-+ The main process In the cycle is Ihe global transfer of water from Ihe
atmosphere 10 the land and oceans and back to the atmosphere Together, the
oceans, ice caps and glaciers account lor more than 99% of the total water, and
both are generally unsuitable for human use because of salinity (seawater) and
location (ice caps and glaciers) Only about 0.001% of the total water on Earth
is in the atmosphere at anyone time However, this relatively small amount of
water in the global water cycle, with an average atmospheric residence time of
only about 9 days, produces all our freshwater resources through the process
of precipitation
-+ On a global scale, then, total water abundance Is not the problem; the
prob-lem is water's availability In the right place at the right time in the right form
