How is the water in icebergs involved in the water cycle?
icebergs are mostly found on mountain peaks.
the meltoff in summer causes rivers that form the drainage system.
this eventually snows back down
No, icebergs are pure water with very few contaminants. The salt is left behind when the water freezes. Are icebergs salty? No. Icebergs are comprised of pure fresh water. There may be some dust embedded in the ice and salt water may be on the surface but it does not penetrate the ice. Iceberg ice is quite safe to consume. from: http://www.wordplay.com/tourism/icebergs/
