Layers of The Earth
Crustal Plates and Boundaries
Earthquakes
Volcanoes
100
This is the only liquid layer.
What is the outer core?
100
This type of boundary occurs when two plates push toward each other.
What is a convergent boundary?
100
Earthquakes are caused when Rock under ground suddenly breaks along a fault
Why do Earthquakes Happen
100
by landslides from the top of the volcano
how do volcanos cause tsunamis
200
This consists of two layers.
What is the Mantle?
200
This type of crust underlies continents.
What is continental crust?
200
These are the waves of energy caused by the sudden breaking of Rock within the Earths oran Explosion
What are Seismie Waves
200
magma
What is in the bottom of the volcano inside
300
These two layers are both made of Iron and Nickel.
What are the inner and outer core?
300
this type of crust is usually younger than continental crust.
What is oceanic crust?
300
This is a place where two tectonic plates meet
What is a fault line
300
lava
What is magma when it is shot out of the center of the volcano
400
This layer consists of the crust and upper-most solid Mantle.
What is the Lithosphere?
400
This type of boundary occurs when two plates push away or apart from each other.
What is a divergent boundary?
400
When Earthquakes occur sometimes they are followed by many smaller Earthquakes. These smaller Earthquakes are called:
What is and after shock?
400
no certain amount of times usually every couple years
how long does it take for a volcano to erupt
500
These are the six layers of the Earth.
What are the Mantle, Lithosphere, Asthenosphere, Outer Core, Inner core, and Crust?
500
Continental crust is about how many miles thick?
What is 20 to 40 miles?
500
Where a denser plates shifts below its neighboring plates Energy is Transferred and Displaced water form a Wave
