Interior of Earth Graphic Organizer
Directions: Using your notes and information below, create a graphic organizer that illustrates and
explains how the Earth is layered and how the layer’s interact. Be sure to be accurate and include color!
Include all of the following:
Inner Core composition, thickness, & state of matter
Outer Core  composition, thickness, & state of matter
Upper Mantle composition, thickness, & state of matter
Crust  composition, thickness, & state of matter
Lithosphere
Asthenosphere
Continental Crust
Oceanic Crust
Middle Mantle
Lower Mantle
Convection Currents (illustration)
Earth has a diameter of about 12,756 km (7,972 mi). The Earth's interior consists of rock and metal. It is
made up of four main layers:
1) the inner core: a solid metal core made up of nickel and iron (2440 km diameter)
2) the outer core: a liquid molten core of nickel and iron
3) the mantle: dense and mostly solid silicate rock
4) the crust: thin silicate rock material
The temperature in the core is hotter than the Sun's surface. This intense heat from the inner core causes
material in the outer core and mantle to move around.
The movement of material deep within the Earth may cause large plates made of the crust and upper
mantle to move slowly over the Earth’s surface. It is also possible that the movements generate the
Earth's magnetic field, called the magnetosphere.
