Name the layer of the Earth that is about 2200 kilometres (1367 mi) thick, composed mostly of nickel, iron, and molten rock and where temperatures can reach up to 5,000°C?

* The Outer Core is a fluid layer about 2,200km thick, situated beneath the mantle and surrounding the solid inner core.
It is composed primarily of a liquid mixture of iron and nickel, where extremely intense heat conditions generate a fluid temperature dynamic ranging up to 5,000
∘
C. The convective motion within this liquid metallic layer gives rise to Earth's magnetic field.
