3. Why do volcanoes erupt?
Hot, melted rock (magma) deep within the earth becomes lighter as it heats up. Because it is lighter than solid rock it rises until it pushes to the surface of the earth. A volcanic eruption occurs!

B) Near the edges of the earth’s plates.
C) Subduction and rift zones.
D) All of the above.

6. Why do volcanoes grow? A) Repeated eruptions
B) There are various types of volcanoes and each forms differently
C) Volcanoes were formed when the earth was formed and haven’t changed much since then.
D) Both A and B

7. What are the 3 main shapes of volcanoes?
A) Dome, Funnel, and crater
B) Shield, Cinder, and Composite
C) Volcanic, Tephra, and Slope
D) Hydrosphere, Cryosphere, and Lithosphere

8. A shield volcano is formed when
Great masses of lava slowly ooze out from an opening in the earth’s crust, forming a broad, gentle slope.*
Lava, huge rocks, cinders and ash explode high into the air forming a steep cone up to 35 degrees.
Formed by quiet and explosive eruptions.
Concave formation in the earth’s crust.

9. A cinder cone is formed when
Great masses of lava slowly ooze out from an opening in the earth’s crust, forming a broad, gentle slope.
Lava, huge rocks, cinders and ash explode high into the air forming a steep cone up to 35 degrees.*
Formed by quiet and explosive eruptions.
Concave formation in the earth’s crust.

10. A composite cone forms when
