The ring of Fire is a long string of volcanoes located around the edge of _____________________.

Page 2: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• The Pacific Ocean• The Atlantic Ocean• Africa• Australia

Page 3: The ring of Fire is a long string of volcanoes located around the edge of _____________________

Where do most volcanoes occur?

Page 4: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• In the tropics• In the middle of tectonic plates• Along the edges of tectonic plates• Along earthquake faults

Page 5: The ring of Fire is a long string of volcanoes located around the edge of _____________________

Which of these geologic formations would probably be found along the boundary where two tectonic plates meet?

Page 6: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• A plateau• A natural bridge• A volcano• An ocean

Page 7: The ring of Fire is a long string of volcanoes located around the edge of _____________________

Where are most volcanoes located?

Page 8: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• In Africa• In the middle of tectonic plates• Along the edges of tectonic plates• In the middle of continents

Page 9: The ring of Fire is a long string of volcanoes located around the edge of _____________________

Along the west coast of South America, one plate is diving beneath another plate, creating volcanic mountains. This process is known as_____________________

Page 10: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Subduction• Faulting• Isostasy • sedimentation

Page 11: The ring of Fire is a long string of volcanoes located around the edge of _____________________

New islands are continuously being formed in the Hawaiian Island chain because___________________.

Page 12: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• A rift valley is opening up in the Pacific Ocean• The pacific plate is moving over a hot spot• The islands are moving over a plate boundary• The islands are sinking into the Earth’s crust

What are the two main gasses released by volcanoes?

Page 14: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Hydrogen and helium• Argon and neon• Methane and propane• Water vapor and carbon dioxide

What property of liquid rock enables it to rise up through cracks in the earth’s crust?

Page 16: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Color: Liquid rock is lighter in color than solid rock

• Texture: Liquid rock is smoother than solid rock

• Density: Liquid rock is less dense than solid rock

• Temperature: Liquid rock is hotter than solid rock

Why would it be more likely that you would see lava as opposed to magma?

Page 18: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Lava is the term for magma after it has flowed out of the ground

• Magma is much hotter than lava so you can not see it as well.

• Magma can only be found and seen at the bottom of the ocean.

• Magma is much darker in color than lava so it is harder to see.

What do minor earthquakes in the vicinity of a volcano indicate?

Page 20: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• There is a fault inside the volcano• The tectonic plates are moving• Magma inside the volcano is getting hotter• Magma inside the volcano is rising

Page 21: The ring of Fire is a long string of volcanoes located around the edge of _____________________

What causes molten rock to explode out of a volcano?

Page 22: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Gravity• Earthquakes• Expanding gases• inertia

Page 23: The ring of Fire is a long string of volcanoes located around the edge of _____________________

How is a volcano like a water faucet?

Page 24: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Both a volcano and a water faucet can be turned on and off at will

• Both a volcano and a water faucet work because of a difference in temperature

• Both a volcano and a water faucet have chambers directly below them

• Both a volcano and a water faucet are locations where a fluid can flow out of an otherwise closed system.

Magma inside the earth may start to rise because it is ________________than the surrounding rock.

Page 26: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• Less dense• More dense• Cooler• More viscous

Why do most volcanoes form near the boundaries of tectonic plates?

Page 28: The ring of Fire is a long string of volcanoes located around the edge of _____________________

• There are week spots at the boundaries so magma can erupt there

• Magma can rise up between the plates when the plates move apart at these boundaries

• Magma is stronger near the boundaries of tectonic plates so this where volcanoes often form.

• There is an abundance of magma at the boundaries of tectonic plates so eruptions often occur here.
