which property is used to identify the origin of an igneous rock?\ncolor\ndensity\nhardness\ncrystal size
Answer

Brief Explanations:
Crystal size helps identify igneous - rock origin. Slow cooling (deep - within Earth) gives large crystals; fast cooling (near surface) gives small crystals. Color, density, and hardness are less indicative of origin.
