Cirrocumulus - Answers a cloud at a high altitude consisting of a series of regularly arranged small clouds
resembling ripples
Cirrus - Answers a wispy white cloud (usually of fine ice crystals) at a high altitude (4 to 8 miles)
Cumulonimbus - Answers a dark cloud of great vertical extent charged with electricity
Altocumulus - Answers A middle cloud, usually white or gray. Often occurs in layers or patches with
wavy, rounded masses or rolls, (puffballs)
