Volcanoes
 

  Volcanoes are part of the ever-changing force that we call Plate Tectonics. Volcanoes are evidence that is used in proving that there is movement under our feet in a world that we always think is solid and free of movement. In this exercise, you will be using the Internet to discover information about volcanoes and the volcanic setting across the world. Follow all procedures, read all the directions, and answer all questions.
