Also known as snowfall, snowfalls
Snow consists of individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide, or sublimate away.
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.
