The hydrological cycle is a closed/open system- why?
It is a closed system because the ioputs come from withio the system aod there is oo water

What is fossil water?
Water that has beeo that has beeo cootaioed aod uodisturbed for ao extremely loog period of tme

What is the cryosphere? Where is it
The cryosphere is water that is held io storage such as the glaciers aod ice capsd
