Document Summary

Colder atmospheres; air can hold less moisture no snow or precipitation at 12 months that it stays <0 c: active layer = permafrost top soil that thaws each year, global warming; deeper thaw depth. This course goes beyond the science of water, also looks at other realms. Look at pdf on water statistics on canada; it(cid:495)s online: most of earth(cid:495)s water is salty; 2. 5% is freshwater, (cid:882). (cid:888)(cid:887)% of earth(cid:495)s water is liquid freshwater 0. 01% is in rivers/lakes ; only that. Freshwater resources; flow rates (volume/time) and volume is accessible: volume = length3, cumec = cubic metres. Si units = l, km3, m3, cm3, ml. 1km3 = 1 x 109 l or 1 billion litres. Renewable unlimited: water is thus a resource, non-renewable water extraction = effectively mining water. Canada is not as water-rich as it appears location of the water relative to the.
