Earths Layers
Plate Boundaries
Volcanoes
Earthquakes
Convection Currents
100
The innermost layer of the Earth.
What is the inner core?
100
When two plates move away from each other,magma fills the gap and new land is formed.
What is a divergent plate boundary?
100
An opening or rupture in the Earth's crust.
What is a volcano?
100
A scale to determine the magnitude of a earthquake.
What is the Richter Scale?
100
The reason plates move.
What are convection currents?
200
This layer is the third layer and some would say it has the characteristics of jell-o.
What is the mantle?
200
This is where one plate subducts (moves under) the other.
What is a convergent plate boundary?
200
An opening where the lava flows.
What is the vent?
200
A sudden release of energy in the Earth's crust.
What causes an earthquake?
200
It is less dense.
What is the reason magma rises?
300
The land you live on.
What is the continental crust?
300
This is where two plates slide horizontally against each other.
What is a transform plate boundary?
300
A place where magma is stored.
What is the magma chamber?
300
Something that occurs after the earthquake.
What is aftershock?
300
In the mantle.
Where do convection currents ocurr.
400
This layer is the earth's outermost layer.
What is the crust?
400
A mountain range is formed after this happens.
What happens when a oceanic plate subducts under a continental plate?
400
The side of a volcano or mountain.
What is a flank?
400
It is located in California.
What is state is the San Andreas Fault located in?
400
Less dense.
What is the density of magma inside the Earth.
500
The layer outside the inner core.
What is the outer core?
500
A trench or undersea volcano forms after this.
What happens when two oceanic plates converge?
500
Magma that has reached Earth's surface.
What is lava?
500
A fault caused by a divergent plate boundary.
What is a normal fault?
500
When convection currents keep going around in a circle and repeating.
What is a cycle?
