The rocks of the crust are igneous, sedimentary, and metamorphic in origin. The base rock of the oceanic crust are mainly basaltic and the base rock of the continental crust is mainly granitic.
they were and aree forced through earths crust in the form of lava.
Silicon
the crust and the core
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

Metamorphic rocks form deep underground under high pressure and heat conditions, typically within the Earth's crust. They can also form at plate boundaries where tectonic forces cause rocks to be buried and subjected to these extreme conditions.
it is made of rocks
a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
Basalt and limestone.
