ryholite
An extrusive igneous rock with a composition similar to granite but with smaller crystals is called rhyolite. Rhyolite forms from the rapid cooling of magma at the Earth's surface, resulting in fine-grained crystals. It is light in color and rich in silica, similar to granite.
If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
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.
When granite melts within the Earth, an extrusive rock called rhyolite forms upon eruption at the surface. Rhyolite is the equivalent extrusive rock to granite and has a similar composition, but it forms from the rapid cooling of magma at the surface rather than slowly solidifying beneath the Earth's surface.
Rhyolite is a fine-grained, extrusive igneous rock with high silica content, while granite is a coarse-grained, intrusive igneous rock also rich in silica but with larger crystals. Rhyolite forms from cooled lava flows on the Earth's surface, while granite forms from slowly cooling magma beneath the surface.

The continental crust is similar in composition to granite. It is the outermost layer of the Earth's surface and is primarily composed of rocks like granite, which is rich in silica and aluminum.
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
Dacite is an extrusive rock that has a composition similar to andesite. Both rocks are rich in silica and belong to the intermediate composition category. They form from the volcanic eruption of magma that is intermediate in composition between felsic and mafic.
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.
Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y
No, intrusive rocks typically have larger crystals due to slower cooling within the Earth's crust, while extrusive rocks have smaller crystals or a glassy texture because they cool quickly on the Earth's surface. The cooling rate affects crystal size in igneous rocks.
