Cumulus clouds are detached clouds seen on sunny days, stratus clouds are gray, thick and cause drizzle and cirrus clouds are wispy, thin clouds composed of ice crystals. Each type of cloud has unique characteristics reg... More » Science Earth Science Atmosphere

Hail is typically associated with cumulonimbus clouds. The formation of hail is caused by the supercooling of uplifted liquid below freezing temperatures during severe thunderstorms. More » Science Weather & Tides Clouds

Cumulus clouds are comprised of water droplets, water vapor, super-cooled water droplets and ice crystals (when the freezing point is in the middle of the cloud), according to Northern Michigan University. Cumulus clouds... More » Science Earth Science Atmosphere

Different types of clouds vary in distance from Earth's surface, but range from quite near the ground to as high as 50,000 feet. Heights of the three main types of clouds also vary depending on latitude. More » Science Earth Science Atmosphere

Thunderstorms originate in cumulonimbus clouds. Warm, humid air rises then cools, creating moisture to form the cloud. Thunderstorms produce heavy rain, strong winds and sometimes hail. More » Science Earth Science Atmosphere

Snow occurs when water droplets in clouds freeze, and these droplets then act as a nucleus onto which molecules of water vapor adhere, forming larger ice crystals. Once the growing snowflake is too heavy for the movement... More » Science Weather & Tides Snow
