It is most likely that the high pressure in the inner core comes from

the weight of the layers above the inner core.

the part of the Earth's crust that forms land masses.

How is the inner core different from the outer core

the outer core is liquid and the inner core is solid

One can best show Earth's layers by a

peach half, showing the skin, flesh, and pit.
