Essay about plate tectonic theory

" Evaluate how plate tectonics theory allows our comprehension of the circulation of seismic and volcanic events” (40 marks) The idea of dish tectonics was initially introduced simply by Alfred Wegener in 1912. He noticed the regions an could see they interlock such as a jig noticed puzzle, as an example the West Photography equipment Coastline suits snugly in to the South American coastline, he suggested that at 1 point in time there was clearly only one huge continent named " Pangea”. Later data was discovered that demonstrated this theory as the fossil continues to be of a prehistoric, the Mesosaurous was found along the coast of Brazil as well as along the coastline of Gabon, also fossilised pollen species and rock sediments were equally found along these coastlines. This further indicated that Wegener's theory was correct. Wegener's tips were demonstrated further proper and developed upon each of our understanding of tectonic activities. Marine floor distributing was found out showing that rock is being created and destroyed, this lead us to believe that plates and plate boundaries existed. The mid-Atlantic shape is a beneficial plate border where by the Eurasian and North American plates are going apart, this allows magma to increase creating new plate materials. This has came up with the island of Iceland which has rift valleys that are evidence thus support the plates happen to be moving separate. Carbon going out with has helped prove this theory as the crust nearer to the UK is significantly older than the crust along the mid-Atlantic shape. Paleomagnetism is where metal elements inside the crust happen to be aligned in opposing layers. Every couple 1000 years the earth's polarity flips, this means that each time the metal elements line up themselves in the opposite direction. In the case of positive plate border plate tectonic theory offers helped the understanding even as we can now determine that for constructive begleiter boundaries fente volcanoes are definitely more common right here, therefore indicating the nature of a potential eruption will not be as damaging as a...
