Why Are Granite And Rhyolite Have Different Apperences

The difference is rhyolite has much finer crystals.

Why are granite and rhyolite have different apperences.

Based on the texture of rocks they are used for various purposes. Rhyolite is found all over the planet but it is uncommon on islands located far from large land masses. Granite is available in black grey orange pink white colors whereas rhyolite is available in grey white light black colors. Here you can know more about texture of granite and rhyolite.

However rhyolite forms as a result of a violent volcanic eruption while granite forms when magma solidifies beneath the earth s surface. They have essentially the same composition. Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. Why do they have very different appearances.

When we have to compare granite vs rhyolite the texture color and appearance plays an important role in determining the type of rock. They are exposed to different weathering conditions during formation. Rhyolite and granite can both have the same mineral composition despite having two different appearances felsic classification of igneous rocks intermediate mafic obsidian basaltic glass extrusive ultramafic texture glassy non crystalline fine grained rhyolite andesite basalt granite diorite gabbro perl. Texture of granite is granular phaneritic whereas that of rhyolite is aphanitic glassy porphyritic.

Appearance of granite is veined or pebbled and that of rhyolite is banded. The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. Granite and rhyolite are 2 types of igneous rocks with the same chemical composition. Granite is plutonic and rhyolite is volcanic.

Will give brainliest if correct. So they have a similar composition but one is volcanic and the other is plutonic. Rhyolite is an extrusive igneous rock having cooled much more rapidly than granite giving it a glassy appearance. Granite is an intrusive igneous rock formed inside the earth and rhyolite is an extrusive igneous rock formed outside the.

They have very similar compositions but one is erupted onto earth s surface and the other crystallises at depth. Rhyolite has a similar composition and appearance to granite. These crystals are so small that they can not be seen by the naked eye.
