At the Plate Boundaries
The point where two plates collide. When two continental plates collide a mountain is formed. When two oceanic plates collide, a chain of volcanoes is formed. When an oceanic plate and a continental plate collide, it can result in earthquakes, volcanoes, or mountains.

What is a convergent plate boundary?
Random: Ms. Moore's favorite color.
What is green?
The earth has 4 layers. Magma comes from a viscous layer beneath the outer crust.

What is the mantle?
Random: Ms. Moore's home state.
What is Georgia?
These can become restless and erupt with only days to weeks warning. However, some of these have been restless for months or years before an eruption occurred, and sometimes a period of unrest doesn't produce an eruption at all.

What is a volcano?
The point where two tectonic plates separate or move apart. When two oceanic plates separate, a crack forms between and magma fills it in to form underwater mountains. When two continental plates separate, a rift valley forms, creating lakes and seas.

What is a divergent plate boundary?
This word describes the thickness of fluids such as lava.
(Hint: Lesson01.Session03)
What is viscosity?
A place where magma collects before it erupts.
What is a magma chamber?
This happens to magma when it erupts.
(Hint: Lesson01.Session05-06)
What is cooling and hardening?
A gas that is a component of magma, which leaves underground magma chambers, travels up through the soil, and is emitted into the air, affecting living things such as birds, small animals, and trees.

What is carbon dioxide?
The point where two plates slide past each other and form earthquakes.
(Hint: Lesson01.Session02)
What is a transform plate boundary?
This type of volcano is wide and shallow. It's lava has low viscosity.
(Hint: Lesson01.Session03)
What is a shield volcano?
A process that causes rocks to break down. Examples include wind and rain.
(Hint: Lesson01.Session04)
What is weathering?
This can cause rock to move from a mountain to the ocean floor.
(Hint: Lesson01.Session05-06)
What is weathering and erosion? or What is erosion?
These are different from earthquakes, but you probably can't feel the difference. Geologists can see the difference on a tracing made by an instrument called a seismograph, which detects the amount of ground shaking produced by these.

What are volcanic tremors?
The process that occurs when two plates converge, causing one of the plates to sink under the other.
(Hint: Lesson01.Session02)
What is subduction?
This type of volcano is steep with a crater top. It's lava has medium viscosity.
(Hint: Lesson01.Session03)
What is a cinder cone volcano?
A process that moves or transports pieces of rock to new areas.
(Hint: Lesson01.Session04)
What is erosion?
Rock weathered and broken down into very small pieces and moved into the ocean.
(Hint: Lesson01.Session05-06)
What is sand?
Sulfur dioxide is a gas common to volcanic eruptions. When this gas dissolves in water, it produces something that can corrode metal and cause severe burns.
(Hint: Dante's Peak Fact or Fiction Activity)
What is sulfuric acid? or What is acid?
Areas of the mantle that are unusually hot. The rock in these areas melts and rises as magma through the mantle. When it breaches the Earth's crust volcanoes are formed.
(Hint: Lesson01.Session02)
What is a hot spot?
This type of volcano is tall and steep. Its lava has high viscosity.
(Hint: Lesson01.Session03)
What is a stratovolcano?
(Hint: Lesson01.Session04)
What is deposition?
This happens to rock when it experiences lots of heat in the mantle.
(Hint: Lesson01.Session05-06)
What is melting?
Cascade Range in the United States Pacific Northwest is the location of the real eruption of this famous stratovolcano.
