3 the Earth’s surface that
What is lava? Molten rock above the Earth’s surface that erupts from volcanoes. Row 1, Col 1

4 Sticky, thick lavas are rich in this.
What is silica? Sticky, thick lavas are rich in this. 1,2

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. 1,3

6 What is a composite volcano? Mount Shasta is an example
of this type of volcano. 1,4

7 A weak spot in the crust where molten material comes to the surface.
What is a volcano? A weak spot in the crust where molten material comes to the surface. 2,1

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. 2,2

9 This forms volcanic mountains.
What is lava? This forms volcanic mountains. 2,3

10 This forms when a caldera
What is a lake? This forms when a caldera fills with water. 2,4

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. 3,1

12 What is an explosive eruption? and water vapors form this.
Magmas rich in silica and water vapors form this. 3,2

13 This forms as a result of a collapse of a volcano’s peak.
What is a caldera? This forms as a result of a collapse of a volcano’s peak. 3,3

14 When these move, California’s geological features change.
What are tectonic plates? When these move, California’s geological features change. 3,4

15 What is the Pacific Ring of Fire? an example of where many
Close to home, this is an example of where many colliding boundaries form many volcanoes. 4,1

16 Lava flows, pyroclastic flows, mud slides, and clouds of
What are the dangers people face during volcanic eruptions? Lava flows, pyroclastic flows, mud slides, and clouds of ash and poisonous gas are examples of these. 4,2

17 A large body of cooled magma beneath the Earth’s surface.
What is a batholith? A large body of cooled magma beneath the Earth’s surface. 4,3

18 along plate boundaries.
What are faults? These are formed along plate boundaries. 4,4

19 What is in the middle of a plate? Like the Hawaiian Islands,
this is where hot spot volcanoes form. 5,1

20 surface because of this.
What is less dense? Magma rises to the surface because of this. 5,2

21 cuts across rock layers.
What is a dike? Hardened magma that cuts across rock layers. 5,3

22 Who are volcanologists? These scientists analyze
lava samples to help understand eruptions. 5,4
