How Snowflakes Form

Delicate scientific infographic poster 'HOW SNOWFLAKES FORM' featuring a large central diagram of six snowflake crystal classes—stellar dendrite, plate, column, needle, bullet rosette and irregular—each drawn as a precise flat vector crystal on a dark navy background, with thin white labels and formation-temperature badges from -2°C to -25°C. A small circular water-cycle inset in the upper-right corner shows evaporation, cloud formation and freezing. Color palette: ice blue #81D4FA, glacier white #F5FDFF, deep navy #0B1B3D, frost silver #E0E0E0, with pale violet #B39DDB accent on the dendrite branches. Layout with a delicate radial snowflake ornament border, subtle frost-vein background texture, soft cool glow from the crystals, crisp sans-serif typography, clean three-level data hierarchy, fine print finish, 4k
