That would be andesite, as it is extrusive. The intusive rock with the same composition is diorite.
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
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.
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.
There are many varieties of igneous rock. Igneous means it formed as a result of volcanic activity (the word igneous comes from the same root word as ignite) which produces extreme heat. Two main types of igneous rocks are intrusive (cooled gradually underground) and extrusive (cooled more rapidly at or near the surface.) Common examples of igneous rocks include granite, pumice, obsidian, basalt, diorite, andesite.
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 and andesite are both igneous rocks, but they have different mineral compositions and origins. Diorite is a coarse-grained rock composed mostly of plagioclase feldspar and hornblende, while andesite is a fine-grained rock with a mix of plagioclase feldspar and mafic minerals like amphibole or pyroxene. Andesite typically forms from intermediate magmas in volcanic settings, while diorite forms from the slow cooling of molten rock deep beneath the Earth's surface.
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 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).
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
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.
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.
The volcanic equivalent of norite is andesite. Both rock types are classified as intermediate in composition, with norite being a plutonic igneous rock and andesite being its volcanic counterpart formed from the same magma source.
Other than that they are both types of rock, very little. They have very different methods of formation and mineral composition. Basalt is produced from mafic lava flows, and shale is a product of sedimentary rock processes.

No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
