Can't pick just one. The Earth is made up of many rock types.
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
Igneous rock.
rock
mantle

Lava....when its under the earths crust its called magma.
Yes it is call a crust 😁
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.
The earths crust is moved rather than pulled by things called convection currents. This is when heated rock from the earths core rises up and reaches the crust where it cools. It then sinks down again and carries on in a circle which moves the crust
its called the mantle
Continental plates.
