Island Arc   -   A several volcanoes located in a ring often erupting at the same time.                                        

 

  Surtsey - newly formed island formed from cooled volcanic lava.

 

 Mountains /volcanoes- formation of land forms that are created when tectonic plates collide, separate, or slide past each other.

 

 Geyser / hot springs- ground water that sprouts when heated or ignited by seismic waves.
