What do all intrusive igneous rocks start out as?

Melted Rock (Magma), Then cools to form igneous rock.

What causes sedimentary rock?

Sediment that was accumulated is pressed together.

What is the process of the formation of Extrusive Igneous Rocks?

Magma erupts onto earth's surface and cools quickly.
