (also creation geology or diluvial geology) is the attempt to interpret and reconcile geological features of the Earth in accordance with a literal belief in the global flood described in Genesis 6– the early 19th century, diluvial geologists hypothesized that specific surface features were evidence of a worldwide flood which had followed earlier geological eras; after.

It is the theory that the earth’s continents are constantly in motion and at one time they all collided together to form one massive continent about million years ago! Pangaea (meaning “all lands”) began to break up and drift apart.

The plate moving deeper into the earth melts due to the. The development of the theory of plate tectonics from Continental Drift to the present The theory of continental drift first came to be in when Alfred Wegener first proposed his belief that 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. Poetry. Adams, Kate, Bright Boat, 69; Adamshick, Carl, Everything That Happens Can Be Called Aging, 91; Adamshick, Carl, Tender, 91; Adamson, Christopher, J.

The Evidence In Support Of The Theory Of Continental Drift Essay Sample. The continental drift theory was first proposed by a German called Alfred Wenger in He suggested that the earth’s continents were once joined together, but gradually moved apart over millions of years.

This once ‘supercontinent’ was known as Pangea – which translates to ‘’All Earth’’.
