a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
Igneous rocks are rocks that form from the cooling of magma or lava, and "igneous" is derived from the Latin word for "fire." Examples of igneous rocks include basalt, granite, and pumice.
A sedimentary rock can become an igneous rock through the process of melting and solidification. If sedimentary rocks are subjected to high temperatures and pressures in the Earth's crust or mantle, they can melt and form magma. This magma can then cool and solidify to form igneous rocks.
Molten rocks, known as magma, are found near volcanoes because they originate from deep within the Earth's mantle. The extreme heat and pressure in the Earth's interior cause rocks to melt and form magma, which can rise to the surface through volcanic activity, creating volcanoes.

No.It is sedimentary, however anthracite is considered metamorphic. Graphite (chemically pure carbon) can be found in igneous rocks.

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.
yes
It would be a ingeous rock.
Metamorphic rocks can form from both igneous and sedimentary rocks

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.
