1. Station #9: At this station you will:
Describe characteristics of three volcano types
Write an example of each volcano type

2. Types of Volcanoes Cinder Cone Volcanoes: Typically occur in clusters
Made from pyroclastic material produced from moderately explosive eruptions.
Typically occur in clusters
Small
Erupt for a short time
Steep slopes
Paricutin erupted for only nine years

3. Types of Volcanoes Shield Volcanoes: Runny lava
Shield volcanoes are built of layers of lava from non-explosive eruptions.
Runny lava
Spreads over a wide area
Gently sloping sides
Mauna Kea in Hawaii is the tallest mountain on Earth

4. Types of Volcanoes Composite Volcanoes:
Form from explosive eruptions of pyroclastic material followed by quieter lava flows.
Referred to as “Stratovolcanoes”
Most common type of volcano
Alternating layers of pyroclastic material and lava
Broad bases and sides
Steeper towards the top
There are several stratovolcanoes along the western portion of the U.S. including Mount Hood pictured above.
