Answer 1

In a three-dimensional model of the chemical composition of Earth, the most appropriate choices would be:

• A granite countertop as the crust, because granite is a common type of rock found in the Earth's continental crust.

The other materials you mentioned (solid wax for the mantle, a glass marble for the outer core, and aluminum foil for the inner core) are not suitable representations of those layers in terms of composition and physical state.

So, the best inclusion from your options for representing Earth’s layers is a granite countertop as the crust.
