Quizplus · Accepted Answer

Cirrostratus clouds are composed of ice crystals and are thin enough to allow light to pass through, creating a halo effect around the Sun or Moon. Altastratus and nimbostratus clouds are composed of water droplets, while stratus clouds are typically low and flat without the ability to create a halo effect. There is no such cloud type as "angelitus".
