Is ice a rock?
gpt
Yes, a rock is an aggregate of one or more minerals. So a lump of single mineral counts as a rock. So then the question is, is ice a mineral? The modern definition excludes things that aren't solid at room temperature, but traditionally ice has been classified as a mineral and so it is still included in international mineralogical classifications.
