A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.
Asked in Meteorology and Weather, Clouds
Why are clouds white?
The whiteness of the clouds is due to light of all colors being dispersed by the water/ice of the clouds. Clouds quite a distance away appear yellow due to the blue wavelengths being dispered more than the yellow and red wavelengths by the air and particles in the air (the 'clear' sky is blue!) Not all clouds are pure white, however, for those that are white, it is due to their altitude and the reflection of sunlight. For example, a cirrus cloud has...

What is the boundary between two air masses of different temperature humidity or density called?
The line where these two air masses meet is called a front. If cold air advances and pushes away the warm air, it forms a cold front. Cold fronts are associated with rain following the front itself. When warm air advances, it rides up over the denser, cold air mass to form a warm front. Warm fronts are associated with rain leading the front itself. If neither air mass advances, it forms a stationary front. If dry air advances into moist air and there is...
What is the difference between a cold front and a warm front?
Cold fronts are defined by cold air advancing, sliding under and displacing warmer air - they are steeper and move more quickly. Warm air cannot displace cold air easily because it is less dense. Therefore, it rides up and over it, producing stratus and nimbostratus clouds where light precipitation falls. the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system. ...
Why does your home central air conditioner run but not blow cold air?
do you have your a/c set to fan? not a/c? otherwise you might need to contact your local a/c repair man and e will tell you you need a charge of freon in your system. ---- Why not to start checking the simple points like the filter, duct mechanism, etc. Not so simple to give a "One Size Fits All" answer for but here are a few things to check. 1) when the system is running does the outside unit kick on? That is...
What is Mars made of?
Mars is made of rock and iron oxides. It's surface is covered in mountains, volcanoes, valleys, ice caps and dried up river beds. Mars is also very dry like a desert. It is also red because of the iron oxide in the pulverized rock dust. Mars is a planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, deserts and polar ice caps of Earth. ...

What is the boiling point of hydrogen gas at STP?
1) Hydrogen GAS does not boil, simply because a gas is beyond the boiling stage. 2) STP (Standard Temperature and Pressure) is a set variable. Therefore, this question is syntactically incorrect, because you are asking: What is the boiling point of 'substance' at X°C and X psi, in which case you can't answer because of the already given temperature. --------------------------------------------------------------------------------------------------- Just for two other ways that are similar to your question that can be answered are... Q: What is the boiling point of hydrogen at...

Can an isolated thunderstorm become a tornado?
A thunderstorm does not become a tornado. It can produce one. Yes, though. If the atmosphere is unstable enough and there is enough low-level wind shear, then an isolated storm can produce a tornado. ...
What is a four winds shotgun?
It's possible to make a shotgun from common steel plumbing parts. It takes four parts and can not be identified as a firearm when disassembled. So you can throw the parts to the four winds and nobody can charge you with possessing a firearm. ...

Does the ash cloud have carbon dioxide it it?
definition of ash : ash is a residual product after any combustion process after a perfect combustion of any fuel we get ash hence it is a product which not have any combustible product in it . that's why i think ash does not contain carbon compound because carbon is highly combustible . in this world everything contain carbon inside it but i think ash is a alone example of non carbon product...may b it contain very few amount of carbon...
What does condensed mean in science?
Condensation is the opposite of evaporation. It takes place when water vapor in the air condenses from a gas, back into a liquid form, and leaves the atmosphere, returning to the surface of the Earth. Usually in order for condensation to take place, the atmosphere must be fully saturated. In other words, the maximum vapor pressure must have been reached. In addition to being saturated, the nature of water requires that their be a surface upon which water can condense. This surface might be...

Asked in Tornadoes, Clouds
What kinds of clouds form tornadoes?
Technically, it's a process of multiple cloud levels. Tornadoes form from Funnel Clouds, which form from Wall Clouds, which form along the base of Cumulonimbus clouds. So you start with a Cumulonimbus cloud (also known as a thunderhead or thunderstorm cloud) and a wall cloud can form along the base it. A wall cloud is a lowered base of a storm that is rotating. Attached to several wall clouds, especially in moist environments, is a tail cloud,which is just a band of...
What is the difference between partly cloudy and mostly sunny?
Believe it or not, there is a difference. It relates to the average amount of cloud cover expected. Would you believe partly sunny means more cloud cover than partly cloudy? Can be confusing to the public...mostly sunny means more sun than partly cloudy does, while partly sunny means more clouds than partly cloudy does. Anyway, from least cloud cover to most, the scale is: sunny, mostly sunny, partly cloudy, partly sunny, mostly cloudy, cloudy. Mostly sunny means more sun than clouds, partly...
