The Water Cycle
The water cycle has no beginning or end and is a constant state of flux. Water changes it states from liquid, to vapor, to ice and then back again. These processes happen in the blink of an eye and over millions of years. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go in a hurry.
Our water cycle graphic describes this continuous movement of water on, above and below the surface of the Earth as it makes its journey to your tap.
