Inside Our Earth

Page 5: Journey to the Center of Earth Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust.

The inner core is made of solid nickel and iron.

The outer core ismade of hot liquid nickel and iron.

The crust is made of soil, water and rock.

The mantle is hot partmelted and part solidiron and magnesium.

Composition of the Earth’s Layers

Page 6: Journey to the Center of Earth Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust.

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

Page 7: Journey to the Center of Earth Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust.

The Mantle

• This layer is semi- liquid

• It consists of magnesium, iron, and silicon

• It is 3000 km wide• It is more solid closer

to the surface

Page 8: Journey to the Center of Earth Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust.

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

Page 9: Journey to the Center of Earth Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust.

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.
