Is this true?!?!?!?omg?

Question

That everyday water vapor escapes out of the atmosphere into space?

my science teacher last year was talking about this in class. she said she heard this on national geographic!

now i am scared because of water wasters

Answer 1

omg are you serious thats pretty babyish....

the world aint never gunna run out of water lol

Answer 2

Yes, but new water is being produced in the earth's mantle and released into the atmosphere by volcanoes

Answer 3

Under the sun, sea water becomes water vapors escapes out into the sky. While there is too much water in the air, it produces clouds. Clouds turned into rain.

On the contrarily, the trees in the thick forest, just like the hair on our head, is to protect the earth from the sun.

Answer 4

no! water vapors are trapped on clouds when they go up...  

Answer 5

Nah it'll be fine, just look up the water cycle

People may have to conserve water, but there won't be a time when there's none of it

Answer 6

Yea

Maybe you'll think next time before you take a 3 hour shower...

Or maybe not and we'll all die from thirst (or at least our children will)

Answer 7

It almost certainly does. But, at the same time, tons of water is coming into our planet due to ice asteroids hitting the atmosphere, so I don't think this should be your major concern.

Answer 8

With altitude, the atmosphere temperature sinks all the way up to the tropopause at about 12 km above. Above that, in the stratosphere, mesosphere, etc, the temperature rises then sinks again.

So, clouds are never going over the tropopause ... almost. Sometimes, some ice particles move above it and above and above and ... disappear into space. That is true. But ....

We are constantly being bombarded by small objects travelling in space. We call it shooting stars. Those are mostly "dirty ice," i.e. water mixed with various minerals that make the comets.

I read that we estimate the total amount of such 'water' that has reached earth since its existance to be roughly equal to all the water from all the oceans.

Some, water comes in and water goes out. It looks like, so far, we are in a good equilibrium and we have nothing to fear.

Answer 9

Various parameters are used to denote the water content of the atmosphere.They are absolute humidity, specific humidity,humidity mixing ratio,relative humidity and dew point temperature.

Among these,absolute humidty is directly  proportional to temperature.It increases as the temperature increases and decreases as the temperature decreases and is a good indicator of the actual moisture content in the air(Absolute humidity of a sample of air is the mass of the water vapour contained in a given volume of moist air).As you go up in the atmosphere,the temperature usually decreases and hence the absolute humidity also decreases,that too, very rapidly.This means that moisture content decreases as you go up.Major concentration of moisture content is confined to the troposphere and that is why 99 percent of the weather phenomenon occur in the troposphere only.This is the  reason why high clouds like cirrus, cirrostratus, cirrocumulus etc(which form above 6000 metres) do not produce any precipitation owing to lack of adequate moisture in these clouds.

So,practically there is no chance of any water vapour escaping into space.

Sometimes,a silvery luminous cloud is seen on summer nights in high alttitudes(about 80-85 km) which is called Noctilucent cloud.It has not been confimed whether this contains ice crystals or dust as no moisture is available at that height.

Answer 10

That sounds impossible to me. First of all there stops being air or a significant amount of it anyway at about 52,000-57,000 ft. So logically I don't know what the water would be transported by. There is no wind that far. I'm sure that we would have been like Mars by now, I mean the earth is how old? But water remains.
