What is the largest plate?
100

What is the mantle?
100
A volcano that is non-explosive and looks like a hill.
What is a shield volcano?
100
mafic lava runs faster than felsic lava due to the silica content.
What is the difference in velocity between Felsic and mafic lava?
100
Explosive volcanoes
What is the type of Volcano that has a lot of CO2 and H2O in it?
200
A boundary where two plates are moving away from each other.
What is a divergent boundary?
200
The earths crust.
What is the smallest layer?
200
A place that forms a circle of volcanoes around the Pacific plate
What is the ring of fire?
200
When it is under the lithosphere it is called magma but when it rises above surface it is now called lava.
What is the difference between magma and lava names?
200
It makes a volcano explode
What is the release of pressure do to a volcano?
300
One of the biggest divergent boundaries where new magma rises, hardens, and pushes old rock out of the way.
What is the mid-atlantic ridge?
300
A place that is made of solid iron
What is the earths core?
300
A volcano that sterotypes all volcanos in movies.
What is an Composite volcano?
300
The temperature 700 C and 1300 C.
What is the most common temperature for magma?
300
The lack of sulfur, Chlorine, H2O, and Fluorine gases.
What is in a non-explosive volcano that makes it not explode?

Oceanic crust is more dense when continental crust is less dense.
What is the difference between oceanic and continental crust?
400
A country made from many composite volcanoes.
What is japan?

What is geothermal heating.
What is the process of heating your home with magma under the ground?
400
Because when the water gets hot it turns into steam which can cause pressure.
What is the reason why water makes a volcano erupt?
500
Because when a plate gets pushed under another plate it gets refused and turns back into magma.
What is the reason why the number of tectonic plates stay the same?
500
Because all the dense materials like iron travels to the core?
What is the reason why the solid iron core is iron?
500
On composite explosive volcanoes.
What is the place where most shield volcanoes are found?
500
A type of magma that is the coolest and when it hardens it makes a Igneous rock.
What is Rhyolitic magma?
