Layers of the Earth Outer Crust Inner Crust Mantle Outer Core Inner Core Crust
Inner Core 750 mile radius Outer Core 1,430 miles Mantle 1,800 miles Crust (10-25 miles) Inside Our Earth
The inner core is made of solid nickel and iron. The outer core is made of hot liquid nickel and iron. The crust is made of soil, water and rock. The mantle is hot part melted and part solid iron and magnesium. Composition of the Earth’s Layers
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 semi- liquid 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.
