I'm writing an article about the hydrosphere for my website GeoWorld. I'm dividing the hydrosphere into the following seven categories:
1) the sea 2) surface freshwater bodies 3) underground aquifers 4) cryosphere (glaciers, permafrost, etc.) 5) atmosphere (water vapor and precipitation) 6) water in living things (e.g. blood, sap, etc.) 7) man-made water bodies (e.g. dams and reservoirs)
I just wondered if anyone can suggest an appropriate term for these categories. I'm tentatively calling them hydrozones (not a real word; I just thought it sounded appropriate).
Lest I create any confusion, I should point out that the hydrosphere and cryosphere are two different, though overlapping, entities. Technically, hydrosphere refers to water in its liquid form, while cryosphere refers to frozen water. Water vapor (a gas) is also different.
So, in summary, I'm looking for a word that describes the seven major forms and states water is generally found in on Earth, as listed above. Feel free to coin new terms, as I did. ;)
