Earth’s crust and mantle are mostly made of minerals called silicates, which are a combination of silicon dioxide and metal oxides. The mantle is rich in magnesium-containing silicates, while the two different types of crust have less magnesium and more aluminum and calcium. The core is dominated by metallic iron. No part of it has ever been brought to the surface, but its composition has been worked out by scientific methods such as studying earthquake waves.
I think It's cool to see how any rock can become any rock at any time just by going through a different transformation. Lakesha Fisher GOL 105 Fall 2018
Dude you dont know how the earth was formed there are only theories and speculations. You should mention that instead of making someone think of it as fact.
