1. Cumulus clouds are the puffy white cotton ball clouds you see outside on most days.
- These clouds do not bring precipitation, but they can grow large enough to become darker, taller cumulonimbus clouds.
2. Cumulonimbus clouds are often called thunderheads.
3. Stratus cloud are layers of low clouds that cover the entire sky: these are the kinds of clouds that can bring all-day steady rains.
