Water has a regulatory role on the climate. The water vapor in the atmosphere to block the Earth's radiation levels 60 percent to protect the Earth will not be cooling. Marine and terrestrial water in the summer and the accumulation of heat-absorbing, so that the temperature is not too high; in the winter can slowly release heat, so that the temperature not too low. Marine and surface evaporation of water to form a cloud in the sky, the clouds of water through the precipitation turned to rain down, then turned into snow in the winter. Drop in on the surface of the water to seep into underground water formation; out in formation from the water to form a spring, through a stream, river into the sea. A water cycle. Rain and snow precipitation, and other activities form an important climate. In the temperate monsoon climate, the monsoon brought abundant moisture to form a distinct wet and dry autumn. In addition, in nature, due to different climatic conditions, water will be to hail, fog, dew and frost, and other emerging patterns and effects of climate and human activities. 71% of the Earth's surface covered by water from the air, the earth was a blue pla. Water erosion of rock soil, river erosion, sediment transport, and create a plain, changes in surface patterns. Earth surface water constitute the hydrosphere, including the oceans, rivers, lakes, swamps, glaciers, snow and groundwater in the atmosphere and water. As the water into the ocean with a certain amount of salt, together with the accumulation of annual evaporation and the role of the sea and ocean water is salt water, can not be directly consumed. Some of the lake water is saline with. The world's largest body of water in the Pacific. Great Lakes of North America is the largest freshwater system. Eurasia on the Caspian Sea is the largest salater lake. Shui volume of the earth about 1 360 000 000 cubic kilometers. Marine accounted for 1 320 000 000 cubic kilometers (or 97.2%); glaciers and ice caps account for 25 000 000 cubic kilometers (or 1.8%); groundwater accounts for 13 000 000 cubic kilometers (or 0.9%); lakes, inland Sea, river and fresh water accounts for 250 000 cubic kilometers (or 0.02%); water vapor in the atmosphere at any known time has a market share of 13 000 cubic kilometers (or .001 percent). Life on Earth was first emerging in the water. Water is the life of all an important part of the body. In the body of water accounted for 70%; and jellyfish in the water is 98%. Life in the water with a large number of aquatic vegetation, and other aquatic ani *** s. Water is conducive to chemical reactions in the body, the body also has played in the transport of biological material. The water temperature to maintain the stability of the ani *** plays an important role 水对气候具有调节作用。
大气中的水汽能阻挡地球辐射量的60%，保护地球不致冷却。海洋和陆地水体在夏季能吸收和积累热量，使气温不致过高；在冬季则能缓慢地释放热量，使气温不致过低。
海洋和地表中的水蒸发到天空中形成了云，云中的水通过降水落下来变成雨，冬天则变成雪。落于地表上的水渗入地下形成地下水；地下水又从地层里冒出来，形成泉水，经过小溪、江河汇入大海。
形成一个水循环。 雨雪等降水活动对气候形成重要的影响。
在温带季风性气候中，季风带来了丰富的水气，形成明显的干湿两季。 此外，在自然界中，由于不同的气候条件，水还会以冰雹、雾、露水、霜等形态出现并影响气候和人类的活动。
地球表面有71%被水覆盖，从空中来看，地球是个蓝色的星球。水侵蚀岩石土壤，冲淤河道，搬运泥沙，营造平原，改变地表形态。
地球表层水体构成了水圈，包括海洋、河流、湖泊、沼泽、冰川、积雪、地下水和大气中的水。由于注入海洋的水带有一定的盐分，加上常年的积累和蒸发作用，海和大洋里的水都是咸水，不能被直接饮用。
某些湖泊的水也是含盐水。世界上最大的水体是太平洋。
北美的五大湖是最大的淡水水系。欧亚大陆上的里海是最大的咸水湖。
地球上水的体积大约有 1 360 000 000 立方公里。海洋占了1 320 000 000立方公里（或97.2%）；冰川和冰盖占了25 000 000立方公里（或1.8%）；地下水占了13 000 000立方公里（或者0.9%）；湖泊、内陆海，和河里的淡水占了250 000 立方公里（或0.02%）；大气中的水蒸气在任何已知的时候都占了13 000立方公里（或0.001%）。
地球上的生命最初是在水中出现的。水是所有生命体的重要组成部分。
人体中水占70%；而水母中98%都是水。水中生活着大量的水生植被等水生生物。
水有利于体内化学反应的进行，在生物体内还起到运输物质的作用。 水对于维持生物体温度的稳定起很大作用。
3. 一篇关于水的作用的英语作文
Water is essential to living things. For instance, if there is no enough water in a human body, a person may feel unfortable or get sick easily. To make matters worse, one may die of thirst. Similarly, plants may wither or die for lack of water. It is apparent that all living things need water to keep alive.
Judging from the importance of water, we should know how to conserve water. The first thing is to stop polluting water because what we really need is clean water. At the same time, be sure to turn off the faucet immediately after using water. And we should make efficient use of water to avoid wasting it. One way is to recycle as much water as possible. To sum up, we should economize on water so as to maintain the abundance of water, which is an indispensable element of life.
水对生存事是根本的。 例如，如果没有在人体的足够的水，人也许感到难受或容易地病。 要使事态更坏，一个也许死于干渴。 同样，植物也许凋枯或死因缺乏水。 是明显的所有生存事需要水保持活。 从水判断的重要性，我们应该会保存水。 第一件事是停止污染水，因为什么我们真正地需要是清水。 同时，请务必关闭在使用水之后的龙头。 并且我们应该做高效率的用途水避免浪费它。 一种方式将回收同样多水尽可能。 要总结，我们在水应该节约以便维护水丰盈，是生活的一个不可缺少的元素。

Since the ancient times, fish have been living in the water, so fish and water has always been a good friend.
Spring girl wearing green clothes came quietly, head fish are floating on the sea surface, watching the spring for the "movie." There is a *** all fish to speak of: "How beautiful ah!" The fish have all said: "yes ah!"
After listening to their conversation stream, very angry and said: "Well, since you view it like to land up ah! My house you can not tolerate the" eyed. "In this way, they are the busy noisy.
The next day, the fish have a good clean up their own "baggage", ready to start it! When led poisonivy ready to say "start", the seaweed they have to persuade: "Do not go, ah, you are the fish, is the water of the animals, if the land up, it would mean the loss of life ah!" But fish in the door not only did not listen to advice, but also scolded those who were ignorant of seagrass. River could not help but feel anger at last, stern voice said: "Do not control them, let them go by!"
To the land, the state of the door at first the fish is also very good, but the fish are very thirsty, his voice all *** oke, and all of a sudden, almost dying fish and the river it? At the time of the terrible quiet during the day is not to mention. River began to regret it.
One day, a kindly old lady came to the riverside walk and saw a lot of "fish", but not yet dead, on the one hand and put them back into a river. However, back to the river, and only 10 others have died. No dead fish were very sad, but also be aware of her own errors, where the river ran an apology. Stream it? Apologize to them.

Chemical position of the water to see if the percentage by mass, containing 11.11% hydrogen and 88.89% oxygen. If you press the volume point of view, there are o hydrogen one oxygen. Separate existence of water molecules is called a single water molecules, water molecules could form the pairs of the association of water molecules, Sanshui molecules. Features include a high boiling point of water, evaporation heat large, high heat capacity, abnormal swelling, a good solvent, such as the association can continue to occur.Water with other substances, when heated volume increases, density decreases. Pure water at zero degrees Celsius when the density of 999.87 kilograms / cubic meter, the density of water at the boiling point of 958.38 kilograms / cubic meters, density decreased 4%.Under normal atmospheric pressure, water freezes, the volume suddenly increased around 11%. When the ice melts the volume suddenly reduced. According to scientists, observation, in a closed space, water is frozen, and change water as ice, the volume increase in the pressure generated by atmospheric pressure up to 2500. This feature of nature and industry are important. Repeated freeze-thaw rock fractures when the fracture is gradually increasing is this truth. Buried plastic pipe for water antifreeze bad, generally require a certain depth (greater than the frozen soil layer depth).The freezing temperature of water decreases with increasing pressure. About every 130 increase in atmospheric pressure, the water freezing temperature reduced by 1 degree Celsius. This feature makes the ocean water, deep water will not freeze.The boiling point of water and pressure into a linear relationship beeen changes. Boiling point increases with pressure increase.In addition to heat capacity of water than the hydrogen and a *** all heat capacity of aluminum, the heat capacity than any other substances are higher. Heat transfer of water is *** aller than the other liquids. Because of this characteristic, the natural body of water, when frozen slowly, thickening of the ice-class experience, even in its frozen surface of the water a long time, the river may still be in the depths of liquid water in the characteristics of the underwater life of great significance. This feature of water for irrigation is also to guide meaningful, such as conducting winter irrigation can increase ground temperature, to prevent winter crops by the low-temperature damage.水的化学成分如果按质量百分比看，含有11.11%的氢和88.89%的氧。
如果按体积来看，则有两份氢一份氧。单独存在的水分子叫作单水分子，水分子发生缔合可构成双水分子、三水分子等。
水的特性包括沸点高、蒸发热大、热容高、反常膨胀、良好溶剂、能不断发生缔合等。水同其它物质一样，受热时体积增大，密度减小。
纯水在摄氏零度时密度为999.87千克/立方米，在沸点时水的密度为958.38千克/立方米，密度减小4%。在正常大气压下，水结冰时，体积突然增大11%左右。
冰融化时体积又突然减小。据科学家观测，在封闭空间中，水在冻结时，变水为冰，体积增加所产生的压力可达2500个大气压力。
这一特性对自然界和工业有重要意义。岩石裂隙在反复融冻时裂隙逐渐增大就是这个道理。
地埋输水塑料管为防冻坏，一般要求一定的埋深（大于冻土层深度）。水的冻结温度随压力的增大而降低。
大约每升高130个大气压，水的冻结温度降低1摄氏度。水的这种特性使大洋深的水不会冻结。
水的沸点与压力成直线变化关系。沸点随压力的增加而升高。
水的热容量除了比氢和铝的热容量小之外，比其它物质的热容量都高。水的传热性则比其它液体小。
由于这一特性，天然水体封冻时冰体会级慢地增厚，即使在水面长其封冻时，河流深处可能仍然中液体，水的这种特性对水下生命有重要意义。水的这一特性对指导灌溉也有意义，如进行冬灌能提高地温，防止越冬作物受低温冻害。
