Answer 1

If an igneous rock forms quickly, it is likely to have smooth, sharp texture. Fast cooling typically results in smaller mineral crystals, often giving the rock a glassy appearance. This indicates a rapid formation, which aligns with the characteristic of having a smooth texture rather than large mineral crystals.
