According

plate tectonics, the outer layer
01
the Earth Is

made
up
01
plates that are am-
tinually moving, and consequently, changing the relative position
01
the land and oceans. Building on
this theory, scientists have proposed that about
250
million years ago, there
was
only
one
landmass, a
huge continent thai
they have named Pangea, and
It
Inctuded
all
of the continents that
we
observe
today.
Bu
t about 200 million yean; ago. the plates caused Pangea to drift and break into a Northem
continent that Included North America, Greenland, Asia,
and
Europe, and I Southem continent that
contained South America,
India, Antarctica, and Australia.

By
about 135 million years
ago,
the ptates
had
separated the landmasses Into
more
or
less the seven continents that
we
recognize today and
positioned
them
lairly close to their current locations.
