1. How do we know what
the inside of the Earth
is made of?
2. What are the three
basic layers of the
Earth.
3. What layer do we live
on?
4. What part makes up the
bulk of the Earth’s
mass?
When it all began…
• 4.5 billion years ago,
the Earth was in a fluid
state.
• As the Earth began to
cool, the materials
began to separate
because of their
densities.
What do you think happened to the more dense materials during the separation?
What about the less dense materials?
When it all began…
• This separation of
materials created the
layers we know exist
within the Earth today!
Stop and Jot
Why does the Earth have layers?
When it all began…
• Scientists have found
that the best way to
classify these layers is
in two ways – the
chemical composition
and the physical
properties.
How might we describe the chemical composition?
What would be some physical properties?
Chemical or Physical?
The
thickness of
a layer.
Physical
Chemical or Physical?
The
temperature
of a layer.
Physical
Chemical or Physical?
The
elements the
layer is made
of.
Chemical
Chemical or Physical?
The state of
matter of the
layer.

Chemical Composition
MANTLE
• When classifying the
layers by their
chemical composition,
there are three distinct
layers.
• The crust, the mantle,
and the core.
CORE
CRUST

Crust
CRUST
• The layer we live on.
• Found on the outside of
the Earth.
• Made up of lighter
elements.
• Oxygen
• Silicon
• Aluminum
• Calcium

CRUST
Mantle
MANTLE
• Found in the middle of the
Earth.
• Made up of elements with
more density than the
crust.
• Oxygen
• Silicon
• Magnesium
• Iron

CRUST

Core
CORE
• Found in the very center of
the Earth.
• Made up of the most dense
elements.
• Iron
• Nickel

Example
• We can think of these
layers like a hard
boiled egg or an apple.
What do you think would be considered the crust? What do you think would be
considered the mantle? What do you think would be considered the core?
Physical Properties
• When classifying the layers
by their physical
properties, there are five
distinct layers.
• The lithosphere, the
asthenosphere, the mantle,
the outer core, and the
inner core.

The Lithosphere
LITHOSPHERE
LITHOSPHERE
• Includes the crust and the
uppermost portion of the
mantle.
• Thickness of the Crust:
5-70 km
• State of Matter:
Solid
Follow along on pages 273-276
The Asthenosphere
LITHOSPHERE
ASTHENOSPHERE
• Lies just below the
lithosphere.
• Does not extend very deep
into the upper mantle.
• State of Matter:
Solid – but has a plastic
feel that allows it to flow
like silly putty.

ASTHENOSPHERE
The Mantle
LITHOSPHERE
MANTLE
ASTHENOSPHERE
• Thickness:

• Temperature:
2800-3200 °C
• State of Matter:

feel that allows it to flow
like silly putty.

OUTER CORE
ASTHENOSPHERE
• Thickness:
