But obviously nobody believed him until another scientist "Harry Hess " helped by giving more proof to his theory almost 50 years later by using evidence of sea floor spreading to explain what moved continents.

Earths crust is actually made of many elements like oxygen( 46.6%) , silicon ( 27.7%), aluminum ( 8.1%), iron ( 5%) , sodium( 2.8%) and so on.

As for the" inner core " it is the deepest , hottest layer (more then 5000 degrees ) it is also a solid because the core material is under extreme  pressure . The inner core has a radius of 1,220 km which is about 20% of Earths radius . The inner core is believed to be composed of an iron - nickel alloy with some other elements .
