Igneous Rocks: Crystallization and Cooling Rate

time to arrange into a fixed, ordered pattern. 5. Igneous rocks form from the process of solidification, but not all igneous rocks have crystals. The environment in which they form on Earth determines the crystal size. Igneous rocks that cool on Earth's surface are extrusive and do not have a crystalline structure because they cool quickly.

The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. Such factors are controlled by the process which formed the rock. Because igneous, sedimentary, and metamorphic processes are distinct, so too the resulting textures are distinct.
