5. made of alternating layers
What is a composite volcano?
This type of volcano is
steep-sided,
made of alternating layers
of lava and tephra,
and sometimes
erupts violently.

6. What is a composite volcano? Mount Shasta is an example
of this type of volcano.

What is a volcano?
A weak spot in the crust
where molten material
comes to the surface.

8. occurs when the volcano shows signs it may erupt
What is active?
This stage in the
life cycle of a volcano
occurs when the volcano
shows signs it may erupt
in the near future.

9. This forms volcanic mountains.
What is lava?
This forms volcanic mountains.

10. This forms when a caldera
What is a lake?
This forms when a caldera
fills with water.

11. A plate boundary, such as the Great Rift Valley in East Africa,
What is a spreading boundary?
A plate boundary, such as
the Great Rift Valley in
East Africa,
that forms new oceanic
crust as lava pours out of
cracks in the ocean floor.
