WebHá 2 dias · Formation of Snow. Water vapour, or water in the form of a gas, condenses into snow high in the clouds. The water vapour in a cloud can freeze to create ice crystals if it is cold enough. About 40 °F (0 °C) to 32 °F (0 °C) is the range at which water vapour crystallises around dust particles in the cloud.

Web20 de dez. de 2024 · Snowflakes are formed when snow crystals high up in the clouds condense. Discover how snowflakes form and what makes them form into different shapes and sizes. Updated: 12/20/2024 WebMost crystals form when a liquid changes to a solid. Water freezing is a familiar example of this process. As water freezes, its molecules line up and join to form ice crystals. Snowflakes are collections of ice crystals. Crystals also form when a liquid with matter dissolved (melted) in it dries up.

Snowflakes nucleate around mineral or organic particles in moisture-saturated, subfreezing air masses. They grow by net accretion to the incipient crystals in hexagonal formations.
