阅读下文完成以下各题奇特的海水咸度①海洋奔腾不息海水深邃莫测但口渴者却不敢问津因为它有着又成又涩的苦味②现在科学家已经测出海水有3%左右是食盐可别小看这区区的3%如果把它全部提炼出来平铺在陆地上陆地的高度将要增加120多米这是多么巨大的数量啊!③除了食盐外海洋中还含有100万亿吨镁600万亿吨钾88万亿吨铜58亿吨镍40亿吨铀这样看来海洋又是矿物的大仓库④其实海水并不是一开始就充满盐分它最初和江河湖水一样也是含盐量很少的淡水但地球的水总是在不停地运动不停地循环有人曾做过这样一项测试单单每年从海湾表面蒸发掉的水分就达到1亿吨这么多的水又会变成雨降到陆地的每个角落它们潺潺而流不断地冲刷岩石冲刷土壤把岩石和土壤中的可溶性物质带进江河之中而这些物质绝大部分都是各种盐类盐分随着水流进入江河而江河之水最后又都回归大海蒸发掉的水分再次回到自己的海洋老家但它却带来了很多陆地上的盐分⑤就这样海洋源源不断地从陆地上得到微量物质成了所有溶解盐类的收容所可是在海水的蒸发过程中进入海洋的盐分却不能随水蒸气升空只得滞留在大海洋之中⑥如此周而复始日积月累海洋中的盐类物质越积越多海水也就理所当然地变得越来越咸了当然这是一个极为缓慢的过程可是经过几百万年甚至更久的年代积累起来的盐分也就十分可观了⑦海水中既然已经含有那么多盐分而且以后每年还要从陆地上带回大约30亿吨的可溶性物质海水会不会永无止境地越变越成会不会把所有的海洋生物都咸死⑧这种担心完全是合情合理的如果海洋没有减少自身盐分的方法结果肯定会这样但科学家在研究中发现海洋有各种能降低海水含盐度的奇妙方法⑨随着陆地可溶性物质不断进入海洋当达到一定的浓度后便会互相结合成不溶解性化合物沉入到海洋的底部这个过程就像明矾能沉积水的杂质那样使浑浊的水质变清除此以外许多物质还会被海洋生物的细胞所吸收等生物体死去后便随尸体沉入到海底以上这些途径都能大大降低海水中的含盐浓度⑩当台风季节降临时狂风巨浪常把海水卷到陆地上溶解的盐分也随海水上岸散布在沿海陆地尤其在漫长的历史变迁年代中有些海洋的海湾地带由于地壳的升高而与海洋隔断于是这部分的海水逐渐被蒸发掉留下大量的溶解性盐类物质这也是盐分回归陆地的一种方式例如现在陆地上某些开采食盐的盐矿就是这类干涸掉的小块海洋的残迹海洋有哪些能降低海水含盐度的方法请用简练的语言加以概括

阅读下文完成以下各题奇特的海水咸度①海洋奔腾不息海水深邃莫测但口渴者却不敢问津因为它有着又成又涩的苦味②现在科学家已经测出海水有3%左右是食盐可别小看这区区的3%如果把它全部提炼出来平铺在陆地上陆地的高度将要增加120多米这是多么巨大的数量啊!③除了食盐外海洋中还含有100万亿吨镁600万亿吨钾88万亿吨铜58亿吨镍40亿吨铀这样看来海洋又是矿物的大仓库④其实海水并不是一开始就充满盐分它最初和江河湖水一样也是含盐量很少的淡水但地球的水总是在不停地运动不停地循环有人曾做过这样一项测试单单每年从海湾表面蒸发掉的水分就达到1亿吨这么多的水又会变成雨降到陆地的每个角落它们潺潺而流不断地冲刷岩石冲刷土壤把岩石和土壤中的可溶性物质带进江河之中而这些物质绝大部分都是各种盐类盐分随着水流进入江河而江河之水最后又都回归大海蒸发掉的水分再次回到自己的海洋老家但它却带来了很多陆地上的盐分⑤就这样海洋源源不断地从陆地上得到微量物质成了所有溶解盐类的收容所可是在海水的蒸发过程中进入海洋的盐分却不能随水蒸气升空只得滞留在大海洋之中⑥如此周而复始日积月累海洋中的盐类物质越积越多海水也就理所当然地变得越来越咸了当然这是一个极为缓慢的过程可是经过几百万年甚至更久的年代积累起来的盐分也就十分可观了⑦海水中既然已经含有那么多盐分而且以后每年还要从陆地上带回大约30亿吨的可溶性物质海水会不会永无止境地越变越成会不会把所有的海洋生物都咸死⑧这种担心完全是合情合理的如果海洋没有减少自身盐分的方法结果肯定会这样但科学家在研究中发现海洋有各种能降低海水含盐度的奇妙方法⑨随着陆地可溶性物质不断进入海洋当达到一定的浓度后便会互相结合成不溶解性化合物沉入到海洋的底部这个过程就像明矾能沉积水的杂质那样使浑浊的水质变清除此以外许多物质还会被海洋生物的细胞所吸收等生物体死去后便随尸体沉入到海底以上这些途径都能大大降低海水中的含盐浓度⑩当台风季节降临时狂风巨浪常把海水卷到陆地上溶解的盐分也随海水上岸散布在沿海陆地尤其在漫长的历史变迁年代中有些海洋的海湾地带由于地壳的升高而与海洋隔断于是这部分的海水逐渐被蒸发掉留下大量的溶解性盐类物质这也是盐分回归陆地的一种方式例如现在陆地上某些开采食盐的盐矿就是这类干涸掉的小块海洋的残迹请揣摩文段⑦和文段⑩中加点的词语回答问题①大约一词能否去掉为什么②卷能否换成带或推为什么
