Water Cycle - Rivers [720p]

Water regulates climate, storing heat during the day and releasing it at night. Water in the ocean and atmosphere carry heat from the tropics to the poles. The process by which water moves around the earth, from the ocean, to the atmosphere, to the land and back to the ocean is called the water cycle.

In this animation, pulsing of the global rivers highlights the flow of water from the continents back into the oceans.
