Warren, you're not as informed as you think you are. http://landresources.montana.edu/LRE...pic%20B2_Part1 _Solution_Chemistry_Web.pdf According to the site above, from University of Montana, the composition of rainfall is nearly identical to seawater with some additional molecules picked up in the atmosphere. Let's see now: 1) People drink rain water, especially on ocean islands where there is no other fresh water, are very healthy. 2) People who drink sea water die. and you claim that they are the same.

I hope you don't try to drink sea water. The methods by which it can be assessed that rainwater is evaporative from the sea measured for it's isotopic signature & ionic proportionality does not mean rainfall that is the "same" as the sea for salt content. When by mass ratio it can be proven that sodium & chloride ions in groundwater are "the same as seawater" this means whatever the salt load (whether barely detectible or extremely great) originated in the ocean vs originating in mineral dissolution or man-caused pollutants. It does NOT mean the groundwater or the rainfall is sal****er. It just doesn't mean that. As sensible to believe being that signatures & proportionality "the same as seawater" means rainfall is teaming with plankton & jellyfish. Salinity in soil DECREASES in areas of highest rainfall. If rain were salty the opposite would be true, & much of the world would drop dead because rainwater would be unfit to drink. Rainfall even lowers the salinity in tidal areas of the ocean itself. In the Ariake Sea for a studied example, salinity for most of the year is a fairly constant 25-26%. During the rainy monsoon season salinity drops to 15% [H. Koike, University of Tokkyo Bulletin 18, 1980]. So too mangrove swamps become decreasingly salinized when deluted during rainy seasons. If the "sameness" of rainwater & seawater was defined by their salt content, tidal environments would not have lowered salinity during heavy rainfall, & the land surface would become so salinized, within a year or two the earth would no longer be habitable my man. What sodium does find its way into rainfall is generally assumed to be of ocean origin. It is such an inconsequential component that rainfall is NEVER given as one of the causes of inland salinization. It's beyond comprehension that even one person really believes rainfall has the same salt content as the sea. Such belief is explicable only if scientific knowledge, ability to reason, or even the ability to draw personal conclusions after opening one's mouth in a rainstorm, are fast slipping away from an increasingly imbecilic population. And so the thread gets increasingly stupid from assertions that rhododendrons are planted as salt air windbreaks, that the Atlantic ocean dumps sal****er 300 miles inland from rainclouds & storms, & that sodium mass ratio statistics for FRESHWATER somehow prove that freshwater is in reality sal****er.

Ah, a change of heart from your earlier mistake when you claimed Salt is NOT evaporated into clouds & precipitation NEVER salinizes soils. So that says to you salt evaporates does it? Sodium isotopic signatures are not evidence that freshwater is sal****er, no more than is a fingerprint left on your booze glass proof that the glass is actually your finger, or a crime lab's DNA reading from a cigarette butt proof that that cigarettes are people. Here's an elementary school science fact for you: Salt does not evaporate because it is non-volatile. Perhaps you're legitimately not smart enough to tell sal****er from freshwater, but the facts do remain salt does NOT evaporate into clouds & it's loony to persist in your belief that it does. Rainfall does NOT salinize soil as you persist in believing; the facts are the exact opposite of what you eerily want to believe is true. This really simple child's science experiment tends to convince the kiddies: Dissolve precisely 15 ml of salt (about a tablespoon) in a half a cup of water. Set in sun until water evaporates. Weigh salt. From this a very young school child learns that salt does not evaporate or undergo any chemical alteration in water. Alas, I suspect YOUR conclusion would have to be that the 15 ml of crystals left in the cup is dehydrated water concentrate, because the salt evaporated. It's beyond comprehension that even one person really believes rainfall has the same salt content as the sea. Such belief is explicable only if scientific knowledge, ability to reason, or even the ability to draw personal conclusions after opening one's mouth in a rainstorm, are fast slipping away from an increasingly imbecilic population. -paghat the ratgirl -- Get your Paghat the Ratgirl T-Shirt he http://www.paghat.com/giftshop.html "In every country and in every age, the priest has been hostile to liberty.

Janet Baraclough expounded:
(It does salinate soil in Australia, btw..cite already provided) No, it doesn't. What salinates the soil in Australia is too complicated to get into here, it has to do with underground salt deposits, the loss of native cover and the inability of the soil to deal with all the water. The salt is already there, in vast underground stores. See http://news.bbc.co.uk/2/hi/science/nature/3564857.stm for a bit of what's going on. -- Ann, gardening in Zone 6a South of Boston, Massachusetts e-mail address is not checked ****************************** |
