大學英語作文300字 篇2如果我們分析海水的鹽度，會發現地區間只有輕微的變化，然而有些小的變化是重要的。 導致海洋的鹽度變化的基本過程有三個。
其中之一是通過蒸發的方式即把液態水轉化為水蒸氣來減少海洋中的水分。這樣由於鹽留了下來，所以鹽度增大。
當然，如果這種方式走向極端，將會餘下白色的鹽晶體。 與蒸發相反的是降水，如降雨，由此水被加入海中，海水被稀釋，從而鹽度降低。 這種情形會發生在大量降雨的地區，或江河入海岸處。 因此，鹽度通過蒸發減少水分而上升或通過降水或徑流增加淡水成分而下降。
一般來說，在陽光很強烈的熱帶地區，海水的鹽度略高於世界上其它沒有熱帶那樣多的蒸發的地區。 同理，在江河稀釋海水的海岸地帶，海水鹽度略低於其它海區。
第三個可以變更鹽度的過程與海洋中冰的形成和融化有關。 海水凍結時，溶於其中的物質被留了下來。 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。 當然，當冰融化的時候，會降低周圍水中的鹽度。 在南極洲邊緣的威德爾海中，結冰過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現。

大學英語作文300字 篇4as the water frothed,
and the sun did go,
the dark brought forth a tear,
i sat up high,
upon my rock,
no one would see me here.
when all is lost,
i stare alas,
and listen to the oceans prayer,
you must listen close,
her words are soft,
yet, they are always there.
she knows how you pain,
when the light is gone,
and the dark tells you lies,
she says to you,
that no matter what,
the sun will always rise.
and when it comes,
it pierces the horizon,
showing the dark no fear,
for the light comes every day,
each morning,
to dry up that fallen tear.
