q1. the core of the earth is primarily composed of ____________.
iron and nickel
iron and silicon
oxygen and carbon dioxide
carbon and nickel
carbon and silver

Explanation:

The Earth's core is mainly made of iron and nickel. This is based on scientific evidence such as seismic wave analysis and the Earth's magnetic field (which is generated by the movement of molten iron - nickel alloy in the outer core). Silicon is more abundant in the Earth's crust and mantle. Oxygen and carbon dioxide are not the main components of the core. Carbon is not the dominant element in the core, and silver is a relatively rare element in the Earth's interior compared to iron and nickel.

Answer:

Iron and Nickel
