Earth's thin outer shell; can be oceanic crust (sima) or continental (sial)
1 of 5
The Lithosphere
The crust and upper mantle
2 of 5
The Mantle
Under the crust; 2900km thick; rocks in the upper part are solid, in the lower part they are liquid; convection currents occur here due to heat from the core
3 of 5
The Asthenosphere
The liquid lower part of the mantle on which the tectonic plates float
4 of 5
The Core
The centre of the Earth; temperatures can reach above 5000⁰C; the outer core is semi-liquid and mainly iron; the inner core is solid and made of an iron-nickel alloy; the heat of the core creates convection currents in the mantle
