Why are extrusive rocks sometimes referred to as volcanic?
An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks. However there are also volcanoes to be found that have nothing to do with molten rock magmas. These are called "Mud" volcanoes and they are caused by de-watering processes in rocks. The muds brought to the surface are also technically extrusive and these are NOT volcanic rocks.
