Conclusion

     Today there are between 500 and 600 active volcanoes on earth.  Many of these volcanoes circle the shores of the Pacific Ocean.  This is called the Ring of Fire.
      About 30 volcanoes erupt each year.
      Where will the next big eruption take place?
     Volcanologists look for clues that will help them predict when a volcano will erupt.  It is dangerous work but many lives can be saved from what volcanologists discover.
     Thank you for all the work that you did.  The more we learn,   the better our predictions about future eruptions will be.
