Sand is a special unique ability and also elemental
ninjutsu that cannot be
made or formed by chakra.
However, the user can unite
his chakra with pre-
existing sand on the ground
and gather more sand by
breaking down the earth.
Due to this matter, Sand is
strong against fire and also
sand is strong against earth
as well. But Sand is weak
against water since the
sand turns to mud once
water make contact with it.
It makes the sand weak and
slow. It is also weak
against lightning displayed
when Sasuke's chidori-
infested sword was able to
pierce through Gaara's
shield of sand.
Weakness : Sand is quite
weak against lightning
however, as lightning has
pure destructive and
piercing force, which can
easily break through it.
Sand is weak against Water
too, as it turns into hard
mud when it clashes with
Water.
Is strong against: Sand is
Strong against Wind, as
Sand is purely fine
particles, which when come
in contact with Wind, a sand
storm forms. Similarly,
when Sand is of a weaker
Rank, and Wind of a high
rank, Wind carries away the
Sand particles, and instead
re-directs it at the user
himself.
Also high ranked Sand is
strong against Fire, but
when it's of a very weaker
rank, it turns into glass, due
to the intensity and heat of
the flames.
