Rationale
• The following benchmark was chosen because of the preciseness with which it matched the nature of our topic
• Our group developed this presentation to provide secondary teachers with excellent electronic resources from which to develop a comprehensive lesson on volcanoes
SC.D.1.4.2 - knows that the solid crust of Earth consists of slow-moving, separate plates that float on a denser, molten layer of Earth and that these plates interact with each other, changing the Earth’s surface in many ways (e.g., forming mountain ranges and rift valleys, causing earthquake and volcanic activity, and forming undersea mountains that can become ocean islands).
Connections
• Science – Scientists gain a greater understanding of the forces that shape our earth through their study of the causes and consequences of volcanic activity.
• Technology – The study of volcanoes has led not only to more accurate prediction of eruptions but also to the use of thermodynamics as an alternate energy source. Improved devices that measure seismic occurrences are also being used to discover new petroleum reserves.
More Connections
• Society – By understanding the nature of volcanoes, scientists are better able to predict possible eruptions, saving human life and property. They are also able to determine the effects these eruptions may have on future weather conditions and changes in climate.
Living with Volcanoes

Nature of Volcanoes
WHAT IS A VOLCANO?• Mountain/hill built around vent connected
to reservoir of molten rock under earth’s surface
LOCATIONS OF VOLCANOES Volcanoes of the United States
Ring of Fire
Principal Types of Volcanoes
• Cinder Cones• Composite
Volcanoes• Shield Volcanoes • Lava Domes
Types of volcanoes
Volcanic Hazards
• Pyroclastic Density Currents (pyroclastic flows and surges)
• Lahars
• Structural Collapse: Debris flow-Avalanches
• Dome Collapse and the formation of pyroclastic flows and surges
• Lava flows• Tephra fall and
ballistic projectiles• Volcanic gas• Tsunamis• Volcanic LightningUCSB Geological Sciences - Hazards
Monitoring Volcanoes
• to obtain additional scientific knowledge on volcanoes
• help predict eruptions in an attempt minimize risk to population
