Yes. Volcanic rocks are extrusive igneous rocks.
No, igneous rocks are harder than sedimentary rocks on average.
extrusive igneous rocks =/
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
Yes. More exactly, intrusive igneous rocks.
