Water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again.
The atmospheres of the other terrestrial planets have very little water content, but water vapor is measurable on Venus and Mars. Water is constantly cycled between the atmosphere and surface of Earth. Most water vapor enters our atmosphere by evaporation from surface water and wet soil.Some water vapor also enters our atmosphere from the leaves of plants by a process called transpiration.Water returns to the surface by condensation in the atmosphere and precipitation.Clouds of water droplets form when water vapor condenses in the atmosphere.oisture enters the atmosphere when surface water evaporates, and returns to the surface when the atmospheric water vapor condenses and precipitates.
