Multi layer clouds Nimbostratus clouds are very dark associated with large areas of precipitation. Above 18,000 feet

7 Stratus are generally the lowest (besides fog) and dont have much definition. Cumulus are puffy with distinct edges and have a bit of height Stratocumulus are generally clusters and have a popcorn like appearance. Mid-level clouds Altostratus covers the sky uniformly and it makes it hard to see individual features. Altocumulus are either patchy & scattered or linear bands.
