The lithosphere/crust (which is made of tectonic plates). However, the plates are NOT rigid and to describe them as such would be incorrect, they deform and fold.
That is called the "crust".
The crust.
the valence shell
This is called the valence shell
the crust
If you mean, thin layer of air, or thin gaseous layer surrounding the earth then the answer is; Atmosphere. But if not, then the other thin layer of earth is; The crust, but its a solid layer.
lithosphere
the valence shell
The name most often given to the outermost shell of electrons in the context of atomic structure is the valence shell.
The crust is the outermost solid shell of the planet. It is chemically different from the underlying mantle. The scientific name for the crust is the lithosphere. It has an average thickness of 30-35 kilometers in continental areas and 5 kilometers in oceanic areas.
Electrons in the outermost shell are valence electrons!

the elements which have 1, 2 or 3 electrons in their valence (outermost)shells are most likely to lose electrons compared to the other ones and we name them as metals and alkaline earth metals. these elements want to give their outermost shell electrons to become more stable. because when they give those electrons the next shell under this one which has 8 electrons (2 in some cases such as lithium) becomes the new valence shell so the electron configuration resembles a noble gas.
