Which elements are mainly found in the Earth's core?

Answer and explanation

Correct answer: Iron and nickel

The Earth's core is considered to be composed mainly of iron and nickel, so it is often called NIFE (Ni + Fe). Silica and alumina are associated mainly with materials of the crust and mantle, not the core. Exam tip: remember NIFE as nickel plus ferrum (iron).
