Layers of the Earth
Earth’s Layers
How are the earth’s layers similar to an egg?
Shell=crust
Egg white=mantle
Yolk=core
Make a model of Earth
Using paper, make a pie-shaped piece to resemble the Earth.
On the front, label the following:Inner coreOuter core
MantleCrust
Lithosphere
Inner core
Outer core
Mantle
asthenosphere
lithosphere
crust
Open up your segment of the Earth and…
1.Mark the layers.2.Label the state of matter of each layer.
3.What elements make up the core?4.Label the thickness of each layer.
5.Label the temperature of each layer using the numbers below.
6. Lightly color your model.

The next layer of the Earth after theinner core would be the……
What state of matter is the outer core?
What elements are in the outer core?
OUTER CORE
LIQUID
Iron and Nickel
Outer core
Liquid
2,250 km

Nickel and iron
Why do you think the inner core issolid and the outer core is liquid?
The core of our Earth is tremendously hot.It is believed to have a temperature of
7,000 degrees Celsius.Pressure keeps the inner core a solid,
but allows the outer core tobe a melted, liquid state.
Mantle
solid and plastic
2,900 km
4,500 F
The mantleis a layer that is kind of like
tar on a hot day. It flows, butvery, very slowly.
.
Asthenosphere
plastic
The asthenosphere is just below the lithosphere.
It is part of the mantle. The asthenosphere
is solid rock that flows slowly, like hot asphalt or
peanut butter.
The lithosphere includes the crust of the Earth and the upper mantle.. It is solid.
The outermost layer of our Earth iscalled the crust.
Lithosphere, which includes
the crustsolid
120 km
100 F
As the liquid iron and nickel in thecore circulate, it creates a magnetic
field.
Oceanic and Continental Crust
