When moisture is present in the atmosphere and temperatures are low enough, ice crystals will form and continue to combine with each other until the matter is heavy enough to actually fall to the ground.
Inside a cloud, tiny ice crystals latch onto very tiny particles of dirt or debris. When the matter is heavy enough, it falls.
Hope this helps you with understanding weather function.
