Fresh rainwater Rain is a form of precipitation. When air becomes saturated with water vapor, the water precipitates out; that is, it condenses on tiny dust particles and falls to the ground in the form of droplets. The water vapor in the air got there in the first place because it evaporated, primarily from the world's oceans and seas. But when saltwater evaporates, the salt dissolved in the water is left behind, which is why rainwater is not salty.
Edit: Not exactly true. SOME salt DOES evaporate (it takes a higher temperature than H2O), so rain water IS a little salty, just not so much that a person can taste it.
Because only pure water can evaporate. Salt cannot evaporate. That is the reason why. Edit: Not exactly true. SOME salt DOES evaporate (it takes a higher temperature than H2O), so rain water IS salty, just not so much that a person can taste it.
Rain, or atmorspheric water vapor is made of just water molecules, not anything that is in the original solution. If you boil salt water the salt remains in the pan because it is too heavy to vaporize.
Salt doesn't evaporate
the salt in the sea water cannot evaporate which therefore means that, only normal water gets evaporated and turned into rain. that is why ran is not salty.
Rainwater is not salty because the only thing being evaporated from the salty oceans it the water, which becomes water vapor. When it finally goes back to being a liquid, the water falls to earth as pure water with no salt.
The reason is because salt doesn't evaporate. You have to picture the water cycle: precipitation, evaporation, and condensation. When water evaporates into the atmosphere, only the water evaporates. So when ocean water evaporates, for instance, only the water becomes vapor. The salt stays a solid, and remains in the ocean.
Due to the process of evaporation, the salt is left behind when the water from oceans evaporate and then reform into rain drops in the atmosphere.
because the water from the sea is evaporated, therefore the salt is separated from the water :)
Because rainwater is fresh water, even if you evaporate saltwater the condensed evaporated water will be fresh.
In the water cycle, water evaporates from oceans and leaves anything that was dissolved in it in the sea. That includes salt. When the water leaves the oceans as it becomes a gas, it leaves as pure water. All the things that were in soluition in it remain behind. Then when that water in the air hits a cold front, condenses and precipitatates out as rain, it's just "fresh water" coming down. The salt is still back in the ocean.
What else can I help you with?
How is the sea salty?
The sea is salty because over billions of years, rain and rivers have washed mineral salts from rocks and soil into the ocean. These dissolved salts, such as sodium and chloride, accumulate in the ocean, making it salty.
Why is the water at the beach salty?
It is salty because the river water heads in it and turns it salty. Animals also make it salty because of their bodies.
Does rain from a tropical storm continue to be salty inland?
No, the rainwater from a tropical storm does not retain its saltiness once it has evaporated and formed clouds. By the time the rain falls inland, it is typically fresh water because the salt is left behind during the evaporation process.
What percantage of the water is salty?
92% of the water is salty.
What type of water is more dense cold salty or warm less salty water?
Cold salty water will be the most dense.
How does the rain affect the salinity of the ocean?
It makes it less salty because rain isn't salty.
Why aren't raindrops salty?
because the sun ONLY evaporates FRESH water so rain drops are NOT salty.
Why sea water is salty than rain water?
sea beds have salt producing mines.
Rain that falls does not taste salty?
You're right, it doesn't. Rain is water that has evaporated and then condensed. Evaporation means that things like salts will be left behind.
If most water evaporates from our salt water oceans why are not rain drops salty?
Salt is not evaporated with water.
Why does the least salty water exist close to ocean surface?
Rain falling on the surface would slightly alter the saline content, at least temporarily. Also, very salty water is denser, so would allow less dense rain water to float near the surface.
How is the sea salty?
The sea is salty because over billions of years, rain and rivers have washed mineral salts from rocks and soil into the ocean. These dissolved salts, such as sodium and chloride, accumulate in the ocean, making it salty.
Why is the lake salty?
The short answer is it's the salt. But I think what you're really asking is how did it get so salty. As fresh water flows through the continents, it picks up salt from the minerals. Then that is dumped into the ocean basin when the water gets to the sea. The water evaporates and returns as rain water, but the minerals stay behind. So after a long time, you get an accumulation of salt in the ocean.
What happens to the denser cold and salty ocean waters?
that the waters evaperate aand the salt that is in it just stay there and more what comes by rain
How is fresh water not salty?
It is the definition of fresh water. Fresh water comes from rain and is pure water, until it reaches the sea which is full of salt.
Why are the oceans meant to be salty?
The oceans are now "meant" to be salty they just are salty. The reason is that when rain falls on the land it disolves some of the chemicals in the soil and the rocks, water then flows into rivers and eventually the seas and the oceans, still catrrying its loads of dissolved chemicals which tend to be nitrates and chlorides because both are soluable, the nirtates get used up by marine vegetation but the chlorides (salts) remain in the water, hence the oceans and the seas are salty.
When is salt water made?
The oceans and seas have been salty for a very long time. As soon as rain began, it would rain on land and the water would dissolve salt from the earth which would run back to the sea. Then sea water would evaporate leaving the salt, and creating more rain. This process repeated itself over eons of time, making the oceans salty. Hydrothermal vents and volcanoes below the surface of the ocean also contribute salt.
