Outer Crust

Mantle
Outer Core
Inner Core
Outer Crust
• This is the layer that we live on
• The thickness ranges from five miles under
the oceans to 25 miles under the continents
• Consists of cooled rock
• It is the thinnest layer of the earth
The Mantle
• This layer is semiliquid
• It consists of
magnesium, iron, and
silicon
• It is 3000 km wide
• It is more solid closer
to the surface
The Outer Core
• This is consists of liquid due to the high
temperatures
• It is 2100 km wide
• This layer consists of nickel and iron
The Inner Core
• This layer is solid.
• The reason it is solid is due to the high
pressure exerted on it from the outside
layers.
• It consists of the metals nickel and iron.
• Its temperature is 6,000 degree Celsius.
• Its width is 2,100 km.
Activity # 1- Making a
Cross Section
• Identify the layers of the
earth (crust, mantle, outer
core, and inner core).
• Look at an apple
• Identify the skin (crust)
• Identify the apple (mantle)
• Identify the outside of the
seeds (outer core).
• Identify the inside of the
seeds (inner core).
Activity #2- Making Flash
Cards
• Listen to the book “Magic
School Bus- Inside the
Earth.”
• Make a list of the earth’s
characteristics.
• Get into groups of four.
• Make flash cards using the
information form the
book.
• Quiz each other and see
who gets the most correct.
Activity #3- Making a
Model of the Earth
• Review the
characteristics of the
layers of the earth.
• Choose four facts that
you wish to discuss.
• Make a poster of the
earth, its layers, and
the information that
you chose.
Assessment
• Have students present
his/her poster or earth
creation.
• Grade them on the
responses to the
flashcards.
• Play a game that involves
questions about the crust,
mantle, outer core, and
inner core.
