The Earth is 2/3eds covered with water. The Sun and wind evaporate water, mostly ocean water, and clouds form. The clouds are carried over land by wind. When the right atmospheric conditions are met, the water vapor (clouds) condense and it rains. This entire process is solar driven.
The rain supplies us with fresh water and waters the planet. Then it eventually drain into a river or an aquifer and it flows back to the ocean. And the whole process starts over again.
We are drinking and using the same water the people of the Roman Empire did. Sounds gross but it's not. No matter how polluted water becomes, when it evaporates, it’s pure water again.
Here is a lesson on the The Water Cycle:

This is a better lesson on the water cycle but it's off-line right now due to the government shutdown. It should be back on-line soon: http://ga.water.usgs.gov/edu/watercyclee...
This video will help to show water's impact on climate... which is huge.
The Great Global Warming Swindle
The water cycle involves the following stages: precipitation, infiltration, transpiration, evaporation and condensation. The water cycle is the repeated process in which water evaporates from oceans and transpires from plants condensing to form water vapour which eventually turns to clouds that causes precipitation then is infiltrated by the soil. Therefore, the water cycle which is solar driven will affect the amount of rain received, the humidity and temperature of a particular region. These factors contribute to determine the climate and weather.
Water is the main factor in determining out weather, but paradoxically, it is CO2 that ultimately controls changes in the climate. The reference below explains why that is so.
extremely tough point. look with google. just that may help!
explain the water cycle and its relationship to weather ahd climate.
