PRESENTATION OUTLINE

EARTHS COMPOSITION

Core
The inner core is shaped like a ball. Scientists say the outer core is made mostly of iron and nickel. Iron and nickel are two important metals found everywhere on the planet.

Mantle
The mantle is a layer between the crust and the outer core. Earth's mantle is a silicate rocky shell about 2,900 kilometres (1,800 mi) thick that constitutes about 84% of Earth's volume.

Crust
In geology, the crust is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle.

Facts on core
It makes up 19 percent of the Earth's total volume.The temperature of the inner core is estimated to be between 3,000 and 5,000 Kelvin (4,940 to 8,540 degrees Fahrenheit)

Facts on mantle
The average temperature of the mantle is 3000° Celsius. The temperature of the mantle will become much hotter as you get closer to the Inner Core.The mantle is about 2900 km thick.

Facts on crust
The Crust's thickness can vary from wherever you are. From a continent to the edge of the crust is about 60 km. From the bottom of the ocean to the edge of the crust is about 10 km. The Crust's temperature is different throughout the entire crust. The temperatures start at about 200° Celsius and can rise up to 400° Celsius.
