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

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

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

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

Layer of the Mantle

(asthenosphere) that

which move very slowly in response to

the ldquoconvectingrdquo part of the mantle
