An Edible Earth

by Emi


For a school project, I had to construct an edible earth. 

For the Crust of the Earth, I used Fillo Dough. Why is this a good representation of the earth's crust? Fillo Dough is hard and firm when layered, yet very thin when compared to pie crust. It flakes away when touched if there is only one layer. There is more than one type of crust (not represented in my model.) The oceanic crust is more compact than the continental crust, it is thinner but more firm.

For the Mantle of the Earth, I used brownie and pudding. Why is this a good representation of the earth's mantle? The brownie is not as hard as the Fillo Dough but still firm. The pudding is not quite a liquid, but not a solid either, so it represents the middle mantle. (It is hard to see in the photo, but the pudding is squished between two layers of brownie.) All three layers of the mantle: lower, middle, and upper, are represented in my model. The upper and lower mantle are both solids, as are brownies, while the middle mantle is a soquid, which I represented with pudding. [Ed note: a soquid is a substance that is not a complete solid nor a complete liquid.]

For the Outer Core of the Earth, I used chocolate syrup. Why is this a good representation of the earth's outer core? Chocolate syrup is a liquid that does not blend with solids.

For the Inner Core of the Earth, I used chocolate chips. Why is this a good representation of the earth's inner core? Chocolate chips are very hard and very hard to crush when they are frozen.

The Lithosphere and Asthenosphere are not represented in my model. The lithosphere is a hard layer that can move while the asthenosphere is a soft layer that allows the lithosphere to move. 

About this contributor: Emi is currently an 8th grade student who loves art and anime, and chocolate (which is why her Edible Earth is mostly chocolate.)
