我们常说空气是看不见、摸不着；看不见是真的，但摸不着是假的；我们能感受到风，而风就是流动的`空气形成的，所以空气是摸得着的。空气并不是单一的一种气体，它是由氮气、氧气、二氧化碳等多种气体组成的。其中氮气占78%，氧气占21%、二氧化碳及其他气体共占1%。所有生物（除病毒外）都要进行呼吸，吸入的气体中真正有用的是氧气。那空气中的氧气岂不会多年后用完呢？不会的，因为植物可以吸收二氧化碳进行光合作用产生氧气。
空气中的氮气对生物没有直接作用，但它可以被闪电通过系列反应转化成氮肥，供植物使用。氮气性质不活泼可用来保鲜食品，医疗上可以用液态氮做麻醉剂。二氧化碳的用途也比较多，它可以制成干冰进行人工降雨、还可以用来灭火。空气中的稀有气体大多数可以充入灯管中制成霓虹灯，使夜晚色彩亮丽。
想要了解空气，就得了解大气层。大气层说白了就是地球上厚厚的一层空气。然而大气层并不是想象中那么简单，它分为好几层，每层高度不一样，海拔越高，空气越稀薄。所以卫星或其他航天器一般都会飞到几百千米以上，若飞得底了些，那稀薄的空气会使卫星减速、坠落。
之前说的都是看不见的，接下来会有看得见的。
这些看得见的东西就是空气中的微小颗粒，当然，它们不属于空气，它们只是夹杂在空气中而已。常见的灰尘就是微小颗粒，但灰尘在其中已是“大个头”了，比较小的有“PM10”“PM2.5”等。而“PM2.5”小到可以直接进入你的肺泡！所以也被称为“可吸入颗粒物”。众所周知，这些颗粒对人体是有害的，颗粒越小，在空气中停留的时间越长，对人体的危害也就越大。
了解了这么多后，请为了这生命的必须品多植一颗树，少乘一次车；以便以后还能再次深呼吸而不咳嗽吧！
