This
Flash
animated
slide
show
illustrates
the
development
of
a
waterfall
by
demonstrating
the
way
that
soft
rocks
are
more
quickly
eroded
downstream
than
hard
rocks.
The
animation
also
reveals
the
way
rapids,
steep
backwalls,
plunge
pools,
overhangs,
and
gorges
develop
as
well
as
the
way
waterfalls
retreat
up
