Explore water vapor in the air in part two of the water cycle series. This second part of our series on the water cycle illustrates the way in which evaporation and winds combine to move water from the ocean to the land.

The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. This animation shows fluctuations in the cryosphere.

Ocean circulation plays a key role in distributing solar energy and maintaining climate, by moving heat from Earth's equator to the poles. Aquarius salinity data, combined with data from other sensors, will give us a clearer picture of how the ocean works

Earths climate is changing at an unprecedented rate, and as our home planet warms, so does the ocean. Warming waters have big consequences for phytoplankton and for the planet.
