* Iron (Fe): This is the most abundant element, making up about 88% of the outer core.

* Nickel (Ni): The second most abundant element, comprising around 5.5%.

* Other elements: While less significant, other elements present include sulfur (S), silicon (Si), and oxygen (O).

It's important to note that the outer core is in a liquid state due to the intense heat and pressure within the Earth. This liquid metal is constantly moving, creating electrical currents that generate Earth's magnetic field.
