What are clouds? What can we learn about the weather by watching clouds?
Cloud Types:
High Clouds (16,500-45,000 feet)
Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands.
Low Clouds (less than 6,500 feet
Cumulonimbus clouds grow on hot days when warm, wet air rises very high into the sky. From far away, they look like huge mountains or towers.
