Intro Objective: 19 November 2012 Compare and contrast the three types of volcanoes. Pick up worksheet (tape into notebook) Weekly Worksheet #13: Why do you think different eruption types make differently shaped volcanoes?
Types of Volcanoes
Shield Volcano Built from layers of runny lava from multiple quiet eruptions Shallow, broad slope creating a flat, wide volcano Example – Name: Mauna Kea – Location: Hawaii Types of Volcanoes Flipchart pg. 2
Mauna Kea, Hawaii
Hualalai, Hawaii
Kilauea, Hawaii
Mt. Okmok, Alaska
Effects of Volcanoes Composite Volcano Alternates between quiet and violent eruptions Creates alternating layers of lava and ash debris (tephra) Broad bases and steep sides (looks like regular mtn.) Example – Name: Mt. St. Helens – Location: Washington, USA Types of Volcanoes Pg. 3
Mt. Fuji, Japan
Mt. St. Helens
Mayon, Philippines
Popocatépetl, Mexico
Mt. Kazbek, Georgia (the country)
Pinatubo, Philippines
Lassen Peak, California
Krakatoa, Indonesia
Types of Volcanoes Cinder Cone Volcano Made mostly of pyroclastic material from moderately explosive eruptions. Steep slopes but small in size Tephra, cinders, ash, pyroclastic rocks Example – Name: Paricutín – Location: Mexico Types of Volcanoes Flipchart Pg. 4
Sunset Crater, Arizona
Holocene, Utah
Parícutin, Mexico
Effects of Volcanoes Summary: – Describe a shield volcano. – Describe a composite volcano. – Describe a cinder cone volcano.
