• 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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/16.jpg)
• 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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/18.jpg)
• 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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/20.jpg)
• 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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/21.jpg)
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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/22.jpg)
• Gravity• Earthquakes• Expanding gases• inertia

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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/24.jpg)
• 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.

• Less dense• More dense• Cooler• More viscous
![Page 27: The ring of Fire is a long string of volcanoes located around the edge of _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/27.jpg)
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 _____________________.](https://reader036.fdocuments.net/reader036/viewer/2022062516/56649d705503460f94a52e4a/html5/thumbnails/28.jpg)
• 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.
