Answer :
Final answer:
Yes, two different igneous rocks can have the same composition but different textures. This is because the texture is determined by the cooling rate of the molten material, not the composition. For instance, granite and rhyolite have the same composition, but different textures due to their cooling rates.
Explanation:
Yes, it is possible for two different types of igneous rocks to have the same composition but different textures. This is due to the fact that the texture of an igneous rock is determined by the cooling rate of the molten material from which it formed, not its composition. For example, granite and rhyolite have the same mineral composition - they are both made up of quartz, feldspar, and mica. However, granite has a coarse-grained texture because it cooled slowly beneath the Earth's surface, while rhyolite has a fine-grained texture because it cooled quickly on the Earth's surface.
