Most felsic rocks, though not all, are intrusive.
Felsic rocks can be either intrusive or extrusive. Intrusive felsic rocks form underground when magma cools and solidifies slowly, creating large crystals. Extrusive felsic rocks form at the Earth's surface when volcanic lava cools quickly, resulting in fine-grained rocks like rhyolite.
The three main groups of igneous rocks are intrusive (plutonic), extrusive (volcanic), and hypabyssal rocks. Intrusive rocks form below the Earth's surface from the slow cooling of magma. Extrusive rocks form on the Earth's surface from rapidly cooling lava. Hypabyssal rocks are intermediate rocks that form from magma that solidifies in the crust.
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
Igneous rocks are described as intrusive or extrusive based on formation. Intrusive rocks forms underneath the earth surface, while extrusive rocks forms on the surface of earth.
Apatite is typically found as an accessory mineral in both intrusive and extrusive igneous rocks. It is more common in intrusive rocks like granite, but can also be found in extrusive rocks like basalt.

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.
Felsic, high in silica. Mafic, low in silica. Intrusive, those formed underground. Extrusive, those formed above ground.

Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.

extrusive
Apatite is typically found as an accessory mineral in both intrusive and extrusive igneous rocks. It is more common in intrusive rocks like granite, but can also be found in extrusive rocks like basalt.
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.
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.
