Question

why is the composition of the srystal layer of the earth of great interest ​

Answer 1

$\huge{\underline{\rm{\red{Answer}}}}$

The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. The force exerted by Earth's gravity can be used to calculate its mass.
