Heath broke a jawbreaker candy in half using a hammer. He noticed that the layers in the jawbreaker could be like a model for the crust, mantle, outer core, and inner core of the Earth.

Question

What is one limitation of using the jawbreaker shown above as a model for Earth's layers?
A.
The layers are all made out of the same material.
B.
The jawbreaker has four different layers.
C.
The outside layer is the thinnest layer.
D.
The jawbreaker can be split to show the inside.

Answer 1

A. The layers are all made out of the same material.

This is a key limitation of using a jawbreaker as a model for Earth's layers, as the Earth's layers are composed of different materials with varying properties, while a jawbreaker is made from a single type of candy material.
