Is there water in the whole atmosphere, or just to a certain altitude????

Question

If there is water in the whole atmosphere is this not what reflects the sun to turn the sky BLUE????

Answer 1

Nearly half the total water in the air is between sea level and about 1.5 km above sea level. Less than 5-6% of the water is above 5 km, and less than 1% is in the stratosphere, nominally above 12 km. Look at Figure 1 from this link...

The blue color of the sky is due to Rayleigh scattering of the shorter visible wavelengths (of electromagnetic radiation) by gases in the atmosphere.

Answer 2

Most of the earth`s water vapour is in the troposphere and the tropopause, all the weather happens in these layers. The troposphere starts at sea level and extends between 8 to 14.5 Km high (5 to 9 miles) the tropopause separates the troposphere from the stratosphere. Both of these layers together are called the lower atmosphere. A small amount of water vapour is present in the stratosphere.

Answer 3

There's water in our atmosphere. It gets there when water from streams, lakes and oceans evaporate, when plants and trees transpire, when we respire... The result of this is the humidity in the air. When it is 20%, the atmosphere has 20% of water.

The different densities of the atmosphere due to its altitude causes light to refract and hence the blue sky.

Answer 4

a certain amount of water exist in all our atmosphere, but it is far more concentrated at lower levels.

Answer 5

There's water in any air that has humidity.

Answer 6

There is too much to read in this web so u can find in this web
