If you were making a three-dimensional model of the chemical composition of Earth, which of these might you include? (1 point) Responses.

Question

A glass marble as the outer core.
A piece of solid wax from a candle as the mantle.
A granite countertop as the crust.
A crumpled up ball of aluminum foil as the inner core.

Answer 1

In creating a three-dimensional model of the chemical composition of Earth, the most appropriate choice from the options provided would be:

• A granite countertop as the crust.

Granite is a common type of rock found in the Earth's crust and represents the continental crust's composition.

The other options do not accurately represent the Earth's layers:

• A glass marble would not correctly represent the outer core, which is composed of liquid iron and nickel.
• A piece of solid wax from a candle does not represent the mantle, which is composed of semi-solid rocks and minerals.
• A crumpled ball of aluminum foil is not representative of the inner core, which is solid and primarily composed of iron and nickel.

Therefore, the granite countertop is the best choice for representing the Earth's crust.
