Volcano  Morphology    

Morphology  is  a  word  used  to  describe  the  shape  of  the  land.    Volcano  morphology  can  reveal  a  lot  about  magma   chemistry  (i.e.  silica  content),  volatile  content,  type  of  volcanic  eruption,  and  eruption  duration.    

Instructions:  Examine  the  morphology  of  each  volcano  below.  Identify  each  type  of  volcano  (shield  volcano,  cinder  cone,   composite  cone,  volcanic  dome,  or  caldera)  plus  the  magma  type  (mafic,  intermediate,  felsic)  and  volatile  content   (high,  low,  or  variable)  responsible  for  creating  each  volcano.    The  scale  bars  show  relative  (not  exact)  sizes.
