Clouds are composed of small water droplets and/or ice crystals, depending on temperature. It's H2O in some form. Lower clouds are generally water droplets, while high clouds such as cirrus clouds are made up of ice crystals.

Our atmosphere -- the gaseous envelope surrounding the Earth -- is composed of several gases, primarily nitrogen, oxygen, argon and carbon dioxide. Water vapor and minute bits of dust, salt and clay-silicate particles swirl about in the mixture.\nThe atmosphere has four vertical layers that radiate from Earth and vary by temperature and composition. Proceeding from the ground outward, they are the troposphere, stratosphere, mesosphere and thermosphere.\n\n\nAll of the “optical phenomena” – halos, sun dogs, sun pillars, coronas and rainbows – are produced at specific levels in the troposphere, which extends from the surface up to about 12 kilometers, eight miles or 42,000 feet depending on which measuring stick you pick. Here, the temperature decreases rapidly with altitude – averaging 59°F at the surface and a right chilly -69°F at 11 km. Commercial jets fly in the upper reaches of the troposphere.\n\n\nHigh-level cirrus clouds form in extremely cold air where water vapor condenses on tiny dust and salt particles to form ice \ncrystals.\nHence these are responsible for various phenomena circles aroound light emitting/reflecting bodies on the sky, and the rings are formed depending upon how the light gets scattered and the colours also depend on that.\nVR

rain comes from clouds. clouds are actually water vapour floating in air. when they become really condensed due to a drop in temperature then they form large drop of water which cant stay afloat and so rain happens.

When it is very cold clouds do freeze. In fact even on a hot summer’s day the high clouds are normally frozen. \n\nThe reason they don’t; fall down is because ice isn’t any heavier than liquid water. When you freeze the droplets that make up a cloud they don’t gain any weight, they just turn from a liquid to a solid. You can prove this your self by  filling an ice cube tray with water and weighing it. After you freeze it solid you can weigh it again and the weight will be EXACTLY THE SAME.\n\nBecause frozen clouds made of ice are no heavier than clouds made of liquid water there is no reason why they should fall down. \n\nClouds are made of billions of tiny droplets of water. You can see this for yourself if you go outside on a foggy night with a flashlight. Fog is nothing but a cloud that has formed very close to the ground, and the flashlight beam will show that the fog cloud is made up of lots of little drops of water floating in the breeze. \n\nA cloud is kept in the sky because the wind is constantly blowing those tinny water drops upwards and preventing them from falling. When those droplets freeze they are still blown around in the wind like tiny little snowflakes (but they are not snowflakes).

I can't remember exactly but its something like this.  Large, tall clouds form.  Vapour freezes (hail). Updraught occurs which is strong enough to support the weight of the hailstones inside the cloud.  Hailstones move and collide  getting bigger until updraught can't support the weight anymore and they fall, air temperature is cool enough to keep stones frozen until they reach the ground.

Clouds are made of water vapor.  You inhale clouds every time you walk into a patch of fog, because fog is just a cloud at ground level.  Clouds are formed when water evaporates from the surface of the Earth and makes its way upward.  The water condenses and we get a cloud.  When clouds get too laden with water, it falls in liquid form and we get rain.

Contrails are condensation trails (sometimes vapour trails): artificial cirrus clouds made by the exhaust of aircraft engines or wingtip vortices which precipitate a stream of tiny ice crystals in moist, frigid upper air. Contrary to appearances, they are not air pollution as such, though might be considered visual pollution.

Fog is made when water vapor condenses, the same as clouds.\n\nTechnically they are the same thing. Fog is obviously at lower altitudes.\n\nClouds form when warm moist air rises, cools (reaches dew point), & condenses on small particulates (aerosols) in the atmosphere.\n\nFog can form in many different ways. There are about 5 or 6 that I know of...\n\nRadiation: forms on cool clear nights\nSteam fog:forms over water when the water is still warm but the air is cool (think fall nights)\nAdvection: moist air flowing over cool water or land (think San Francisco)\nvalley fog\nprecipitation fog\n\nknow less about the last 3.\n\n:)

3 things r neede for cloud formation...cooling of air, presence of water vapour (relative humidity shud be close to 100%), and condensation nuclei( like dust particles).\ndunno who found it, sorry

Cirrus clouds. The puffy ones are cumulus, and dark ones nimbocumulus. The cirrus clouds are really high up.

did you mean how do clouds form?\n\nIf so, they form from water evaporating on the surface of the earth. As the vapour rises, it reaches cooler, higher areas of the atmosphere and the vapour begins to condense, around microscopic particles in the air. Once this process has started, other molecules will start to join in, until the vapour condenses and clumps together. When enough forms, it is no longer lighter than air, and rain will occur.

All types of clouds can be found throught the year in St. Paul, Minnesota. I can't name them all, but go to the weather channel. They have all kinds of information.

"Cloud Condensation Nuclei"\n\nThese are the suspended particles that water condenses around in order to form a rain drop. It may be dust, smoke, salt, or any other solid that is in aerosol form in the atmosphere.

wikipedia.com\n\n\nA cloud is a visible mass of condensed droplets or ice crystals suspended in the atmosphere above the surface of the Earth or another planetary body. The branch of meteorology that studies clouds is nephology.\n\nOn Earth, the condensing substance is water vapor, which forms small droplets of water (typically 0.01 mm of ice crystals) that, when surrounded with billions of other droplets or crystals, are visible as clouds. Clouds reflect all visible wavelengths of light equally and are usually white, but they can appear grey or even black if they are so thick or dense that sunlight cannot pass through.\nContents\n[hide]\n\n    * 1 Cloud formation and properties\n          o 1.1 "Hot Ice" and "Ice Memory" in cloud formation\n    * 2 Cloud classification\n          o 2.1 High clouds (Family A)\n          o 2.2 Middle clouds (Family B)\n          o 2.3 Low clouds (Family C)\n          o 2.4 Vertical clouds (Family D)\n          o 2.5 Other clouds\n          o 2.6 Cloud fields\n    * 3 Colors of clouds\n    * 4 Global dimming\n    * 5 Global brightening\n    * 6 Clouds on other planets\n    * 7 See also\n    * 8 External links\n\n[edit]\n\nCloud formation and properties\nA variety of cloud formations.\nEnlarge\nA variety of cloud formations.\nGlobal scheme of cloud optical thickness.\nEnlarge\nGlobal scheme of cloud optical thickness.\n\nClouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. This can happen in three ways.\n\n1. The air is cooled below its saturation point. This happens when the air comes in contact with a cold surface or a surface that is cooling by radiation, or the air is cooled by adiabatic expansion (rising). This can happen\n\n    * along warm and cold fronts (frontal lift),\n    * where air flows up the side of a mountain and cools as it rises higher into the atmosphere (orographic lift),\n    * by the convection caused by the warming of a surface by insolation (diurnal heating),\n    * when warm air blows over a colder surface such as a cool body of water.\n\n2. Clouds can be formed when two air masses below saturation point mix. Examples are breath on a cold day, aircraft contrails, and Arctic sea smoke.\n\n3. The air stays the same temperature but absorbs more water vapor into it until it reaches saturation.\n\nThe water in a typical cloud can have a mass of up to several million tonnes. However the volume of a cloud is correspondingly high, and the net density of the relatively warm air holding the droplets is low enough that air currents below and within the cloud are capable of keep it suspended. As well, conditions inside a cloud are not static: water droplets are constantly forming and re-evaporating. A typical cloud droplet has a radius on the order of 1 x 10-5 m and a terminal velocity of about 1-2 cm/s. This give these droplets plenty of time to re-evaporate as they fall into in the warmer air beneath the cloud.\nCumulonimbus cloud\nEnlarge\nCumulonimbus cloud\n\nMost water droplets are formed when water vapor condenses around a condensation nucleus, a tiny particle of smoke, dust, ash, or salt. In supersaturated conditions, water droplets may act as condensation nuclei.\n\nWater droplets large enough to fall to the ground are produced in two ways. The most important is through the Bergeron Process, theorized by Tor Bergeron, in which supercooled water droplets and ice crystals in a cloud interact to produce the rapid growth of ice crystals, which precipitate from the cloud and melt as they fall. This process typically takes place in clouds with tops cooler than -15°C. The second most important process is the collision and wake capture process, occurring in clouds with warmer tops, in which the collision of rising and falling water droplets produces larger and larger droplets, which are eventually heavy enough to overcome air currents in the cloud and the updraft beneath it and fall as rain.

The shape is completely random, based on how air currents (wind and updrafts) are moving around and inside the cloud. You get so many cloud shapes over time that a few random patterns are bound to resemble something else we're familiar with, such as a heart or a dog.
