Clouds form when air is cooled to its dewpoint or the temperature, if the air is cooled, it reaches saturation. Air can reach saturation in a number of ways. The most common way is through lifting. As a bubble or parcel of air rises it moves into an area of lower pressure (pressure decreases with height). As this occurs the parcel expands. This requires energy, or work, which takes heat away from the parcel. So as air rises it cools. This is called an adiabatic process.

The rate at which the parcel cools with increasing elevation is called the "lapse rate". The lapse rate of unsaturated air (air with relative humidity <100%) is 5.4°F per 1000 feet (9.8°C per kilometer). This is called the dry lapse rate. This means for each 1000 feet increase in elevation, the air temperature will decrease 5.4°F.

Since cold air can hold less water vapor than warm air, some of the vapor will condense onto tiny clay and salt particles called condensation nuclei. The reverse is also true. As a parcel of air sinks it encounters increasing pressure so it is squeezed inward. This adds heat to the parcel so it warms as it sinks. Warm air can hold more water vapor than cold air, so clouds tend to evaporate as air sinks.


Types of Clouds
There are four basic cloud categories observed in our atmosphere:
Cirro-form High-level clouds which form above 20,000 feet (6,000 m) and are usually composed of ice crystals. High-level clouds are typically thin and white in appearance, but can create an array of colors when the sun is low on the horizon. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation.

Nimbo-form Nimbus comes from the Latin word meaning "rain". These clouds typically form between 7,000 and 15,000 feet (2,100 to 4,600 m) and bring steady precipitation. As the clouds thicken and precipitation begins to fall, the bases of the clouds tend to lower toward the ground.

Cumulo-form Clouds look like white fluffy cotton balls or heaps and show the vertical motion or thermal uplift of air taking place in the atmosphere. The level at which condensation and cloud formation begins is indicated by a flat cloud base, and its height will depend upon the humidity of the rising air. The more humid the air, the lower the cloud base. The tops of these clouds can reach over 60,000 feet (18,000 m).

Strato-form "Stratus" is Latin for layer or blanket. The clouds consist of a feature-less low layer that can cover the entire sky like a blanket, bringing generally gray and dull weather. The cloud bases are usually only a few hundred feet above the ground. Over hills and mountains they can reach ground level when they may be called fog. Also, as fog "lifts" off the ground due to daytime heating, the fog forms a layer of low stratus clouds.

Suspended In The Air

In two simple sentences and not an essay of numbers and weather information from some other website like other answerer's gave:

The clouds are the top of rising air which extends further down below the cloud and therefore the cloud is in a way already at the ground and can't fall. Also, if the cloud were to somehow fall from lack of rising air below it, the descent would warm it and evaporate it in most situations.

Gawd, I hate answerer's that post whole pages from an encyclopedia along with tons that the asker didn't ask for.

Simple, clouds are continually forming usually from rising air. Cloud droplets are so tiny that they readily float in even calm air without descending. You've been in fog before, ever see the fog droplet when it is in front of your face? No, because it is tiny. Also clouds are made from evaporated water but that just means water that was changed from a liquid to a gas. They are created when air temperature drops below the dew point and the water which was formally in a gas form is now changed into a liquid form. Notice how cumulus clouds on a summer day all have flat bottoms at the same altitude? That is where the dew point in the atmosphere is. Below that, the water is a gas and above that the water is liquid.

The clouds are not condensed water.
They are formed from water vapour which is a gas like steam that is just beginning to condense.
Water vapour is lighter than air and when the air pressure is high the clouds rise and the humidity is low.
Only when the atmospheric conditions of temperature and pressure are right, will the clouds descend, condense to water and, fall as rain (or snow or hail).
As the atmospheric pressure decreases and humidity increases, is when we get 'Low Pressure Areas'.
The wind rises, the temperature falls, the clouds gather, the rains come and, may be accompanied by Thunder and Lightning.

The upper atmosphere has different pressure levels, so the clouds can only go so high before the air gets too thin.
