Apples - food photography is an art form, and so sometimes the composition, colors, interesting details are more important than whether you'd eat it or not. I wouldn't eat that apple, but I love the photo.
Snowflakes or snow crystals form when ice crystals freeze around tiny particles of dust that are in the air, and join together as they fall. Ice crystals that melt as they fall become rain. Ice crystals that form near the ground are called frost.
