Compare and contrast granite and rhyolite

Both granite and rhyolite are the same genetically, however, the difference is that one is volcanic and the other is plutonic. Volcanic or extrusive igneous rock refers to a rock, which dissociates via the surface to crystallize close to or on the surface of the Earth leading to the formation of a fine-grained rock, one of the examples of this is rhyolite.  

On the other hand, a plutonic igneous rock is the one, which crystallizes deep in the crust, and are featured by the formation of coarse-grained rock or comprising large crystals. These rocks are also known as intrusive rocks, and granite is one of the examples.
