Ice crystals or flakes that fall from the sky are commonly referred to as snow. Snow forms when water vapor in the atmosphere freezes into ice crystals, which then cluster together and fall to the ground. The unique shapes and sizes of snowflakes depend on various atmospheric conditions during their formation. Snow can accumulate on the ground, creating winter landscapes and impacting weather and climate.
There isn't a factor in clouds that control snowflake formation.Wet snow: water droplets and ice crystals form. Ice crystals grow. Ice crystals combine and form snowflakes. Snowflakes begin to melt. Dry snow:water droplets and ice crystals form. Ice crystals grow. Ice crystals combine snowflakes. Snowflakes fall without melting.
This is precipitation, part of the water cycle.
Clouds form when water vapor in the atmosphere cools and condenses into tiny water droplets or ice crystals. Under cold conditions, particularly in the upper atmosphere, water vapor can directly freeze into ice crystals when temperatures drop below freezing. These ice crystals can collide and stick together, growing larger and eventually forming clouds. When enough ice crystals gather, they can fall as precipitation, such as snow.
The tiny ice crystals that fall from the sky are known as snowflakes. They form when water vapor in the atmosphere freezes into ice, creating unique crystal structures as they descend through varying temperature and humidity conditions. Snowflakes can vary widely in shape and size, but they are generally composed of six-sided (hexagonal) patterns. When these crystals accumulate on the ground, they create snow cover.
White frozen water vapor is called snow. It forms when water vapor in the atmosphere freezes into ice crystals, which then fall to the ground as snowflakes.

Ice crystals that fall from the sky are called snowflakes.
Snowflakes are ice crystals that are simply aggregates of ice crystals that collect to each other as they fall toward the surface. Snowflakes usually fall during the winter season.
no Ice particles fall from the sky but Ice crystals form on the ground.
Ice crystals precipitate as snow. When atmospheric conditions are cold enough, these ice crystals can aggregate and eventually fall to the ground in the form of snowflakes. In warmer conditions, ice crystals may melt and fall as rain instead.
'Sleet' or 'hail'.
Formation of precipitation in cold clouds is called nucleation and involves the process of tiny water droplets freezing into ice crystals. These ice crystals grow in size as they collide with other ice crystals or water droplets, eventually becoming heavy enough to fall to the ground as precipitation.

Water changes into a solid inside a cloud through a process called nucleation, where water vapor condenses onto particles like dust or ice crystals to form ice crystals. These ice crystals then grow as they collide with other water droplets, eventually becoming large enough to fall as snow or hail.
