Good idea. power. 地球上的水是怎么来的呢？小朋友，地球上的水经历了一段十分漫长又奇妙的旅程。在数十亿年前地球刚刚诞生时，星球内部活动十分剧烈，火山持续喷发，释放出大量温热的水蒸气飘荡在天空中。除此之外，来自宇宙的彗星、小行星也携带着冰晶降临地球，为这片土地带来了珍贵的水分。飘散在天空中的水蒸气遇到高空的冷空气后，慢慢凝结成无数小水滴，化作雨水纷纷降落。经过亿万年的积累，雨水四处汇聚，慢慢形成了辽阔的海洋，清澈的湖泊，蜿蜒的江河，就连地下也储存了丰富的地下水，除此之外，大自然还有神奇的水循环，地表的水被太阳照射，蒸发成水汽，飘上天空，形成云朵，再次化作雨水落下，源源不断补充水资源，让地球一直拥有充足的水源，你是不是也觉得大自然的造物本领格外神奇呢？ 你有没有想过一个问题，地球为什么叫地球？明明70%的表面都是水，应该叫水球才对。更奇怪的是这些水到底是从哪儿来的？你看离太阳近的水星没水，离太阳远的火星也没水，邻居月球干的像骨头渣，偏偏地球存了14亿立方公里的水，够把整个美国淹没150公里深。按常理，地球不应该有水。46亿年前，地球刚形成时就是个滚烫的火球，表面温度超过1200摄氏度，连岩石都融化了，水一秒钟就被蒸发到太空那现在这些水谁送来的？第一个嫌疑人，彗星彗星被称为脏雪球，核心就是冰河尘埃，一颗普通彗星含水量相当于一个贝加尔湖。39亿年前，太阳系经历了一场cosmic的暴力拆迁，小行星和彗星疯狂撞击内行星，地球被砸了几十亿年。如果那时候彗星把水送来了，但破案了，科学家测了哈雷彗星的水，发现它的氘氢比例是地球海水的两倍低，盐位对不上，彗星最多只能解释地球10%的水。第二个嫌疑人小行星，准确说是探测球粒陨石，一种黑色的富含粘土矿物的太空岩石。这类陨石的含水量高达20%，关键是它的青铜位数比例和地球海水一模一样，就像水里有DMA完全匹配计算表明，只要地球质量的1%到2%来自这类小行星，今天所有的海洋、湖泊、河流就全齐了。这个理论叫外援说水是太空送来的快递。但问题还没完，你有没有想过另一种可能，谁本来就在地球肚子里？2002年一个颠覆性的发现，地幔深处有一种蓝色岩石，叫尖晶橄榄石。它不含液态水，但每100万个分子里就能抓3000个氢原子和氧原子。整个地幔如果只释放1%，就够填满所有海洋。4份证据，火山喷发时喷出来的气体里，水蒸气占60%以上。这些水不是从地表带下去的，是从地幔自己吐出来的这叫内源说地球是自己产的矿泉水，所以到底哪不对？答案是两个都对。最新研究认为，地球的水大约30%来自小行星的外援，70%来自地幔的内源。早期地幔一边冷却一边试水，原始海洋慢慢形成。后期小行星和彗星又来补了一道，把水加到了今天的量。换句话说，地球的水是自产加快递。所以当你下次喝一口水，看一片海，淋一场雨，你可以告诉别人，这滴水可能在地幔里被锁了四十余年，可能跟着小行星穿越了整个太阳系，可能见证过恐龙和它，也可能变成过一片雪花，地球上所有的水都是时间旅行者，而你喝下的每一口都是46亿年的故事。我是业余科普，关注我，每天满足你的好奇心。
