Does rapidly flowing water cause water to evaporate?





Which of these leaf types most effectively reduces the amount of water lost to evaporation?- broadleaf deciduous, cactus spines, needles of a coniferous tree or palm fronds?





Are old growth forrests fairly common in North america or are they gone forever, or are they the climax forrest for their region, or home to rich diversity?

Cactus, of course, are designed for the minimum amount of water loss through evaporation. Palm fronds and coniferous would also be good choices if you are interested in water loss although they both need a lot of water to stay healthy. Broadleaf deciduous would have the most water loss.
Reply:yes
Reply:Water flowing rapidly does not in and of itself cause evaporation but faster flowing water exposes more water (i.e. surface area over time is greater) than slower water and thus evaporation should be higher.





Needles.





Diversity.
Reply:I believe the answer by "the voice of reason" was accurate and succinct





I would add that whether old growth forrests are considered "common" depends on your definition of common





there are hundreds of thousands of acres of old growth forest in North America
