Question

An igneous rock forms quickly. Which characteristic could the rock have? Responses smooth, sharp texture smooth, sharp texture - no response given small sand grains small sand grains - no response given large mineral crystals large mineral crystals - no response given evidence of folding

Answer 1

An igneous rock that forms quickly typically has **small sand grains** or a fine-grained texture. This is because rapid cooling does not allow large crystals to form, resulting in a smoother appearance with smaller mineral grains. Therefore, based on the options provided, the characteristic of having **small sand grains** would be the most appropriate response.
