Antarctic Plate
The
Antarctic Plate
is a
tectonic plate
containing the
continent
of
Antarctica
and extending outward under the surrounding
oceans
. After breakup from
Gondwana
(the southern part of the
supercontinent
Pangea
), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional
mid-ocean ridge
systems. The adjoining plates are the
Nazca Plate
, the
South American Plate
, the
African Plate
, the
Indo-Australian Plate
, the
Pacific Plate
, and, across a
transform boundary
, the
Scotia Plate
.
