How does the earth’s crust compare to other layers of the earth in terms of thickness and density?

The structure of the earth divides into three main layers, the core that is the innermost, the mantle, and the crust. The earth's crust is the last solid layer of the planet, it has a thickness of between 5km and 70km.

It is the thinnest layer compared to the others that have thicknesses of hundreds to thousands of kilometers.

The crust is also the least dense layer compared to the mantle and the core.

It has an average density of , while that of the mantle is and that of the core is on average .

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

neither accurate nor precise.
