If earth was like a hardboiled egg, which part of earth would the egg shell represent and why? a. crust, as its depth is up to 3,000 kilometersb. mantle, as its depth is up to 3,000 kilometersc. mantle, as its depth is less than 100 kilometersd. crust, as its depth is less than 100 kilometers

D. Crust, as its depth is less than 100 kilometers

Explanation:

Crust is about 1 % of the earth depth(less than 100 kilometers) which is almost insignificant compared to the earth total depth.

The analogy of a hard boiled egg shell fits well into the earth crust description  because of how insignificant the depth of the shell is compared to the whole egg depth.
