Alfred Wegener: Creator of the Continental Drift Theory by Lisa Yount

By Lisa Yount

While German meteorologist Alfred Wegener first proposed his groundbreaking thought of continental displacement, later referred to as continental glide, in 1912, his geologist friends rejected his conception as the box of geology on the flip of the century was once dependent in 18th- and 19th-century observations concerning the nature of the earth and the planet's improvement. Wegener's idea of continental go with the flow proposed that the big landmasses slowly moved at the earth's floor over hundreds of thousands of years. His suggestion defined numerous observations made concerning the earth, from how the continents shaped, to what reasons earthquakes, to how the earth's floor keeps to alter. An itinerant explorer, Wegener traveled worldwide, and he died whereas on a polar challenge in Greenland. It wasn't until eventually a long time after his dying that the continental flow concept proved fruitful to different scientists within the twentieth century. In "Alfred Wegener", find out how this bold adventurer pieced jointly a concept that later revolutionized the Earth sciences.

Pangaea broke up and its fragments slowly separated from each other during the Mesozoic era, Wegener claimed. In the Jurassic period, it split into three smaller protocontinents, two northern ones and a southern one. One of the northern continents was more or less the same as present-day Asia; the other consisted of what is now North America, Greenland, and Europe. S. Geological Survey, published a theory of continental movement somewhat like Alfred Wegener’s in 1910, two years before Wegener presented his first talk on continental drift.

According to a colleague, Professor Benndorf, Wegener had mixed feelings about his service: he was loyal to his country, but he felt that war was pointless. Nonetheless, he saw enough action to be wounded twice later in 1914, first in the arm and later, two weeks after he had returned to the battlefront, in the neck. Although he continued to serve in the military meteorological service, he was relieved of active duty for the remainder of the war. During the time he spent at home recovering from his wounds, he turned once more to the theory he had been forced to set aside and began gathering the additional evidence he would need to flesh it out into a book.

British scientist Robert Hooke (1635–1703) created an anemometer, a device for measuring wind speed, in 1667. Gabriel Fahrenheit (1686– 1736), a German physicist, invented the mercury thermometer and created a temperature scale to go with it in 1714. (A second scale, the centigrade or Celsius scale, was devised by Swedish astronomer Anders Celsius (1701–44) in 1742. D. from the University of Berlin on November 24, 1904, magna cum laude, for this work. He went on to write an article on the history of the venerable tables as well.
