Document Summary

Redoubt volcano, kenai penninsula effusive- means to pour out and are not very dangerous- can go up to the ruptering volcanoexplosive- volvanoes that are dangerous and cannot be near it. effusive vs. explosive viscosity, temperature, volatile (h2o,co2) content. Eruptive viscosity and temperature- lower in temperatures are more silicate rocks lower viscosity- flows like waterhigh viscosity- flows very slow- more resistantvolitiles turn into a gass when they reach the surface. As they get depressurized, it has large bubbles andexits. (theres a build up)erruptive traps the volitile which is why there more dangerous erruptions due to the build upvolatiles are carbon diooxide and watereffusive vs. explosive. Eruptive hot temperature and low silate means lower viscositythis has a very large shield (like a roman shield)- are bery broad (5 - 10 km)these ones are small and sizeshield volcanoes. Basaltic lava flow this is fast moving (30 km/hour) and can cover everywhereshield volcanoes a"a" lava pahoehoe lava.
