QUESTION 8 Using Chapter 5 of your textbook and the details provided above, identify the volcano type for each example. Also provide one location example for that
volcano type. (8 pts)
C. Volcano A: Silica and gas content are both high (viscosity is greatest). A. Composite (Stratovolcano) / Mount Fujiyama, Japan
This silica rich magma is cooler and is so viscous that it hardly flows at
all
B. Shield volcano / Kilauea, Hawaii
A Volcano B: Silica, gas content, and eruption temperature are all
c. Lavan Dome / Mount St. Helens, U. S.A.
moderate (viscosity is moderate - allowing for both periods of D. Cindei Cone/SP Crater, U. S.A.
explosiveness as well as readily flowing magma)
B. v Volcano C: Silica and gas content are both relatively low (viscosity is
low, allowing for magma to easily flow far). This is the least explosive
of the volcano types,
D. Volcano D: Silica and gas content are moderately high at eruption
onset, then wain as the eruption progresses (this yields a field of
pyroclastics surrounding the volcano crater, and a lava field flowing
away from the crater)
