What is one similarity between Granite and Rhyolite?

Answer 1

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.

Answer 2

Granite and rhyolite have essentially the same composition. Both are felsic igneous rocks, meaning they form from molten rock that is rich in silica, sodium, potassium, and aluminum. Both are generally light-colored. They are different in texture and how they form. Granite is an intrusive or plutonic rock. It cools slowly underground and forms fairly large mineral grains. Rhyolite is an extrusive or volcanic rock. It cools at the surface after erupting from a volcano and cools quickly. Depending on how quickly it cools it may have microscopic mineral grains or none at all.

Answer 3

Both granite and rhyolite are felsic igneous rocks with roughly the same amount of silica. The main difference between the two is granite forms beneath the surface where it has sufficient amount of time to crystallize. It manifests larger crystals within the rock. Conversely, rhyolite forms on the surface where it cools rapidly and therefore does not have time to crystallize the way granite does forming smaller crystals resulting in finer-grained texture.

Answer 4

they have the same chemical composition and they are igneous rocks.
