Although Earth may be accurately described as a watery planet because
so much of its surface is covered by oceans, water as a resource is far from
abundant. This is because about 97 percent of the world's water is salt water,
(注1)
which is unsuitable for drinking, for irrigation, and even for many industrial
s purposes. Fresh water (account for only about 3 percent of the total supply.
Of this, less than 0.5 percent is readily available from rivers and lakes, which
nevertheless provide 80 percent of the water used in industry and agriculture
worldwide. The water supply may appear to be increased by natural means
such as rain, or by artificial means such as drilling wells, but the amount
10 available on the planet is constant. It is continuously recycled in the water

the total water in the cycle. Water evaporates from the surface of the oceans,
leaving behind the salt. Some water also evaporates from rivers, lakes, the

the atmosphere and cools. As it does so, it condenses to form water droplets
high in the atmosphere. These droplets come together to form clouds. Their
(注3)
weight causes them to fall from the clouds as rain, snow or sleet-some of
which falls on land, where it enters the next phase of the water cycle, and
20 some over the oceans, returning the water to its source. On cold nights, the
water vapor in the air near ground level condenses on cold surfaces such as
glass of buildings and cars and forms on plants as (de). The fresh water
in the rain runs off the land streams and rivers into the oceans, or evaporates
into the atmosphere again.
(注4)
A large part of the water that falls on the land as rain and snow
penetrates deep into the ground, where it is stored in the spaces between
rocks, called aquifers. This water is called groundwater. Aquifers (eg,
underground springs and streams, which carry groundwater to the surface and
to rivers, lakes and streams, where it evaporates or returns to the ocean.

(注6)
Aquifers are replenished by precipitation falling on the land and sinking into
the ground, but the process of water circulation underground is very slow

compare with the process on the Earth's surface. Shallow groundwater
may be recycled within a year, but in deep aquifers it may take thousands of
years
