Heart of iron
Our planet possesses a heart of iron that lies buried 5,000 kilometres below our feet. It is roughly the same size as the dwarf planet Pluto and it grows minutely every year, playing a crucial role in powering Earth’s magnetic field which protects us from radiation from outer space
Inner core
Outer core
Mantle
Crust
The temperature and pressure in the inner core reach 6,000C and 3 million atmospheres. The iron is solid here. Above it, lies a molten outer core and above that lies Earth’s mantle, a 3,000 kilometre thick layer of silicate rock. Finally, there is the crust at the outer edge of our planet. This provides homes for Earth’s living creatures and is made up of a thin layer of rock
