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。另外在自然界中，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1360000000立方公里。海洋占了1320000000立方公里（或97.2%）；冰川和冰盖占了25000000立方公里（或1.8%）；地下水占了13000000立方公里（或者0.9%）；湖泊、内陆海，和河里的淡水占了250000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13000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。

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。

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。
