Question: what is the earth made of?

Naomi Osborne answered on 19 Jun 2014:

Earth is made of 4 layers –

1. Core – the center is extremely HOT and made of iron and nickle
2. Outer core – also iron and nickle but not so hot
3. mantle – third layer which is made of magma (or lava) – this is what comes out of volcanoes
4. crust – thick rock layer made of igneous, metamorphic and sedimentary rock.

Hope this answers your question!
