Transcript Scale Model of Earth`s Layers

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 core
Outer core
Mantle
Crust
Lithosphere
crust
lithosphere
asthenosphere
Mantle
Outer core
Inner core
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.
12,000 F
9,000 F
4,500 F
6. Lightly color your model.
100 F

What is the center layer called?
INNER CORE
What state of matter is it?
SOLID
What is it made of?
IRON AND NICKEL
Inner core
Solid
Nickel and iron
1,200 km
12,000 F
The next layer of the Earth after the
inner core would be the……
OUTER CORE
What state of matter is the outer
core?
LIQUID
What elements are in the outer core?
Iron and Nickel
Outer core
Liquid
Nickel and iron
2,250 km
9,000 F
Why do you think the inner core is
solid 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 to
be a melted, liquid state.
Mantle
solid and plastic
2,900 km
4,500 F
The mantle
is a layer that is kind of like
tar on a hot day. It flows, but
very, 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 is
called the crust.
Lithosphere,
which includes
the crust
solid
120 km
100 F
As the liquid iron and nickel in the
core circulate, it creates a magnetic
field.
