Answer 1

The core of the Earth is mostly composed of nickel and iron.

Step-by-step explanation:

The core of the Earth is mostly composed of nickel and iron. These elements make up about 85% of the Earth's core. Nickel accounts for about 5-10% of the core's composition, while iron makes up the remaining 90-95%. This knowledge is based on seismic waves and the study of meteorites, which have similar composition to the Earth's core.
