rhyolite
Rhyolite is felsic and thus silica rich.
basalt
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
There are rocks that are extrusive (formed quickly on the surface of the earth) or intrusive (formed within the earth under slow cooling). Both types of extrusive or intrusive rocks can vary in composition from mafic (high iron and magnesium content) to silicic (less heavy ions like Fe and Mg, but with more of the lighter elements like Ca, Na, K, etc.). Extrusive rocks range from most mafic to less mafic as such: Basalt, Andesite, Rhyolite (and are all fine-grained b/c they cooled quickly). Intrusive rocks that cool more slowly and have larger crystals range from most mafic to less mafic as such: Gabbro, Diorite, Granite. Basalt and gabbro have a similar composition, just the crystal size differs from different cooling rates (same for rhyolite and granite).
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
Of these Rhyolite has the highest silica content.
No. Basalt is a low-silica igneous rock while rhyolite is high-silica. As far as volcanic rocks go, they are essentially opposites.
Rhyolite has a more felsic composition than basalt.
Granite has more silica than basalt in it.
Granite is higher in silica than is basalt.
Rhyolite is felsic and thus silica rich.
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
