no, extrusive because it is made by lava not magma.
Felsic porphyritic rocks can be extrusive if they are formed from volcanic eruptions. These rocks have a high silica content and typically contain large crystals (phenocrysts) embedded in a fine-grained matrix. Examples of felsic porphyritic extrusive rocks include rhyolite and dacite.
It can be either. "Felsic" is not a specific type of rock but a general description of an ingeous rock's composition indicating high levels of silica and alkali feldspars.
The difference between extrusive and intrsive rocks are thatextrusive rock is a ingeous rock and formes by lava that erupes onto earth surface, and that intrusive rock is igneous rocks that hardenes beeatg earth's surface.
It would be a ingeous rock.
yes
Obsidian, Granite, and i believe slate
Obsidian
Ingeous can be formed in the color yellow, red,ect.
Ingeous
Ingeous
Its extreme heat and pressure would destroy it.
a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
No.It is sedimentary, however anthracite is considered metamorphic. Graphite (chemically pure carbon) can be found in igneous rocks.
Originally from a Latin word Ingeniousus, referring to 'innate qualities'. The word passed into French as Ingeignos and subsequently into English, in the late 15th Century
This is made out of cooling of magma underground this is a major component of the componenntal crust,coarse grained,and composed of guartz along with a variety of feldspor minerals and micas.
