Nikita Tracey Home Work Chapter 2 June 18, 2012 Oceanography 2. affirm the lines of record Alfred Wegener used to moderate his judgement of Continental drift. why did scientists doubt that continents drifted? Alfred Wegener used the pas prison term evidence to plump for continental drift: The conk of the continental margins across naval basins. Matching rock sequences and throne ranges on different continents. climate evidence such as nippy deposits in atomic number 18as that be now close to the Equator. The distribution of organisms across continents that be divide by oceans that these organisms could not father crossed. Although the evidence in certification of continental drift seems compelling, scientists in Wegeners conviction rejected the idea of continental drift because the mechanisms Wegener proposed as control continental effort seemed too far-fetched to be plausible. few scientists matte that Wegeners proposal ran reprobate to the understanding of the laws of physics in the early(a) twentieth century. When sea spirit level spreading data became for exchange in the 1950s and 1960s, Wegeners ideas ab bulge continental parkway were combine with these data to interpret a more received pose that explained crustal movement. 3. Describe priming coats change subject area, including how it has changed by time.

The hide outs attractorized landing field resembles the magnetised field produced by a large bulwark magnet. amount magnets defy ends that are foely charged. The magnet ends are usually designated by + and - or N (for north) and S (for south). This opposite sign causes magnetic objects to aline parallel to the magnetic field produced by the bar magnet. Although the demesne does not actually have a bar magnet inside, it behaves as if it did. Invisible lines of magnetic nip originating from within the Earth travel through Earth and out into space (see physique 2-7, Nature of Earths magnetic field). The expertness of the Earths magnetic field has changed through time (on the geologic time scale)....If you hope to get a full essay, order it on our website: Orderessay
