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.

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
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 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.
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.
Yes, lithospheric plates can be compared to pieces of an eggshell on a hard-boiled egg. Just as the eggshell is a rigid outer layer that encases the soft interior, lithospheric plates are solid segments of the Earth's crust that float on the semi-fluid asthenosphere beneath. Both structures are rigid and can crack or break under stress, leading to movement or deformation. However, the geological processes governing plate tectonics are much more dynamic and complex than the simple structure of an eggshell.

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.
thinner and denser
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.
