VOLCANO LITE

                                         Volcanoes can be catastrophic events, but everything has its light side. With volcanoes, even the light side can be truly amazing.From this we have learned about the volcanos and their eruptions and the death of the peoples occured during the years 1815, 1883, 1902, 1985, 1792, 1783, 1919, 1822, 1631, 1772, 1951, 1982, 1902, 1741, 1783, 1911, 1814, 1963, 1877, 1991, 1640, 1845, 1951 etc.And we studied about various types and forms of volcanos, we studied about VEI(Volcanic Explosivity Index), their plume Height, Classifications, how often they have been formed, and also their examples. The poisionus gases formed during the volcano eruptions(ie, Carbon Dioxide(co2):Odorless gas human breathe out. In high concentration,as suffocating as putting a pillow over your face.,Hydrogen Sulfide(H2S):Gas with the foul smell of rotten eggs. It can mix with water vapor to form sulfuric acid,then fall as acid rain to pollute lakes and streams and kill plant life and fish . In big or long-lasting volcanic eruptions,sulfuric acid can form a haze that gets into the upper atmosphere,bouncing the sun's rays away from Earth and causing worldwide cooling .,Sulfur Dioxide(SO2):Produce poisonous,corrosive fumes.This is based on specifics from a real eruption at Laki,Iceland,in 1783,which desposited 14 cubic Km of basaltic lava. scientists think Laki lowered worldwide temperatures by one degree Fahrenheit.Volcanoes are a fascinating, dangerous, powerful force on earth. They need to be understood and respected, because they are capable of monumental harm. They do what they want, when they want to. Each has its own timetables and its own sometimes grouchy, nasty, unpredictable nature.So we have learned about the volcanos and there classifications also.
