they are made of gases and vapors.

If you went soaring in a glider (after release by the tow plane) you could actually drift higher and higher under a separate cloud (but not above the unobstructed sunlit land). There is a constant updraft and you can almost sense that the cloud is still growing and expanding as moist air rises, cools and condenses and has no limiting form. Of course clouds can also blanket the sky blocking out all direct sunshine and can exist even in moonlight. Up close, a cloud looks exactly like a fog bank and in fact can shroud many a mountain top.

a guess from me would be that the Earth's winds are too variable for the clouds to take on one sort of shape and keep it.... the clouds that we see on Jupiter, for example, must be stuck in a very tight pattern for them to stay so evenly patterend... and the Great Red Spot, that's been a cloud pattern for how long?.... there must not be anything like mountains or valleys to change up the directions of the wind, then, huh?... like here on Earth, even a good strong air current like the Jet Stream sure moves around a lot and the clouds that travel with it have to change accordingly, yes?....with so many different types of clouds, diff temperatures, different ammounts of water vapor, etc, it would be very hard for one set pattern to survive here very long.... even our 'best' pattern, a hurricane, can't hang on for long.....

Cloud formation depends upon(1) convection due to local heating of the surface(2)lapse rate(if it is steep,convection will reach more heights leading to formation of thunder cloud)(3)Moisture content in different layers within the troposphere and (4) wind speed at different levels.
Clouds are classified into two main groups;rounded clouds known as cumulus and layer clouds known as stratus.
If there is convection ,cumulus clouds are formed,otherwise stratus type of clouds are formed.

Aside the fact that clouds are nothing but fog and travel with the wind, they are constantly forming and dissolving depending on pressure, temperature and humidity. On some days it can be well observed that the wind pulls out fragments from a cloud which then dissolve.

It will depend on the humidity of the environment. I think the cumulus clouds don't have permanent shape.

because clouds are not a solid compund they take the shape of the container they are in, b/c the container is the atmosphere they take whatever shape the wind currents blow them into

because they are just clumps of water vapour which has no form and also the wind gives the clouds different shapes.

i guess it consists of water and water has no permanent formation.

easy,because of wind.
