Liquid iron and nickel make up the outer core of the Earth.
the molten iron core
The inner core of the Earth is composed of solid iron. The outer core is made up of molten metals, primarily a nickel-iron alloy.

The two heavy metals that make up Earth's core are iron and nickel. They are believed to be primarily responsible for the Earth's magnetic field.

The outer core of the earth is made of liquid metals, mostly nickel and iron. It contains small amounts of oxygen and sulfur.
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
The Earth's core is not made up of rocks. It is made up primarily of nickel and iron.
The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
The Earth's core is thought to be predominantly iron (85 %) with some (4-5%) nickel and the remainder oxygen, silicon, hydrogen and carbon and a number of siderophile (iron liking) elements that descended to the core with iron during planetary differentiation.
The metal called 'Iron'. Fe The Earth's core is believed to consist largely of an iron-nickel alloy. Iron and nickel are, of course, two metallic elements. They ended up in the earth's core because of how dense they are.
The inner core is predominately iron, with some nickel, and trace lighter elements, as far as we can deduce from current science.
