水循环是指水由地球不同的地方透过吸收太阳以来的能量转变存在的模式到地球中另一些地方，例如：地面的水份被太阳蒸发成为空气中的水蒸汽。而水在地球的存在模式包括有固态、液态和气态。而地球中的水多数存在于大气层中、地面、地底、湖泊、河流及海洋中。水会透过一些物理作用，例如：蒸发、降水、渗透、表面的流动和表底下流动等，由一个地方移动至另一个地方。如水由河川流动至海洋。

水循环是指水由地球不同的地方透过吸收太阳以来的能量转变存在的模式到地球中另一些地方，例如：地面的水份被太阳蒸发成为空气中的水蒸汽。而水在地球的存在模式包括有固态、液态和气态。而地球中的水多数存在于大气层中、地面、地底、湖泊、河流及海洋中。水会透过一些物理作用，例如：蒸发、降水、渗透、表面的流动和表底下流动等，由一个地方移动至另一个地方。如水由河川流动至海洋。
水循环的主要作用表现在三个方面：①水是所有营养物质的介质，营养物质的循环和水循化不可分割地联系在一起；②水对物质是很好的溶剂，在生态系统中起着能量传递和利用的作用；③水是地质变化的动因之一，一个地方矿质元素的流失，而另一个地方矿质元素的沉积往往要通过水循环来完成。
水的大循环和小循环
水循环分为大循环和小循环。从海洋蒸发出来的水蒸气，被气流带到陆地上空，凝结为雨、雪、雹等落到地面，一部分被蒸发返回大气，其余部分成为地面径流或地下径流等，最终回归海洋。这种海洋和陆地之间水的往复运动过程，称为水的大循环。仅在局部地区(陆地或海洋)进行的水循环称为水的小循环。环境中水的循环是大、小循环交织在一起的，并在全球范围内和在地球上各个地区内不停地进行着。
水循环的形成和影响因素
形成水循环的内因是水在通常环境条件下气态、液态、固态易于转化的特性，外因是太阳辐射和重力作用，为水循环提供了水的物理状态变化和运动的能量。地球上的水分布广泛，贮量巨大，是水循环的物质基础。由于地球上太阳辐射的强度不均匀，不同地区的水循环的情况也就不相同。如在赤道地区太阳辐射强度大，降水量一般比中纬地区多，尤其比高纬地区多。
影响水循环的因素很多。自然因素主要有气象条件(大气环流、风向、风速、温度、湿度等)和地理条件(地形、地质、土壤、植被等)。人为因素对水循环也有直接或间接的影响。
Water from the water cycle is different from the Earth through absorption of solar energy has been changing the model to Earth in some other places, such as: ground water by solar evaporation of a water vapor in the air. The presence of water on Earth models including solid, liquid and gaseous. While the majority of water in the Earth exists in the atmosphere, ground, underground, lakes, rivers and oceans. Some water through physical action, such as: evaporation, precipitation, infiltration, surface flows and flows under the table, from one place to another mobile. If water flows from the river to ocean.
The main role of the water cycle in three respects: 1 Water is the medium of all nutrients, nutrient cycling and water shabby inextricably linked; ② water right is a very good solvent substances in the ecosystem, an energy transfer and use of the role; ③ water is the result of geological changes one of the elements of a local mineral loss, and another deposition of mineral elements often through the water cycle to complete.
The water circulation and circulation
The water cycle is divided into circulation and circulation. By evaporation from the ocean, water vapor, was taken to the air over land, condensation for rain, snow, hail, fell on the ground, was part of evaporation to the atmosphere, as the rest of the surface runoff or groundwater runoff, the ultimate reunification Ocean. Such between marine and terrestrial water reciprocating movement, known as the water cycle. Only in a local area (land or sea) of the water cycle as water circulation. The environment in the water cycle is the big dog intertwined, and at the global level and in all areas on the planet constantly conducting.
The formation of the water cycle and impact factors
Formation of the water cycle internal water under normal conditions gaseous, liquid, solid easily into the characteristics of external radiation and the solar gravity, the water cycle to provide water for the physical changes and movement of energy. Earth's water is widely distributed, huge reserves, is the material basis of the water cycle. As on Earth uneven intensity of solar radiation, different regions of the water cycle is also not the same. In equatorial regions such as solar radiation intensity, precipitation than normal in latitudes, especially more than the high latitude regions.
Many factors affect the water cycle. Natural factors main meteorological conditions (atmospheric circulation, wind direction, wind speed, temperature, humidity, etc.) and geographic conditions (topography, geology, soil, vegetation, etc.). Human factors on the water cycle has a direct or indirect impact.
