Describe how alfred wegener developed the idea of a "supercontinent" and why many scientists rejected his theory

Alfred Wegener suggested the existence of a supercontinent called Pangea or Urkontinent in his work “The Origin of Continents and Oceans”. He postulated, based on the amazing fit of Africa and South America, similar rock formations and various fossil evidence that some 200 million years ago there was only one continent called Pangea. After Pangea broke other continents drifted, over millions of years, to the positions they have now. To say that the reaction to this was negative would be an understatement. The causes for the uproar of the scientific community of that time were the proposed speed of the continental movement, the fact that they viewed Wegener as an outsider because he was a meteorologist and not a geologist and the general resistance to a dramatic change in an established theory. But with the mounting evidence, in time, the theory could not be denied. Now with the GPS we can even measure directly how much the continents move.  

acts of terrorism occur globally. the united nations global counter-terrorism strategy was created in order to build adequate systems of support and solidarity with victims of terrorism. here´s a summary of the proposed key themes: the importance of giving victims a face and a voice; protecting their dignity; giving victims legal status and defending their legal rights; providing victims with medical, psycho-social and financial support; building solidarity with victims; improving media coverage of victims; and focusing on the link between victims and counter-terrorism efforts more generally.
