Volcanoes: Constructive or Destructive? Maples 9/2/11

What is a volcano? Volcano- Areas of earth’s surface through which magma and volcanic gases pass Volcano comes from the Roman word Vulcan, which means “fire”

What Does Constructive Mean? Constructive Process is the building up of the Earth’s surface. How can a volcano be constructive?

What Does Destructive Mean? Destructive Process is the tearing down of the Earth’s surface. How can a volcano be destructive?

Ring of Fire The Ring of Fire is an area on the Earth where large numbers of volcanoes and earthquakes occur. Where in the United States do you see the most volcanoes?

Who Studies Volcanoes? A volcanologist is someone who studies volcanoes. How can their studying volcanoes help us?
