This visualization, from the US Geological Survey, provides a simple schematic of the various pathways that water can take as it cycles through ocean, lakes, atmosphere, surface and ground.
This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.
This is a video that discusses how climate feedbacks influence global warming.
This NASA video provides a nice overview of Earth's water cycle from the perspective of looking at Earth from space.
