The Circle Of Fire Essays - Lines Of Latitude, Plate Tectonics

The Circle of Fire The insider facts of the Circle of Fire lies some place profound into the Earths development about 4.5 - 5 billion years prior. The Circle of Fire is a ring of volcanic mountains that Borders the banks of North and South America, alongside Asia and Thialand. It moreover structures a semi-cirlce from the southern tip of South America to Australia. The Earth is about 4.5 - 5 billion Years old. While man's recorded history is just around 5000 years old.(Circle of fire page 3) The Earth is comprised of 3 unique layers 1-The Crust, the Crust is the extremely top layer of the earth that we live on, it consits of 7 diverse crustal plates. 2- The mantle which is the center layer, This is made of a fluid plastic sort of material called magma, This material is continually streaming which causes the crustal plates to shift.3-The Inner Core, this is the focal point of the Earth, Scientists aren't sure yet they accept that it is strong magma. About 80% of the universes Earthquakes happen in the Circle of Fire. (The Hover of Fire p. 13) They occur in a restricted belt of deficiencies that run corresponding with the equator from North and South America to Asia. In 1950 an Expidition from Scripps Institute of Oceanography while investigating the ocean bottom off the shoreline of California discoverd crack Zones.(Circle of Fire p 17) These break zones run corresponding with the equator from North and South America to Asia down to Thailand too. Regularly these crack zones are not profound but rather they run ten to twenty miles wide. What's more, incredibly the spat a practically equivalent separation of around 400 - 500 miles long. The Circle of Fire is a baffling spot. In spite of the fact that nobody knows how it was shaped , researchers accept they are close, They likewise accept that once they reveal its mysteries, they will have the option to answer a large number of the unsolved inquiries of the Earths Formation.
