An eggshell can be compared to the crust of the Earth because both serve as protective outer layers. Just as the eggshell safeguards the delicate contents inside, the Earth's crust protects the molten mantle and core beneath it. Additionally, both structures are relatively thin compared to what lies beneath, yet they play crucial roles in maintaining the integrity of their respective systems. This analogy highlights the importance of these outer layers in providing stability and protection.
younger
I'm not sure what you mean by egg model, but if your talking about an egg representing the Earth, the eggshell would be the crust because the egg white is the mantle and the yolk is the core.
thinner and denser
The crust not under the ocean is called continental crust. It is thicker and less dense compared to oceanic crust and forms the landmasses on Earth's surface.
Compared to continental crust, oceanic crust is generally thinner, denser, and younger. It typically has an average thickness of about 5-10 kilometers, while continental crust can range from 30 to 50 kilometers. Oceanic crust is primarily composed of basalt, whereas continental crust is mostly granite. Additionally, oceanic crust is continuously being formed at mid-ocean ridges, making it geologically younger than most continental crust.
The "Crust" is one of the Earth's layer.It can be compared to an eggshell
The eggshell corresponds to the crust of the Earth. Both the eggshell and the Earth's crust are the outermost layers that provide protection and structure to what lies beneath them.
An eggshell is the hard, white or brown outside, or you could call it crust, that encircles the yolk and white of the egg.
younger
The relative thickness of the Earth's crust is similar to the relative thickness of an apple's skin compared to the apple itself. Both the Earth's crust and an apple's skin are thin outer layers in relation to the entire object.

Iron and magnesium, when compared to continental crust.
Eggshell
The lower crust is denser and more mafic in composition compared to the upper crust, which is less dense and more felsic. The lower crust is also usually deeper in the Earth's crust compared to the upper crust.
The eggshell is porous.
The composition of the continental crust is granitic overall, high in silicon and aluminum, when compared to the oceanic crust.
