Difference between Volcanic and Extrusive

VOLCANIC vs EXTRUSIVE: NOUN

That which is extruded; specifically, in petrography, same as effusive (which see): contrasted with intrusive.
Rock which has been formed through volcanic extrusion.

Explosively unstable
Igneous rock produced by eruption and solidified on or near the earth's surface; rhyolite or andesite or basalt
Of, resembling, or caused by a volcano or volcanoes.
Produced by or discharged from a volcano.
Characterized by the presence of volcanoes.
Powerfully explosive.
Of or pertaining to a volcano or volcanoes.
Produced by a volcano, or, more generally, by igneous agencies.
Changed or affected by the heat of a volcano.
A mass ejected from a volcano, often of molten lava having a rounded form.
A hill, conical in form, built up of cinders, tufa, or lava, during volcanic eruptions.
The subterranean centers of volcanic action; the points beneath volcanoes where the causes producing volcanic phenomena are most active.
The vitreous form of lava, produced by sudden cooling; obsidian. See Obsidian.
Fetid, sulphurous mud discharged by a volcano.
Rocks which have been produced from the discharges of volcanic matter, as the various kinds of basalt, trachyte, scoria, obsidian, etc., whether compact, scoriaceous, or vitreous.
Reminiscent of a volcano; explosive, violent, full of suppressed anger, energy etc.
Relating to or produced by or consisting of volcanoes

Of rock material; forced out while molten through cracks in the earth's surface
Derived from magma poured out or ejected at the earth's surface. Used of igneous rocks.
Forced out at the surface; ; -- contrasted with intrusive.
Jutting out; extruding.

Rhyolite or andesite or basalt
Pertaining to or produced by volcanoes or volcanic action: as, volcanic heat, volcanic rock, volcanic phenomena, etc.

Of rock material
Capable of being extruded or thrust out; that tends or serves to extrude or thrust out or forth; specifically, in petrography, erupted or extruded: applied to igneous rocks. Same as effusive.

Volcanic Ash Advice: Drinking Water What is Volcanic Ash?
Potential uses of VOLCANS range from quantitative volcanic hazard assessment to promoting fundamental understanding of volcanic processes.
Pseudotachylytes have, until now, rarely been noted in exogenous volcanic materials and seldom in active volcanic environments.
Andean Southern Volcanic Zone: evolution from volcanic arc front to behind the front type volcanism.
The volcanic glasses are distributed in areas of recent volcanic activity throughout the world.
We also found several thick volcanic ash layers, which might have originated from volcanic eruptions in northern Sulawesi.
Although volcanic eruptions pose considerable hazards to humans, past volcanic activity has created important economic resources.
Therefore, volcanic ash, although released sporadically during volcanic eruptions, is an abundant atmospheric species.
Volcanic mountains are formed in areas where there is volcanic activity.
