Areas of Volcanism
Sub-ducting Boundaries• Plate Sub-ducts below surface into mantle
•
Oceanic-Oceanic• Volcanoes form near boundary
•
Mid Ocean Ridges• Eruptions occur where plates are diverging
•

Areas of Volcanism
– Hot Spots
• Hot Spots remain stationary while plates move above
•

Types of Volcanoes
– Shield Cone• Has a low rounded profile
• Gentle slopes of 2-10 degrees
•
– Composite Volcano (Strato Volcano)• Both pyroclastic layers and lava flows
• Steep sided near summit with decreasing slope
•

Types of Volcanoes
• Cinder Cone– Pyroclastic Material (Fragmented material that has been
explosively ejected)
– Ash and debris accumulates around the vent
– Small steep sided cones

Types of Lava
• Mafic» Silica Poor (45-52%)
• Intermediate» Silica Composition (53-65%)
• Felsic» Contains more than 65% Silica
