The Origin of Continents and Oceans

by Alfred Wegener

Book Overview

In 1915 Alfred Wegener''s seminal work describing the continental drift was first published in German. Wegener explained various phenomena of historical geology, geomorphy, paleontology, paleoclimatology, and similar areas in terms of continental drift. This edition includes new data to support his theories, helping to refute the opponents of his controversial views. 64 illustrations.

THE MAJOR EXPOSITION BY THE ORIGINATOR OF "CONTINENTAL DRIFT"

Alfred Wegener (1880-1930) was a German scientist, geophysicist, and meteorologist, most known for his theory of continental drift. He states in the Historical Introduction, that "The first concept of continental drift first came to me as far back as 1910, when considering the map of the world, under the direct impression produced by the congruence of the coastlines on either side of the Atlantic. At first I did not pay attention to the idea because I regarded it as improbable. In the fall of 1911 ... I undertook a cursory examination of relevant research in the fields of geology and paleontology, and this provided immediately such weighty corroboration in my mind." He writes, "Paleontologists ... have come again and again to the conclusion that the majority of those continents which are now separated by broad stretches of ocean must have had land bridges in prehistoric times and that across these bridges undisturbed interchange of terrestrial fauna and flora took place. The paleontologist deduces this from the occurrence of numerous identical species that are known to have lived in many different places, while it appears inconceivable that they should have originated simultaneously in these areas." He rejects the idea of "sunken continents" such as Atlantis and Lemuria: "Where the ocean basins are involved, it is not a question whether drift theory or the theory of sunken continents is to be preferred, because the latter idea just does not come into the picture." He states, "I must confess, however, that it is difficult to see how anyone can seriously assume today that the equatorial bulge could have kept its position unchanged, as though the earth were absolutely solid." He summarizes, "The forces which displace continents are the same as those which produce great fold-mountain ranges. Continental drift, faults and compressions, earthquakes, volcanicity, transgression cycles and polar wandering are undoubtedly connected on a grand scale. Their common intensification in certain periods of the earth's history shows this to be true."

It was good

It was very complex, with all the theories and information on continental drift.But, overall it was good.
