Which model closely

Question

resembles the thickness of the
crust relative to the rest of the
earth?
The crust is like
caramel around a
caramel apple.
The crust is like the
peel of a grapefruit.
The crust is like the
shell on a hard-boiled
egg.
The crust is like the
yogurt around a
yogurt-covered raisin.

Answer 1

To determine which model closely resembles the thickness of the Earth's crust relative to the rest of the Earth, consider the scale of the thickness of the Earth's crust compared to the entire planet.

The Earth has a radius of about 6,371 kilometers, while the crust is only about 5 to 70 kilometers thick, depending on whether it's continental or oceanic. This makes the crust incredibly thin compared to the overall size of the Earth.

Among the options provided:

1. Caramel around a caramel apple - This suggests a relatively thick layer of caramel compared to the full apple.
2. Peel of a grapefruit - The peel is somewhat thicker compared to the size of the grapefruit.
3. Shell on a hard-boiled egg - The shell is relatively thin compared to the size of the egg.
4. Yogurt around a yogurt-covered raisin - The yogurt is thick relative to the small raisin.

The best analogy, considering the comparison of thickness, is the shell on a hard-boiled egg. This model adequately represents the relatively thin crust compared to the rest of the Earth, as the shell is thin compared to the overall volume of the egg.
