Physical factors affecting water supply
The distribution of water globally is related to the Earth's
climatic zones
Regions near to the equator receive high levels of

While some tropical areas suffer recurring drought
Rainfall may also vary with the seasons
Equatorial areas such as the Amazon lowlands have two
distinct periods of wet weather per year
Whereas the monsoon lands of Southeast Asia have
one very distinct wet season
High mountains with snowpack hold vast reserves of
water, some of which is released during the summer…read more
