Snow is formed when temperatures are low and there is moisture-in the form of tiny ice crystals-in the atmosphere. When these tiny ice crystals collide they stick together in clouds to become snowflakes. If enough ice crystals stick together, they'll become heavy enough to fall to the ground.
The snowflake is an very simple example of self-assembly. There is no blueprint or genetic code that guides the growth of a snowflake, yet marvelously complex structures appear, quite literally out of thin air. As we understand better how snowflakes form, we learn about self-assembly.
