What type of rock can be extrusive or intrusive?

Is diorite intrusive or extrusive?
Diorite is an intrusive igneous rock, formed from the cooling and solidification of magma beneath the Earth's surface. It contains a mix of minerals such as plagioclase feldspar, biotite, hornblende, and pyroxene.
Is feldspar extrusive or intrusive?
Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
What is the difference between an intrusive and an extrusive igneous rocks?
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.

How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
