Cirrus-usually high in the sky and extremely cold (so cold that the water droplets are frozen solid), they look like tufts of hair
Cumulus-may become extremely high and can develop into cumulonimbus clouds which create thunderstorms
Cirrus Fibratus/Fioccus-thicker than regular cirrus clouds, and covers much more area
Altocumulus undulates-forms bands across the sky (which have gaps in-between)
Stratus-usaully bring rain or snow, they create a low blanket (very thick) across the sky
Strata cumulus-cover the sky with masses of
large rounded clouds
When moisture from water forms, it becomes cool and turns into vapor, then it evaporates. The moist air (which becomes frozen) evaporates into the sky and reforms into a cloud. Then the cloud releases the frozen water droplets (which melts on its way down by the warm air) and then becomes rain.
