英語(yǔ)作文400字 篇1
如果我們分析海水的鹽度，會(huì)發(fā)現(xiàn)地區(qū)間只有輕微的變化，然而有些小的變化是重要的。 導(dǎo)致海洋的鹽度變化的基本過(guò)程有三個(gè)。
其中之一是通過(guò)蒸發(fā)的方式即把液態(tài)水轉(zhuǎn)化為水蒸氣來(lái)減少海洋中的水分。這樣由于鹽留了下來(lái)，所以鹽度增大。
當(dāng)然，如果這種方式走向極端，將會(huì)余下白色的'鹽晶體。 與蒸發(fā)相反的是降水，如降雨，由此水被加入海中，海水被稀釋?zhuān)瑥亩}度降低。 這種情形會(huì)發(fā)生在大量降雨的地區(qū)，或江河入海岸處。 因此，鹽度通過(guò)蒸發(fā)減少水分而上升或通過(guò)降水或徑流增加淡水成分而下降。
一般來(lái)說(shuō)，在陽(yáng)光很強(qiáng)烈的熱帶地區(qū)，海水的鹽度略高于世界上其它沒(méi)有熱帶那樣多的蒸發(fā)的地區(qū)。 同理，在江河稀釋海水的海岸地帶，海水鹽度略低于其它海區(qū)。
第三個(gè)可以變更鹽度的過(guò)程與海洋中冰的形成和融化有關(guān)。 海水凍結(jié)時(shí)，溶于其中的物質(zhì)被留了下來(lái)。 這樣，在新形成的海水冰面的正下方的海水比在冰形成之前有更高的鹽度。 當(dāng)然，當(dāng)冰融化的時(shí)候，會(huì)降低周?chē)械柠}度。 在南極洲邊緣的威德?tīng)柡Ｖ�，結(jié)冰過(guò)程增加低溫海水的鹽度，從而形成了濃度最大的海水。 這些大密度的海水下沉，可以在世界海洋的深水域發(fā)現(xiàn)。

我就要過(guò)一個(gè)忙綠的周末了!星期六的時(shí)候我會(huì)騎車(chē)去拜訪(fǎng)我的朋友。因?yàn)槲乙呀?jīng)很久沒(méi)見(jiàn)他們了。之后，我會(huì)走路去書(shū)店。我打算在書(shū)店里看很多的`書(shū)。星期天早上，我打算去散散步。然后，下午的時(shí)候我會(huì)和媽媽去買(mǎi)東西。之后，我們晚上打算一起看電視。那肯定很有趣!你呢?周末你打算做什么呢?
