Earth is made of many different materials. I will list a few for each layer of Earth
Crust- The crust has two parts, the oceanic and the continental. The continental part is made off rock.
Mantle- The mantle includes magma. There are also rocks and minerals down there has well
Outer Core- The outer Core is all magma from what I remember. With a little iron in the mix.
Inner Core- It is a iron ball. It is solid because of the intense pressure on the inner core
