isostasy
The earths crust is a part of the outermost layer.
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.

how wide is the earths crust
The abundance of neodymium in the earths crust is approx. 40 ppm.
it is concept of earths crust is gravitational balance or equilibrium.
An isostatic is something that pertains to or is characterized by isostasy. Isostasy is the equilibrium of the Earths crust.
Isostacy refers to an equilibrium level maintained by the earths crust on top of the mantle. The theory holds that the weight of the earths crust will displace a certain amount of the underlying mantle, and that an equilibrium is reached whereby the mass of the displaced crust and the mass of the displaced mantle are equal, thus holding that part of the crust at a certain height.
Isostasy
the earth will lose it's gravitational field or the crust and the outer core will start to move inwards because of the earths gravitational field
An increase in weight to the crust due to thickening from plate collisions, build up of sediments, or glacial override will necessitate a corresponding downward movement into the ductile asthenosphere in an attempt to achieve gravitational equilibrium as it applies to the difference in buoyancy between the different Earth layers.. As this weight is removed through erosion or glacial retreat, the crust will gradually rebound to achieve equilibrium.

Isostatic equilibrium is the balance between Earth's crust and the layer of mantle it floats on. The denser the crust is, the more it sinks into the mantle. Equilibrium is achieved when the crust floats at a certain level in the mantle.

The Earths crust is approximately 650 km deep.
does the moon's gravitational force affect the crust of the earth?
