Tell me about the Inner Core...
Composition? (Type of rock?)
Density?
Temperature?
Inner Core:
Composition: Made of solid iron and nickel
Density: This is the most dense layer!
Highest temperatures! Hot as the sun
Why is the inner core solid?
The inner core is solid because
of….
PRESSURE
On the the outer core...
State of matter? (Solid, liquid, or gas)
Composition? (Type of rock)
Outer Core
● Liquid (molten) Metal
● Iron and nickel
What about the mantle?
Size?
Composition?
Mantle
LARGEST layer
● The upper mantle is….
Composed of soft slow flowing material
(part of asthenosphere)
● The lower part of the mantle is…
Composed of hot, but solid material
Lastly, the crust...
Composition?
Two types?
Density?
Crust
● Least dense of all the layers
● Continental and Oceanic
● Made up of solid rock: mostly granite and
basalt
So what is the difference
between the asthenosphere and
the lithosphere?
Lithosphere
● Part of the crust and upper mantle
● Lithosphere is broken up into tectonic
plates
So what is below the lithosphere?
The Asthenosphere is below the
lithosphere!
The asthenosphere is located and it flows in
the earth’s upper mantle.
Rock is soft and weak...it is close to melting.
Good luck!
