Salt Lakes of the World
Salt Lakes of the World The most famous salt lake in the world is the Dead Sea, in the Middle Eart. Water is lost into the air because of the heat of the sun, and the salt stays in the lake. It is also very lowlying, at around 395 metres below sea level. However, it is not the saltiest lake in the world. The Great Salt Lake in the USA, with 270 parts of salt per thousand, is even saltier. The water of the Dead Sea contains about 250 parts of salt to every thousand parts of water, or 25% by weight. It is so salty that it is difficult to swim or dive, as your body floats on the surface. What has made this lake so salty? The minerals are partly supplied by hundreds of natural springs which flow into the Dead Sea, and partly by the River Jordan. It is called the Dead Sea because very few things can live in such salty water. There is very little rain here, merely 60mm in a year on average. The minerals stay in the lake, because there is no river flowing out of the lake. 此文描述了世界兩大鹽湖形成的原因，以及鹽湖中所含的成份，是一篇非常好的背景材料，可供讀者在寫有關(guān)文章時(shí)引用。 世界上的咸水湖 世界上最有名的咸水湖是中東的死海。由于太陽酷熱，水變成了水蒸汽，而鹽分仍留在湖中。這里的地勢(shì)也很低，約低于海平面395米。然而死海并不是世界上最咸的咸水湖。美國大鹽湖的水還要咸一些，每千份水中含有270份鹽。 死海中的水每千份水里含有250份鹽，或者說按重量計(jì)占25％。湖水太咸了，很難游泳或潛水，因?yàn)槟愕纳眢w會(huì)浮在水面上。是什么東西使得湖水這樣咸呢?是各種礦物質(zhì)。它的部分來自眾多的流入死海的天然泉水，部分來自約旦河。這個(gè)咸水湖之所以稱作死海，是因?yàn)樵谶@樣咸的水中幾乎沒有什么東西能夠生存。這兒雨水極少，平均每年只有60毫米。因?yàn)楹荒芡ㄟ^江河流出去，所以礦物質(zhì)就沉積在湖中了。
