AI overview
Snow is frozen water that forms as ice crystals in clouds, grows larger, and falls to accumulate on the ground, where it continues to change over time. It matters because it represents a significant part of Earth's water cycle, undergoing transformations from its initial crystalline formation through melting, sliding, or evaporation.
