海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个，其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。

这种情形会发生在大量降雨的地区，或江河入海岸处。因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说，在阳光很

强烈的热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时，溶于其中的物质被留了下来。这样，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盐度。

当然，当冰融化的时候，会降低周围水中的盐度。

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。这些大密度的海水下沉，可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.

冬至英语（优秀作文）

Winter is coming, when it comes to the traditional festival is my favorite, I cannot hide the excitement of the heart. Winter solstice can make dumplings, eating dumplings, it makes me feel the winter solstice is the most happy.

Speak of the winter solstice eat dumplings, there is also a custom! In my hometown - the north of henan province, the winter solstice every family tradition is to make dumplings, eating dumplings. As the saying goes: "the winter solstice misconduct dumplings bowl, frozen off ears is nobodys business."

The custom of the northern winter eat dumplings is due to the memory of "the medical sage" zhang zhongjing winter solstice medicine left. Hungry people eat dumplings, to drink the "remove cold soup", and warm, fever, two ears frostbite ears were cured.

No matter you have the habit of eating dumplings, wish everyone happy winter solstice, happily and family spent together the happy holiday!

冬至就要到了，说到这个我最喜欢的传统节日，我就难掩心里的兴奋。冬至可以包饺子，吃饺子啊，这让我觉得冬至是最快乐的。

一到冬至，我和妈妈就准备好包饺子的材料：一些鲜肉，一些饺子皮。我拿起一张饺子皮放在左手上，右手用筷子挖一点鲜肉，放到饺子皮里去。可是鲜肉好像很活泼，蹦蹦跳跳的，好不容易封上口结果又撑开了……包饺子可真不容易啊!

说起冬至吃饺子，这里面还有一个风俗呢!在我的老家——北方的河南省，到了冬至家家户户的传统习俗就是包饺子、吃饺子。俗话说：“冬至不端饺子碗，冻掉耳朵没人管。”

北方冬季吃饺子的习俗是因纪念“医圣”张仲景冬至舍药留下的。饥寒交迫的人们吃了饺子，喝了“祛寒汤”，浑身暖和，两耳发热，冻伤的耳朵都治好了。

不管大家有没有吃饺子的习惯，都祝愿所有人冬至快乐，开开心心地和家人一起度过这个愉快的节日吧!
