Volcanic Environments
Composite (stratovolcano) volcano found at a compressional margin where an oceanic plate is subducted beneath a continental plate. Lava is acidic and viscous.

Caldera formed by collapse of magma chamber. Crater Lake is an example.
Super volcanoes are very large calderas.

Anatomy of a Volcano Crater- top of volcano bowl shapeVent – opening Conduit – tube like structure connecting Magma chamber to ventCalderas- Very large depressions, forms when magma chamber empties, collapse and usually fills with water
Summit- side of volcano that collapses into empty chamber

Types of Volcanoes
Appearance of a volcano depends on
1.Type of material that forms the volcano
2.Type of eruptions that occur

3 Major types of Volcanoes
• Shield• Cinder• Composite
Each differs in size, shape and composition
