In creating a three-dimensional model of the chemical composition of Earth, the elements you choose should ideally represent the different layers and materials found within the Earth.

Among the options provided, the best choice would be:

  • A granite countertop as the crust.

Granite is a common type of rock found in the continental crust and accurately represents the outermost layer of Earth.

The other options may not be as suitable. For example:

  • A glass marble as the outer core does not accurately represent the liquid state of the outer core or its iron and nickel composition.
  • A crumpled up ball of aluminum foil is not representative of the inner core, which is solid and primarily composed of iron and nickel.
  • A piece of solid wax from a candle does not accurately represent the mantle, which is composed mainly of silicate minerals.

In summary, if you had to choose one from the listed items, the granite countertop would be the most appropriate to include as part of the Earth's crust.
