3. AB CD 1 2 34 Volcanic Environments Match up the volcano with it’s location E 5

4. A 1 2 34 Volcanic Environments Submarine volcano erupting under the ocean at the Mid Atlantic ridge, a tensional (divergent) plate margin.

5. B 1 2 34 Volcanic Environments Composite cone volcano forming part of an island arc at a compressional margin where two oceanic plates meet and one is subducted under the other.

6. C 1 2 34 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.

7. D 1 2 34 Volcanic Environments Shield volcano formed at a hotspot in the earth’s crust. Lava is basic and runny. Eruption is non-violent.

8. 1 2 34 Volcanic Environments Match up the volcano with it’s location E 5 Caldera formed by collapse of magma chamber. Crater Lake is an example. Super volcanoes are very large calderas.

9. Pacific Ring Of Fire

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

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

12. 3 Major types of Volcanoes Shield Cinder Composite Each differs in size, shape and composition

13. TEXT p. 506 Compare and contrast the different types of volcanoes Provide an example of each type http://vulcan.wr.usgs.gov/Outreach/AboutVolcanoe s/volcano_types_quick_reference.html http://vulcan.wr.usgs.gov/Outreach/AboutVolcanoe s/volcano_types_quick_reference.html
