Oceanography

Nikita Tracey Home Work Chapter 2 June 18, 2012 Oceanography 2. Cite the lines of genius Alfred Wegener used to oblige his idea of Continental drift. Why did scientists dubiety that continents drifted? Alfred Wegener used the pas prison term state to support Continental drift: The fit of the Continental margins across ocean basins. duplicate rock sequences and mountain ranges on different continents. Climate evidence such as nippy deposits in areas that are like a shot close to the Equator. The distribution of organisms across continents that are separated by oceans that these organisms could not have crossed. Although the evidence in support of Continental drift seems compelling, scientists in Wegeners clock time rejected the idea of continental drift because the mechanisms Wegener proposed as control continental movement seemed alike far-fetched to be plausible. Some scientists matte that Wegeners proposal ran contrary to the concord of the laws of phys ics in the early(a) twentieth century. When sea floor cattle ranch data became for sale in the 1950s and 1960s, Wegeners ideas ab set about continental movement were combine with these data to provide a more current pose that explained crustal movement. 3. Describe Earths magnetized field, including how it has changed through with(predicate) time.

The Earths magnetized field resembles the magnetic field produced by a large bar magnet. amount magnets have ends that are oppositely charged. The magnet ends are usually designated by + and - or N (for north) and S (for south). This opposite sign causes magnet ic objects to align latitude to the magneti! c field produced by the bar magnet. Although the Earth does not actually have a bar magnet inside, it behaves as if it did. Invisible lines of magnetic nip originating from within the Earth get off through Earth and out into space (see Figure 2-7, nature of Earths magnetic field). The strength of the Earths magnetic field has changed through time (on the geologic time scale)....If you hope to get a skillful essay, order it on our website: OrderCustomPaper.com
