How snowflakes are formed

Snow crystals form in clouds when water vapor condenses directly into ice.

Flakes aren’t frozen raindrops ” when raindrops freeze they form sleet or hail, without any of the patterns found in snow.

When a water droplet freezes in a cloud, it becomes a crystal and is surrounded by other liquid water droplets, forming a flake.



The most simple snow crystal is a hexagonal prism. Different temperatures dictate the shape of the prism, creating anything from a hexagonal plate to a long column.

Snow crystals can also form around other particles floating in the air, like clay, dust, silica, volcanic ash, or meteor fragments.
