Snow is the result of moisture and low temperatures colliding; when they collide, they become tiny ice crystals. When ice crystals stick to one another, they become snowflakes. Snow is important to the water cycle because when they precipitate to the earth, they start to melt on surfaces warmer than themselves. The melted result becomes water, and when the water either seeps into the ground or flows into a source of water nearby, the water cycle's process repeats all over again.
