Most
of
the
____________________
is
found
in
the
oceans
.
Water
moves
from
one
ocean
to
the
other
in
rivers
called
____________________
.
Ocean
currents
are
parts
of
the
surface
layer
of
the
ocean
that
move
continuously
in
a
particular
____________________
forming
rivers
in
the
ocean
.
Wind
blowing
over
the
surface
of
the
ocean
transfers
energy
to
the
water
and
causes
____________________
to
form
.
Waves
are
the
alternating
rising
and
falling
of
____________________
.
Tides
are
the
alternate
rise
and
fall
of
the
____________________
and
seas
and
the
bodies
of
water
that
are
connected
to
them
.
These
changes
in
the
surface
level
of
the
ocean
are
caused
by
the
____________________
force
of
the
moon
acting
on
the
oceans
and
seas
.
The
force
of
gravity
is
____________________
on
the
parts
of
the
earth
closest
to
the
moon
and
____________________
on
the
parts
of
the
earth
farthest
form
the
moon
.
Water
on
the
side
of
earth
nearest
the
moon
is
pulled
away
from
Earth
by
gravitational
force
.
On
the
side
of
the
earth
farthest
from
the
moon
,
the
solid
earth
is
closer
to
the
moon
than
the
water
resulting
in
the
earth
being
pulled
more
toward
the
moon
than
the
water
.
This
causes
a
tidal
____________________
.
The
highest
tides
occur
when
the
moon
and
the
sun
are
in
line
with
Earth
.
The
motion
of
the
ocean
causes

and
erosion
to
the
shoreline
.
