Final answer:

Metallic meteorites are indicative of the Earth's core composition being mainly iron and nickel.


Explanation:

One piece of evidence to support the idea of Earth's core being iron is that metallic meteorites are thought to be representative of the core. The 85% iron and 15% nickel composition seen in metallic meteorites aligns with the estimated core composition. This similarity in composition provides valuable evidence supporting the notion that the Earth's core is primarily made of iron and nickel.
