Many
different
geographic
and
human
factors
have
affected
economic
development
throughout
history
.
One
factor
that
has
long
been
important
to
economic
development
is
water
.
For
most
of
human
history
,
people
and
civilizations
have
been
near
____________________
to
survive
.
It
is
used
for
drinking
,
cooking
,
cleaning
,
and
growing
.
Rivers
and
oceans
are
also
used
to
transport
goods
from
one
place
to
another
on
____________________
.
People
even
dug
a
new
waterway
shortcut
called
the
____________________
to
be
able
to
ship
products
from
the
Atlantic
Ocean
to
the
Pacific
Ocean
without
going
all
the
way
around
South
America
.
Unlike
water
,
____________________
are
a
physical
feature
that
can
make
it
more
difficult
to
ship
products
across
the
country
or
world
.
Especially
before
airplanes
and
and
highways
,
goods
were
moved
by
____________________
and
wagons
.
It
was
very
difficult
to
get
across
the
mountains
to
trade
things
with
people
on
the
other
side
.
Humans
have
invented
new
ways
to
get
products
,
people
,
and
money
around
the
world
.
Airplanes
can
move
smaller
amounts
of
goods
quickly
across
mountains
or
oceans
.
Dynamite
has
allowed
tunnels
to
be
built
through
mountains
for
cars
and
trains
.
It
is
not
as
important
to
live
next
to
water
as
it
used
to
be
because
of
automobiles
.
A
long
time
ago
,
even
boats
were
new
transportation
technology
!
In
the
1700's
-
1900's
,
new
,
large
boats
were
used
to
transport
goods
and
people
between
Europe
,
Africa
,
and
the
new
lands
called
North
and
South

Named
after
Christopher
Columbus
,
this
trade
triangle
was
called

From
boats
on
water
to
____________________
in
the
sky
,
people
keep
inventing
new
ways
to
move
goods
and
make
money
.
