What type of cloud is associated with patchy or sheet-like formations?

The type of cloud that is associated with patchy or sheet-like formations is the stratocumulus cloud. Stratocumulus clouds tend to develop in low altitudes and often appear as a layer of white or gray clouds that cover the sky in a sheet or are present in patches. They can create a somewhat broken appearance but do not typically bring precipitation, which distinguishes them from other cloud types.

Cumulonimbus clouds, on the other hand, are towering vertical clouds associated with thunderstorms and severe weather, not characterized by patchiness. Stratus clouds are also sheet-like but tend to be uniform and cover the sky completely, often leading to overcast conditions. Nimbostratus clouds are thick and produce continuous, steady precipitation, and although they can cover the sky, they do not exhibit the patchy characteristics of stratocumulus clouds.
