Which of the following pairs of elements are found in the core of the Earth?

The core of the Earth is composed primarily of Iron and Nickel, with small amounts of other elements such as Silicon, Sulfur, and Carbon. These elements are found in the Earth's core because they are dense and able to withstand the immense pressure and high temperatures found at the center of the planet. The combination of Iron and Nickel creates an alloy that is even denser and stronger, making it the ideal material for the Earth's core.
