The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true. Alfred Wegener (1880-1930) Except for a few converts, and those like Cloos who couldn't accept the concept but was clearly fascinated by it, the international geological community's reaction to Wegener's theory was militantly hostile. American geologist Frank Taylor had published a similar theory in 1910, but most of his colleagues had simply ignored it. Wegener's more cogent and comprehensive work, however, was impossible to ignore and ignited a firestorm of rage and rancor. Moreover, most of the blistering attacks were aimed at Wegener himself, an outsider who seemed to be attacking the very foundations of geology. Because of this abuse,Wegener could not get a professorship at any German university. Fortunately, the University of Graz in Austria was more tolerant of controversy, and in 1924 it appointed him professor of meteorology and geophysics.
In 1926 Wegener was invited to an international symposium in New York called to discuss his theory. Though he found some supporters, many speakers were sarcastic to the point of insult. Wegener said little. He just sat smoking his pipe and listening. His attitude seems to have mirrored that of Galileo who, forced to recant Copernicus' theory that the Earth moves around the sun, is said to have murmured, "Nevertheless, it moves!"
Scientifically, of course, Wegener's case was not as good as Galileo's, which was based on mathematics. His major problem was finding a force or forces that could make the continents "plow around in the mantle," as one critic put it. Wegener tentatively suggested two candidates: centrifugal force caused by the rotation of the Earth, and tidal-type waves in the Earth itself generated by the gravitational pull of the sun and moon.
He realized these forces were inadequate. "It is probable the complete solution of the problem of the forces will be a long time coming," he predicted in his last (1929) revision. "The Newton of drift theory has not yet appeared."
Wegener noted, however, that one thing was certain:
The forces which displace continents are the same as those which produce great fold-mountain ranges. Continental drift, faults and compressions, earthquakes, volcanicity, [ocean] transgression cycles and [apparent] polar wandering are undoubtedly connected on a grand scale. Wegener's final revison cited supporting evidence from many fields, including testimonials from scientists who found his hypothesis resolved difficulties in their disciplines much better than the old theories. Climatology was one such discipline.
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Answer: Management is utilizing the concept of JOB ROTATION in training Li.
Explanation: Job rotation is the practical aspect used by some employers to enable their employees advance through a sequence throughout their employment.
Job rotation is an important aspect of jobs because it motivates employees to learn new job description and in turn make them interested in the job not getting bored doing one thing and eventually staying with a company for long.
It also allows workers that works long hours and manually to rest well and relieve stress.
Like Li for example, works for a manufacturer of collectible plates and figurines, this involves manual labour. Job rotation will enable her to learn new things and relieve stress.
A reaction in which the reactants have more energy than the products is always an Endothermic reaction.
<u>Explanation:</u>
The word "exothermic" means "turning out".In endothemic reaction, less amount of energy is sufficient to break the bonds that exist between the reactants when compared to the amount of energy that is formed when new bonds are created.
The chemical energy that is stored within a product is nothing but its potential energy that can later be released. An example of an endothermic reaction is the burning of wood. when you burn wood, you can see that it releases energy in the form of heat and this warms up the surrounding environment.
the Nuremberg War Crimes trials established the international legal precedent that individuals who violate human rights can be held responsible for their actions.
