The
water
cycle
,
also
known
as
the
____________________
cycle
or
the
H2O
cycle
,
describes
the
continuous
movement
of
water
on
,
above
and
____________________
the
surface
of
the
Earth
.
The
mass
of
water
on
Earth
remains
fairly
constant
over
time
but
the
partitioning
of
the
water
into
the
major
reservoirs
of
ice
,
____________________
water
,
saline
water
and
atmospheric
water
might
be
different
.
The
water
moves
from
one
reservoir
to
another
,
such
as
from
river
to
ocean
,
or
from
the
ocean
to
the
____________________
,
by
physical
processes
.
The
water
cycle
describes
how
water
____________________
from
the
surface
of
the
earth
,
rises
into
the
atmosphere
,
cools
and
____________________
into
rain
or
snow
in
clouds
,
and
falls
again
to
the
surface
as
____________________
.
In
doing
so
,
the
water
goes
through
different
phases
:
liquid
,
____________________
(
ice
)
and
vapor
.
The
water
cycle
involves
the
exchange
of
energy
,
which
leads
to
temperature
changes
.
For
instance
,
when
water
evaporates
,
it
takes
up
energy
from
its
surroundings
and
cools
the
environment
.
When
it
condenses
,
it
releases
energy
and
warms
the
environment
.
These
heat
exchanges
influence
____________________
.
The
evaporative
phase
of
the
cycle
purifies
water
which
then
replenishes
the
land
with
freshwater
.
The
flow
of
liquid
water
and
ice
transports
minerals
across
the
globe
.
It
is
also
involved
in
reshaping
the
geological
features
of
the
Earth
,
through
processes
including
____________________
and
sedimentation
.
The
water
cycle
is
also
essential
for
the
maintenance
of
most
life
and
ecosystems
on
the
planet
.
