While German meteorologist Alfred Wegener first proposed his groundbreaking idea of continental displacement, later referred to as continental go with the flow, in 1912, his geologist friends rejected his concept as the box of geology on the flip of the century used to be established in 18th- and 19th-century observations concerning the nature of the earth and the planet's improvement. Wegener's thought of continental go with the flow proposed that the large landmasses slowly moved at the earth's floor over thousands of years. His notion defined numerous observations made concerning the earth, from how the continents shaped, to what explanations earthquakes, to how the earth's floor maintains to alter. An itinerant explorer, Wegener traveled all over the world, and he died whereas on a polar project in Greenland. It wasn't until eventually a long time after his dying that the continental go with the flow idea 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.

Example text

Ancient Continents Wegener wrote that in the Paleozoic era, more than 250 million years ago, all of the Earth’s crust that reached above sea level was gathered into a single huge continent. ” It occupied about half of the planet’s surface area and was surrounded by a single shallow ocean, Panthalassa (“all-sea”). 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.

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.

If he could have stood as we did, under the flickering northern lights, with an overwhelming feeling of insignificance at the sight of this phenomenon of nature, . . he would never have said such a thing. Above us the shining curtain unfolded in mysterious movements, a powerful symphony of light played in deepest, most solemn silence over our heads, as if mocking our efforts: Come up and investigate me! Tell me what I am! Popular Teacher and Writer Shortly after his return to Germany, Wegener began work on a textbook, Thermodynamik der Atmosphäre (Thermodynamics of the Atmosphere).
