Layers of the Earth
Watch the movie trailer for Journey to the Center of the Earth Identify characteristics that you think are true and those you think
are not true Be prepared to share

Essential Question How are layers of the Earth different from one another
Standard
S6E6a Compare and contrast the Earthrsquos crust mantle and core including temperature density and composition
The Earth is made up of 3 main layers
Crust
Mantle
Core
Think of the layers of the Earth like the layers of a cake
Crust
Ocean Land
bull Thinnest layer of the Earth that ranges from only 2 miles in some areas of the ocean floor to 75 miles deep under mountains
bull Made up of large amounts of silicon and aluminum
bull Two types of crust oceanic crust and continental crust
bull Composed of plates on which the continents and oceans rest
Ocean Land Crust
The Earthrsquos crust is like the skin of an apple Turn to an elbow partner and discuss why this statement is true
Next come up with another example
Mantle
Upper Mantle
Lower Mantle
Middle Mantle
Convection Currents
bull Solid but capable of flow (like hot asphalt or fudge)
bull Thickest layer of the Earth (making up 70 of the Earthrsquos mass)
bull The hot material (magma) in the mantle rises to the top of the mantle cools then sinks reheats and rises again These convection currents cause changes in the Earthrsquos surface
Upper Mantle
Convection Currents
Middle Mantle
Lower Mantle
Mantle
Core
Inner Core
Outer Core
Outer Core
bull Molten (liquid) metal that is about 4700degC (8500degF)
bull Located about 1800 miles beneath the crust and is about 1400 miles thick
bull Composed of the melted metals nickel and iron
Inner Core
bull Solid sphere composed mostly of iron
bull It is believed to be as hot as 6650degC (12000degF)
bull Heat in the core is probably generated by the radioactive decay of uranium and other elements
bull It is solid because of the pressure from the outer core mantle and crust compressing it tremendously
The Earth is like a peach or a boiled egg Turn to a seat partner and discuss these
analogies Come up with another analogy and be prepared to share
Inner Core
Solid
Outer Core
Liquid
Mantle
Crust
Lithosphere ndash Crust and
Upper Layer of the Mantle
Layer of the Mantle
(asthenosphere) that
consists of hot rock of
tar-like consistency
which slowly moves
The lithosphere (crust and upper
mantle) is divided into separate plates
which move very slowly in response to
the ldquoconvectingrdquo part of the mantle
What do these two images tell us about the layers of the Earth
Temperature increases as depth increases
Look at the information in the graph and
table below Whatrsquos the relationship
between depth and densitypressure
Density and Pressure increase as depth increases
Add this statement to the
arrow going down on your
foldable
Temperature Density and
Pressure increases as depth increases
Which layer of the Earth has the
greatest temperature pressure and
density
Core
The earth is layered with a lithosphere (crust and uppermost mantle) convecting mantle and a dense metallic core
