Rockfall
deposit
close
to
the
source
area
(Photo
B).
(a)
List
all
of
the
grain
sizes
that
you
see
or
that are
likely
to
be
present
in
the
rockfall
deposit
shown
in
photo
B
(also
refer
to
Fig.
6.2).
The
largest
sediment
grain
in
B
is
approximately
2
m
long.
Use
the
grain-size
class
names
listed
in
Fig.
6.15.
The
likely
grain
sizes
present
in
the
rockfall
shown
in
photo
B
are
gravel,
boulders,
pebbles,
sand,
and
silt.
(b)
How
would
you
describe
the
sorting
of
sedimentary
grains
in
the
rockfall
deposit?
Use
the
terms
in
Fig.
6.16A.
The
sorting
of
sedimentary
grains
in
the
rockfall
deposit
can
be
described
as
poorly
sorted.
(c)
How
would
you
describe
the
shape
of
sedimentary
grains
you
can
see
in
the
rockfall
deposit?
Use
the
terms
in
Fig.
6.168.
The
shape
of
sedimentary
grains
in
the
rockfall
deposit
can
be
described
as
very
angular.
(d)
If
the
sediments
in
the
rockfall
deposit
were
lithified
together
as
they
currently
rest,
without
any
further
movement
downslope,
what
kind
of
sedimentary
rock
would
they
form?
If
the
sediments
in
the
rockfall
deposit
were
lithified
together
as
they
currently
rest
they
would
form
a
conglomerate.
