The
____________________
material
is
also
known
as
regolith
.
It
is
the
material
that
is
____________________
to
become
soil
.
It
affects
the
:
____________________
of
the
soil
,
as
____________________
material
weathers
faster
creating
deeper
soils
;
the
____________________
of
the
soil
,
that
is
,
how
coarse
or
fine
the
soil
is
.
This
is
determined
by
the
____________________
of
sand
,
silt
and
clay
in
the
soil
.
It
also
affects
the
soil's
____________________
,
that
is
,
the
water
drainage
in
the
soil
and
the
____________________
of
the
soil
.
Dark
rocks
lead
to
____________________
coloured
soils
.
The
____________________
is
responsible
for
the
distribution
of
world
soil
types
.
Climate
affects
the
rate
of
____________________
of
the
parent
rock
.
This
is
____________________
in
hot
and
wet
climates
.
____________________
affects
the
mineral
content
in
the
soil
through
leaching
and
capillary
action
.
On
the
other
hand
,
____________________
also
affects
the
humus
content
,
which
is
fastest
in
hot
and
wet
countries
.
The
____________________
or
relief
is
the
shape
of
the
land
.
As
the
____________________
of
the
land
increases
,
precipitation
,
cloud
cover
and
wind
____________________
,
while
temperatures
and
length
of
the
growing
season
____________________
.
The
____________________
is
the
direction
a
slope
faces
.
____________________
facing
slopes
are
warmer
and
drier
.
The
____________________
of
the
slope
also
affects
the
____________________
of
water
in
the
soil
and
soil
____________________
.
____________________
slopes
usually
,
lead
to
drier
,
and
thinner
soils
.
The
____________________
,
like
plants
,
bacteria
and
fungi
,
and
animals
all
interact
in
the
____________________
cycle
.
Plants
take
up
nutrients
from
the
soil
and
return
them
to
it
after
they
die
.
Also
micro
-
organisms
,
including
worms
and
termites
,
____________________
and
____________________
the
soil
.
____________________
are
increasingly
affecting
soil
development
,
through
the
addition
of
fertilisers
,
the
breaking
up
of
horizons
by
ploughing
,
draining
or
irrigating
land
,
by
accelerating
or
controlling
soil
erosion
.
Soils
take
____________________
to
form
,
usually
between
3
,
000
to
12
,
000
years
are
needed
to
produce
a
sufficient
depth
of
mature
soil
for
farming
.
Newly
formed
rock
contains
many
____________________
of
the
parent
material
,
but
with
time
,
they
acquire
____________________
characteristics
resulting
from
the
addition
of
organic
matter
,
the
activity
of
organisms
and
from
leaching
.
