Water
____________________
71%
of
the
Earth's
____________________
.
We
can
____________________
between
two
groups
:
____________________
water
(
or
sea
water
)
and
____________________
water
.
Salt
water
is
found
in
____________________
and
____________________
.
It
represents
more
than
97%
of
the
total
water
on
____________________
.
____________________
water
is
found
in
____________________
,
lakes
,
____________________
,
groundwater
and
at
the
poles
.
It
____________________
less
than
3%
of
all
the
water
on
our
____________________
.
Water
is
always
____________________
and
changing
its
____________________
state
.
This
process
is
called
the
____________________
____________________
.
There
are
several
____________________
in
the
water
cycle
:
-
____________________
:
the
sun
____________________
up
water
on
the
Earth's
surface
and
turns
it
into
____________________
.
Water
vapour
leaves
the
Earth's
surface
and
goes
into
the
____________________
.
-
____________________
:
water
vapour
in
the
air
____________________
down
and
changes
back
into
liquid
,
forming
clouds
.
-
____________________
:
so
much
water
has
____________________
in
the
____________________
that
the
air
cannot
hold
it
anymore
.
The
clouds
get
____________________
and
water
falls
back
onto
the
Earth
in
the
form
of
rain
,
____________________
or
snow
-
____________________
:
when
water
falls
back
onto
the
Earth
,
some
of
it
____________________
into
the
ground
and
the
rest
____________________
into
the
oceans
,
rivers
or
lakes
.
