Rhyolite is a rock type that is categorized by mineral composition. Scoria is a textural rock type. Like, Rhyolite can be smooth, or it can be scoria (sharper, bumpier, lots of vesicles).
Think of it as a rock adjective.
No, granite and rhyolite have different chemical compositions. Granite is primarily composed of quartz, feldspar, and mica, while rhyolite is a fine-grained volcanic rock with similar minerals but different proportions of each, resulting in distinct compositions.
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.

Diorite is a rock that has a composition similar to granite, but with a different texture. Both rocks are composed mainly of quartz, feldspar, and mica minerals. Diorite is typically darker in color and has a coarser grain size compared to granite.
Yes. Granite and Rhyolite have the same composition.
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
No, diorite and rhyolite have different chemical compositions. Diorite is a coarse-grained intrusive igneous rock composed mainly of plagioclase feldspar and amphibole, while rhyolite is a fine-grained volcanic rock composed predominantly of quartz, feldspar, and mica.

There are many rocks that share the same mineral constitution with another rock. An example would be rhyolite and granite. Mineralogically they can be equal in composition (even derived from the same magma), yet very different in texture, appearance and method of formation.
Not necessarily. Most scoria is basaltic, but some can be andesitic.
No, not all mineral oil is the same in terms of its composition and properties. Different grades of mineral oil can vary in purity, viscosity, and other characteristics.
Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. They have essentially the same composition. The difference between them is that granite cools slowly underground, forming large crystals while rhyolite cools rapidly above ground after a volcanic eruption forming small crystals or no crystals.
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
Glass doesn't have a crystalline structure, or a specific chemical composition, so it is not a mineral. Obsidian is not a mineral for the same reason.
Yes, it can. Aluminum oxide, saphires or rubys are all the same mineral. Just with minor elemental differences.
