In its liquid state as we most commonly know it, it is called water. In its solid state, water is known as ice. In its gaseous state, water is called steam or vapor. You can feel water vapor in the air on a hot and humid day. You can see water vapor condense against a cold glass of milk.
Water is recycled again and again in the hydrologic cycle.
Water accumulates, or gathers, in lakes and oceans. When water reaches its vapor point, it evaporates into the air. As water vapor rises into the upper atmosphere, its temperature is lowered by the cooler air. When it is cooled enough, the water vapor forms into tiny water droplets. This process is called condensation.
